The present study was aimed to record and analyze the prevalence of obstructive urolithiasis in domestic animals like cattle, buffalo, horse, goat, sheep, dog and cat presented at RVP-TVCC, Indian Veterinary Research Institute. A total of 777 cases were reported during the academic session starting from April 2018 to March 2019 from Bareilly and its surrounding regions. Incidence were highest among ruminants 92.92% comparing to other domestic animals 7.08%. Among the different animal species, caprine were found to be the most affected, followed by buffalo and canine. A positive correlation was noted between the occurrence of obstructive urolithiasis and the season with maximum number of cases being reported during the winter season December - February. The female to male ratios in urolithiasis affected animals were 1:81, 1:75 and 1:22 for buffalo, goat, and dog, respectively indicating higher occurrence in male animals. Majority of the goat 67.89% and buffalo 84.80% presented with obstructive urolithiasis were also found to be fed exclusively with a grain rich diet that are excess in phosphorous thereby contributing to urolith formation. The role played by behavioral changes associated with different seasons and the dietary status of the animal plays a significant role in the pathophysiology of urolithiasis. Such an interplay between the season and the dietary imbalance will lead to higher incidence of obstructive urolithiasis in domestic animals.

The aim of this study is to evaluate the contamination status of Iraqi rivers in the north of the Tigris river (Tikrit city) and the middle region of Euphrates (Babylon Governorate). In this study As, Zn, Fe, Pb, and Cu in the muscle tissue of carp fish were measured. The results show that the concentration of arsenic in the fish muscles in the middle region was 425.05 ppm higher than its concentration of about 192.25 ppm in fish muscle in the Tigris river with statistical significance (p < 0.05). Which it causes histopathological changes characterized by Zenker necrosis in skeletal muscle and infiltration of inflammatory cells with edema additional to edematous dermatitis. Other heavy metals in fish muscle were less than in fish muscles which agreement with the international legislation limits. Also, there were positive correlation ships between Zn and Pb and between Cu and Zn. While negative correlation has been detected between arsenic and both (Pb) and(Zn). This study is concluded that the accumulation of heavy metals causes histological changes in fish muscle provides an opportunity to assess fish health as well as information on possible health hazards coming from their environment.

The goal of this study was to modify three steps method for measuring protection rate of amino acids which has smaller size than nylon bag pores. To prepare the protected amino acids by the Schiff base method, each of the essential amino acids (methionine and lysine) in the aqueous solvent were brought to isoelectric pH and then reacted with the same molar ratio of aldehydes the reaction was refluxed for 30 minutes to 6 days (depending on the type of aldehyde used). The three-step in vitro method was used to estimate rumen insoluble protein in the rumen. In the manufacture of protected amino acid ligands, compounds with methionine amino acid had higher efficiency than lysine compounds and also glutaraldehyde ligands showed higher production efficiency compared to benzaldehydes. The glutaraldehyde lysine ligand showed the lowest release after 2 h of incubation in the rumen medium. At time 4 the methionine benzaldehyde ligand had the lowest release. Benzaldehyde had the lowest release at time 6 and 8. According to the results of this table, Lysine benzaldehyde had better resistance to different phases and methionine benzaldehyde had the lowest release rate compared to the other ligands. Based on this study, it can be concluded that the use of chemical methods to protect amino acids can be applied.

Caseous lymphadenitis is a chronic infection caused by Corynebacterium pseudotuberculosis that affects the lymphatic system, resulting in abscesses in the lymph nodes and internal organs. This study was conducted to determine the prevalence rate of caseous lymphadenitis among slaughtered sheep in Duhok abattoirs, Duhok, Iraq and to investigate to what extend rabbits can develop caseous lymphadenitis just like that in sheep. A total of 1052 carcasses of sheep were randomly selected (939 males and 113 females) and carefully inspected for detection any suspected caseous lymph adenitis. The isolated Corynebacterium pseudotuberculosis from lymph nodes of sheep carcasses were identified by PCR before used in in vivo infection in rabbits. Data revealed that the prevalence rate of caseous lymphadenitis was at 1.9% among the slaughtered sheep and the prevalence rates were higher in females and older ages than that of males and younger ages, respectively. Experimentally infected rabbits developed various clinical signs were ranging from in inappetence to sudden death, mainly during first week of infection. Histopathologically, the infected rabbits developed caseous lymphadenitis and pyogranuloma after a time point of 10 days post-infection. Liver, spleen and lymph nodes of infected rabbits showed caseo-necrotic foci with multiple micro-granulomas with presence of thick pyogenic membrane infiltrated with leukocytic cells; these findings are strictly resemblance to that reported in sheep. The obtained preliminary data of using rabbits as an animal model is promising which will enhance a better understanding the pathogenesis of caseous lymphadenitis in animals.

Exposure to LTE 2600 MHz microwaves is increasing very fast as new technologies and become accessible worldwide, and the smartphones being the main source of these waves. The aim of this study is to assess the thermal effect of 4G signals on rats. Forty adult Albino rats were used throughout the study, assigned as control and exposed groups, equally. Rats were kept in Plexiglas cages with intermittent exposure to LTE mobile-phone like signals at an average of 2h/day for up to 30 continuous days with SAR value of 0.982 W/kg. Infrared images were snapped immediately after the end of the exposure time, then one hour, two hours, and four hours later at a rate one collection/week during the study. IR images were analyzed by FLIR Tools software. The results exhibited variation in reflected skin temperatures in the exposed group compared to control images. Furthermore, the analysis of collected data revealed significant variations over the course of the study compared to the first week. The rise in skin temperature observed in response to exposure in the first week, which decreased gradually increased exposure and this drop in reflected skin temperature was significantly related to amount of exposure. The study concludes that the LTE 2600 MHz exposure under controlled laboratory conditions has a thermal effect on the rats.

The current study was done to investigate the effects of two doses 3and 6 mg/kg B.w. of the Platinum drug on the structure of the liver and kidney of pregnant mice, and embryos in addition to the weight of the mothers', embryos ,'maternal liver and kidneys, as well as some biochemical parameters, were established. For this study, thirty pregnant mice were used, divided into three groups (10 mice/group) as follows; group I (control group); animals were injected intraperitoneally (IP) with distilled water on the days 7th, 12th, and 17th of gestation. The other both groups II, and III were injected intraperitoneally (IP) with the selected doses above of the Platinum at the days 7th, 12th, and 17th of gestation, respectively. Microscopically, maternal and fetal' liver sections of group II revealed vacuolation, swelling, apoptosis, infiltration of inflammatory cells, congestion, degeneration, and presence of the extramedullary hematopoietic cells, respectively. Previous lesions were increased in group III. Maternal and, fetal kidney sections of group II revealed degeneration, expansion of Bowman's space, inflammatory cells infiltration into interstitial tissue, and blood capillaries congestion. However, the previous lesions showed more severity in group III. The drug caused a reduction in the body weight of the mothers, selected organs, and embryos. Biochemical assessment of the maternal serum AST, ALT, and ALP levels showed an increase in both experimental groups II and III, but to varying degrees. Moreover, both groups II and III showed an increase in the levels of the maternal BUN and, urea. Whist, group III showed a significant increase of the creatinine compared to the control group. In conclusion, using anticancer drugs during pregnancy will harm both mothers and fetal organs. The risk of these medications represents their ability to cross the placenta and enters the fetal body. Therefore, the drug may affect the formation of the fetal organs. The drug also alters the regulatory antioxidant mechanism in the maternal body during the treatment duration. The drug should be used under medical follow up.

The current study was conducted to investigate the role of alpha lipoic acid (ALA) against testicular toxicity- induced by lead acetate (PbAc) in rats. Four groups of adult Wistar albino rats (8 for each) were intubated daily for 56 days as follows; control (C)received dislled water; lead acetate at dose of 5mg/kg b.w (T1); ALA at dose of 60mg/kg b.w (T2) and and group T3 received both of PbAc + ALA at the same doses of above. Blood samples were collected at 0, 28 and 56 day of the experiment, then the sera were collected for determination of testosterone(T) and follicular stimulating hormone (FSH). At the end of the experiment, body weight, testes weight and epididymal sperm parameters was studied. Furthermore, histo-morphometric and histopathological study changes were examined. The results revealed a significant decrease in testes weight to body weight ratio, serum testosterone, sperm concentration and motility, diameters of seminiferous tubules, height of seminiferous epithelia and number of Leydig cells, moreover the results showed a significant increase in serum FSH, dead sperm and abnormal sperm morphology in group T1 when compared with the other groups. Comparing to lead acetate treated rats, group T3 showed an improvement at the level of the studied parameters, accompanied with mild congestion in the interstitial tissue with a marked developing proliferation of spermatogenic cells, as well as presence of mature spermatozoa in the seminiferous tubules. In conclusion, subchronic exposure of rats to lead acetate showed an amelioration of all reproductive parameters near to normal values due to the antioxidant effects of ALA and the histological changes of the testes confirmed such change in serum parameters and the beneficial role of ALA.

Toxoplasmosis is an important worldwide foodborne zoonotic disease. Infected cattle meats is considered a serous cause of human toxoplasmosis. Here, this study assesses the infection with Toxoplasma gonddi (T. gondii) in cattle using meat juice samples from diaphragmatic muscles collected at the slaughter. An in house indirect enzyme linked immunosorbent assay (ELISA), and commercial latex agglutination test (LAT) followed by immunoblotting were developed on the meat juice (fluids) using tachyzoites of locally isolated T. gondii strain. The comparative analysis of the results of the tested juice samples showed an excellent agreement between the in-house indirect ELISA and LAT test in the positive and negative of meat juice. Relative sensitivity was higher for ELISA on diaphragms fluids random samples 80.39%, for the LAT test was 68.6%. Immune-reactive bands of T. gondii local strain Ag with naturally infected meat juice were 116, 83, 65, 30 and 23 KDa. The obtained results concluded that the development of an effective ELISA test to be used in for detection of toxoplasmosis infection of slaughtered cattle in large-scale would be exactly valuable, since the important role that beef plays in epidemiology of T. gondii, in particular the hazard of transmission to human and food safety.

Escherichia coli O157:H7 is considered as an important pathogen of diarrhea in adult dogs and puppies because it contains virulence genes. The study objective was to the molecular detection of the rfbO157 encoding the O-antigen specific for E. coli O157: H7,shiga toxins and hemolysin genes of E.coli O157:H7 in feces of dogs that collected from different regions in Tikrit and Mosul cities, Iraq. One hundred fecal swabs were collected from pet and K9 dogs including (72 dogs with diarrhea, and 28 without diarrhea). All the Collected swabs were cultured in the nutrient and MacConkey agars, Then the suspected colonies were cultured in the EMB agar. Metallic sheen colonies were cultured by using the chrome agar. All bacteriological identified isolates were enrolled by using the polymerase chain reaction (PCR) technique. The results of this study showed that 7(9.7%) of 72 dogs suffered from diarrhea were positive for E. coli O157:H7 that contained the rfbO157 gene (n= 6), carry stx1 gene (n= 3), carry stx2 gene (n= 3), and hlyA gene (n= 1). On the other hand, 2 (7.1%) of 28 dogs without diarrhea were positive for E. coli O157:H7 that contained the rfbO157 gene (n= 1), stx2 gene (n= 1), and hlyA gene (n= 1). In conclusion, dogs can be a significant reservoir for pathogenic E. coli O157:H7, particularly dogs with diarrhea.

Neospora caninum was identified as a coccidian parasite as in 1988, before that date it was misclassified as Toxoplasma gondii based on structural similarities. The aim of this study was to determine theseroprevalence of N. caninum in cattle in Kirkuk Province. A total of 185 cattle serum samples were collected randomly. Data about ages, gender and abortion history of females were recorded. Serum samples were examined by using ELISA as a screening test for the detection of anti- N. caninum IgG antibodies of past infection. Results showed that 53 (28.6%) cattle were seropositive infected, with significantly higher seropositive infection of age group >2 years in comparison to other age groups 94.3%. The distribution of N. caninum of total infected cattle showed that the seropositive infection in females were 47(88.7%), which was more than males 6 (11.3%) with a highly significant difference. There were 22(48.8%) aborted cattle out of 47 infected cattle with N. caninum with no significant difference in comparison with the healthy group.

Abalone is one of aquaculture commodity that has a high value including in Indonesia due to its price, taste and nutrition content. Unfortunately there is problem in abalone’s transportation process which caused stress and even death. Clove oil can be used as anesthetic agent for abalone to obtain a high survival rate because of its eugenol content. This research tried to evaluate the the effect of clove oil as anesthesia agent to determined induction time, survival rate and oxygen cosumption in H squamata. This study used an experimental method and used a completely randomized design with treatment concentration of clove oil solution were 0.5 ml/L (A), 0.7 ml/L (B), 0.9 ml/L (C), and 1.1 ml/L (D) which each treatment was repeated three times, and calculated the value of the abalone (H. Squamata) survival rate after maintenance for 14 days. The results of the study showed that the survival rate of abalone seeds obtained in the treatment with the concentration of 1.1 ml/L (D). In the treatment also showed the fastest induction time with 96.67 seconds. The lowest oxygen comsumption rate in this study was treatment D with concentration of 1,1 ml/L. It could be concluded that using clove oil with concentration of 1.1 ml/L as anasthesic compound for abalone showed effectiveness in induction time, survival rate, and oxygen consumption rate.

Clinical and subclinical mastitis regarded as important diseases causes a reduction in reproductive performance in dairy cows in the UK during the last decade. This study was aimed to assess the association between clinical mastitis, subclinical mastitis and the reproductive performance of cows. Data from 184 multiparous Holstein dairy cows were collected. Binomial logistic regression used to determine the incidence rate of clinical mastitis and subclinical mastitis between parity, calving year and seasons of the year. Linear mixed model used to determine the effect of clinical and subclinical mastitis on reproductive performance. The association between clinical or subclinical mastitis and the probability of a cow to get pregnant at 1st, 2nd or 3rd service was evaluated using binomial logistic regression. The same model used to illustrate the probability of a cow getting pregnant from 30-60 days postpartum or 61-90 days postpartum. The incidence of clinical mastitis was different between calving years (P<0.01). Cow with clinical mastitis or subclinical mastitis had longer calving to first service interval, calving to conception interval (P<0.05). Cows clinical mastitis had a lower rate to get pregnant within 20-30 days postpartum compared to healthy cows (P<0.05). Cows with higher somatic cells count, (especially cows with greater than 399,000 cells/mL of milk), had a higher number of services compared to cows with a lower number of individual cow somatic cell counts. The study concluded that both clinical and subclinical mastitis have a relationship with a reduction in reproductive performance in high yielding dairy cows.

A cross-sectional study was carried out from November, 2015 to April, 2018 to determine the prevalence and identify the risk factors of BTB using the comparative intradermal tuberculin (CIDT) test on 5327 dairy cattle in 16 dairy herds in mid-delta, Alexandria Road and Upper Egypt districts. Questionnaires used to collect data on herd size and management. The herd and individual animal prevalence at cut-off ≥4mm were 68.75% (95%, CI: 46 to 91.4) and1.67% (95%, CI: 1.3to 2.1) respectively. The individual prevalence was significantly associated with age, breed and different location of farms and density of cattle in yard. On herd level, history of BTB in the farm, management practices, raising of different species in the same facility and newly purchased cattle are important risk factors for BTB. The postmortem examination of positive reactors revealed 66 (85.71%) out of 77slaughtered cattle with visible lesions and 11(14.29%) with non-visible lesions. Bacteriological examination revealed 74.24% (49/66) from visible lesions and 9.09% (1/11) from non-visible lesions were Mycobacterium bovis. The indirect enzyme linked immunosorbent assay (IELISA) results revealed 31(40.26%) showed positive result including 29 (93.6%) visible lesions and 2(6.4%) nonvisible lesions. In conclusion, the prevalence high in herds with poor management condition, raised different species in the same facility, had previous history of BTB infection and purchased new animals. At animal level Holstein breed, 3-6 years age, kept in high density and located in mid- delta district were at higher risk to be reactor to comparative intradermal tuberculin (CIDT) test.

The main purpose of this research is to evaluate the high level of thyroxine affects on each of the luteinizing hormone (LH), testosterone, follicle-stimulating hormone (FSH) of rats and to estimate the potential effect of the administration of aqueous rosemary extract and propylthiouracil against testicular toxicity induced by levothyroxine in male rats. Negative control group rats were treated with distilled water. Three groups of male rats were treated subcutaneously with 0.5 mg/kg levothyroxine for 12 days: Since day 13th to the 24th day of the experiment first group was regarded as a positive control group that received distilled water, the second group was given propylthiouracil at a dose level of 10 mg/kg b.wt, and the third was given aqueous extracts of rosemary 10 mg/kg b.wt. The results revealed that treatment with aqueous extract of rosemary lead to a significant decrease in the levels of serum testosterone while a highly significant decrease in testosterone, FSH, and LH levels in serum revealed after treatment with propylthiouracil. Thus, it can be concluded that the effect of propylthiouracil and rosemary aqueous extract resulted in dialectical hormonal results in which the favor was to propylthiouracil.

The significance of Aeromonas hydrophila concerning hemorrhagic septicemia in aquaculture farms production in Duhok province, Iraq was investigated. Antibiotic-resistant profiles of isolates were also investigated with 8 antibiotics. Bacterial isolates were identified by using morphological and biochemical tests and confirmed molecularly by amplification of gcat gene. Out of 25 examined fish, only 19 fish were harbored A. hydrophila. Twenty-four A. hydrophila strains were isolates from 100 organ samples. Ninety-six percentages of the isolates were resistant to each of the imipenem and gentamicin, followed by doxycycline 92%, ciprofloxacin and trimethoprim-sulfamethoxazole 88%, norfloxacin 58% and ceftriaxone 33%. None were resistant to levofloxacin. Eighty-eight percentages were multiple antibiotics resistant. The high isolation rate of A. hydrophila in our study indicates that this species was the major cause of the outbreak in hemorrhagic septicemia’s cases in our area affecting carp farms and the high rate of resistance should be considered as these isolates can serve as a resistance source for human being during food series and make a great challenge for their therapeutic opportunity.

Fresh semen from fifty bulls was evaluated for ejaculate volume, individual motility, concentration, lives sperm and abnormalities as well as acrosome integrity. Bulls were classified according to semen motility into two groups; good and poor. DNA was extracted from semen of both groups, then the PCR followed by single-strand conformation polymorphism (SSCP) techniques were performed for mutation detection in gonadotropin releasing hormone receptor (GnRHR) gene through multiple sequence alignment. The results showed that the percentages of sperm motility, sperm concentration and live sperm, were significantly higher in good than poor semen quality bulls. However, semen volume, percentage of acrosome integrity and abnormalities did not differ between good and poor. The PCR amplification of 240-bp fragment and the results of SSCP appeared a genetic polymorphism with two patterns. Pattern I was seen in all good bulls, with incidence of 100%. Pattern II appeared only in poor semen quality bulls with a frequency of 31.25%. The sequence analysis of the PCR product for the two patterns showed two single nucleotide polymorphisms (SNPs) as a transversion base substitution mutation at positions 20 (T/A) and 193 (A/T). The GnRHR gene could be used as a genetic marker related to semen quality in buffalo due to the good semen bulls had a unique pattern.

Baclofen has a central acting effect, so clinicians have been utilized it chiefly for treating the spasticity of spinal origin. Nowadays, off-labeling use of baclofen with high doses is frequently increased. Despite of the extensive research studies on the effectiveness of baclofen, the reports on its histological effects on testes and on sperm parameters we insufficient. This work aims to assess the histological influences of baclofen on rats' testes and on several sperm characteristics after administration for 8 weeks. Twenty-two male rats at age of peripuberty (8weks) that were categorized into two groups. Group I (control group) includes 10 rats which were gavaged with 1 ml/day of distilled water daily. Group II (baclofen's group) includes 12 rats which were received baclofen 14.5 mg/kg for 8 weeks via gavage. At the end of the designed work, euthenization was done and the testes were excised from each rat, the epididymis samples were obtained and prepared for examination under light microscope. This study revealed that rats that were administered with 14.5mg/kg/day of baclofen for 8 weeks showed changes in the sperms parameters with several testicular histological alterations in their sections in comparison with those of controls. The percentage of the live sperms of rats (baclofen's group was lower than that of control group). Features of sloughing inside seminiferous tubules' lumen are frequently seen among these sections with mild decrease in the diameter of seminiferous tubules. Evidence of decreased Johnsen's scores (spermatogenic index -SI) was noticed in some sections, and decreasing of the frequency of seminiferous tubules that possess spermatozoa was obviously noticed. Moreover, disorganization of seminiferous tubules is shown in these sections. In addition, sections of rats of baclofen group revealed features of necrosis of seminiferous tubules, presence of degenerated spermatogenic layer, features of apoptosis, and presence of gaps in the seminiferous epithelium of degenerated tubules. Different alterations of sertoli cells as vacuolation, and detachment sertoli cells are noticed in sections of rats that were administered with baclofen. The chronic administration of rats with 14.5 mg/kg with baclofen induced effects on sperm parameters and testicular histology. however, the testicular histological alterations were more obvious. Further works are needed to clarify mechanism that stands behind these effects.

Extended spectrum β-lactamases producing Enterobacteriaceae (ESBL-E) have emerged recently as the main cause that facilitates the spreading of antibiotic resistance worldwide. Due to its composition and nutritive values, raw cow milk is vulnerable to bacterial contamination from different sources, especially ESBL-E. Accordingly, present study aimed to detect the ESBL-E in the raw milk of healthy cows. 80 raw cow milk samples were collected from unorganized farms and cows belong to individual owners and investigated for the presence of ESBL-E with the main focusing on CTX-M type. The bacterial isolation was performed using selective MacConkey agar plus cefotaxime (MC+), while PCR was used to confirm the species of the isolated bacteria and presence of CTX-M gene. The results showed that 28.75%(23/80) samples were ESBL-E positive and distributed as following, 82.61%(19/23) were pure E. coli isolates, 4.35%(1/23) was pure K. pneumoniae isolate and finally, 13.04%(3/23) were mixed of both E. coli and K. pneumoniae isolates. Moreover, the total number of positive ESBL-E was 26 isolates with the majority of them were belong to E. coli and recorded 84.61%(22/26), while K. pneumoniae was recorded less 15.39%(4/26). Additionally, the CTX-M gene was successfully identified in all ESBL-E positive isolates by using PCR, including E. coli and K. pneumoniae isolates. The results of this study assert the importance of raw cow milk as a potential source of ESBL-E that might be transmitted to humans.

This study was aimed to determine the prevalence of rotaviruses in Karbala and Basrah provinces, the genetic reassortment of human and animal rotavirus strains and the novel strains. Rotaviruses were detected by Immunochromatography Test (ICT) then the positive samples were tested by reverse transcription PCR (RT-PCR) using specific primers to VP7 gene, this gene is responsible for VP7 antigen which is responsible for stimulation the immune system to produce neutralizing antibodies. The VP7 gene was implemented in rotavirus vaccine of Iraqi immunization program. The RT PCR results showed that 56.3% (27/48) of samples positive in children under five years of age in Karbala province while Basrah province revealed 58.5% (31/53) positive samples in children whereas samples taken from calves revealed 43.1% (22/51) and 45.5% (25/55) positive samples in Karbala and Basrah provinces respectively. The sequencing of human and animal samples revealed that there was genetic reassortment between human and animal strains while in comparing with international strains there was closely related with Indian and Pakistani human strains. Necessarily for further bioinformatics studies are needed to study the genetic alterations with viral proteins analysis of rotavirus.

One-humped camels (Camelus dromedarius) are important source of meat, milk and leather production for humans in southern Algeria. Camel livestock farming is confronted with several obstacles, including abortive diseases which can be transmitted mainly by ticks. The study was carried out in Ouargla region, South Algeria, between January and December 2017. The objective of this study was to identify ticks in camels and to study the relationship between camel abortion rate and the presence of different species of ticks. A total of 350 camels (including 171 males and 179 females) was used in this study. Ticks were searched on the entire camel body (head, neck, hump, abdomen, forelegs, back legs, and tail area). Results showed that 215/350 (61.4%) camels were infested by ticks including 137/171 (80.1%) and 78/179 (43.6%) males and females, respectively. A total of 46/179 (25.7%) camel females had aborted and all these were revealed infested by ticks. A total of 298 ticks was collected including the following species Hyalomma dromedarii (90.9%), Hyalomma impeltatum (5.37%) and for the first time in Algeria, Amblyomma variegatum (2.35%) and Rhipicephalus turanicus (1.34%). H. dromedarii was the most frequent (p<0.001). The study showed that the dromedary was highly infested by ticks. The presence of ticks in all aborted female camels certainly indicates their important role in one-humped camel abortions in Algeria. The identification of tick-borne abortive agents in camels is important in order to establish an effective abortion control plan.

This study was conducted to determine the genetic variation of the prolactin (PRL) gene in 5' flanking region and its role with several reproductive traits in Awassi sheep. One-hundred six Iraqi sexually mature and healthy Awassi ewes that aged between 2 and 2.5 years were included in this study. Ewes were classified into two the main divisions: ewes producing twins and ewes producing single offspring. Two genotypes (AA and AT) were observed in Awassi sheep. While genotype AA was detected in Awassi ewes that produced twins, genotype AT was detected in ewes that produced a single offspring. The sequencing reactions identified nine SNPs in the prolactin gene at the 5′ flanking region in Awassi sheep, differing from the prolactin reference sequence (GenBank accession number X16641.1). Genotype AT possessed one single nucleotide polymorphism SNP substitute comparison with the AA genotype in Awassi ewes. The association analysis revealed that the AA genotype is characterized by significantly higher levels of the progesterone concentration, twinning ratio, fecundity, and prolificacy than the AT genotype. In conclusion, a new SNP (g.1209 A>T) was discovered within the ovine flanking region which potentially influences prolactin gene expression. These results showed that the genotype AA associated with high prolificacy of Awassi sheep may be used as a selection criterion for improving the reproductive performance of Iraqi Awassi sheep.

This work was aimed to explore the details of the ion channels gating and there physiological role in sperm in the future.Mouse spermatozoa express a pH-dependent K+ current (KSper) thought to induce hyperpolarization to enhance Ca2+ influx via alkaline-activated calcium channel (Catsper) to initial a so-called sperm capacitation by NH4Cl during travelling in female genital tract for fertilization. However, the regulating mechanism of the Ksper and Catsper channels by membrane potential and pHi remains uncertain, because the complexities of two channel kinetics in sperms is hardly to be overcame at this stage. Here we show that difference of the intracellular [Ca2+]i between the wild type (Wt) and knockout (KO) Ksper (or Slo3/) mice in the application of the Slo3 blockers, Guinidine (QD) and Clofilium, and NH4Cl, indicating that Ksper channels, encoding Slo3 gene, dominates the membrane potential of mouse sperms to increase the intracellular [Ca2+]i and [pH]i during the capacitation process to play a vital role in fertility. Furthermore, a HH model sperm built directly with the native Ksper and Catsper currents in sperms reveals two functions of membrane potential and intracellular pHi, allowing us to calculate the intracellular pHi by NH4Cl, based on membrane potentials recording from current-clamp experiments. During modeling, we found a caton channel with Vrev= +20 mV in mouse sperm from the double-KO (i.e. Catsper-/- and Ksper-/-) mice, which is definitely necessary for a model able to match the data.

The disaccharides, consisting of sucrose, lactose and maltose, are hydrolysed into monosaccharides (D-glucose, D-galactose and D-fructose) by intestinal brush border enzymes: sucrase, lactase and maltase. The aim of this study to investigate changes in the brush-border membrane carbohydrate digestive enzymes. From intestinal mucosal scrapings of equine, brush border membrane vesicles were isolated. The results showed that sucrase, maltase and lactase are present in the equine small intestine. The activity of all three enzymes is highest proximally (in the duodenum and jejunum) and lower in the ileum. There was considerable variation between individual horses, however the majority showed highest disaccharidase activity in the jejunum, with some showing highest activity in the duodenum. Sucrase activity is highest in the jejunum and duodenum and lower in the ileum. Maltase activity is similar in all three regions, but slightly higher in the jejunum. Lactase activity is low in all three regions of the small intestine, slightly higher in the equine jejunum and duodenum than ileum. From this study, we can conclude that the equine small intestine digests disaccharides by the brush-border associated disaccharidases sucrase, maltase and lactase. Levels of sucrase and lactase are comparable to other species, but maltase is much higher.

The present study was aimed to determine the scolicidal effect of stem and root alcoholic extract of Punica granatum L. (Pomegranate) on the viability and fatty acids content of Ecinococcus granulosus protoscolices. The study elucidate the scolocidal effect of both stem and root extracts. Its seemed that the scolocidal effect of root extract was higher than that of stem extract ie. LC50 and LC90 of stem extract were 5 and 9 mg/ml respectively while LC50 and LC90 of root extract were 3 and 8 mg/ml respectively. GLC analysis of E. granulosus protoscolices was stated presence of nine fatty acids esters, which were Lauric (C12:0); Myrisitic (C14:0); Palmatic (C16:0); Stearic (C18:0); Archidic (C20:0); Behenic (C22:0), which were saturated fatty acids, and Oleic (C18:1); Linoleic (C18:2); Linolenic (C18:3) which were unsaturated fatty acids. Treating E.granulosus protoscolices with LC50 of pomegranate stem bark was showing slight and swing effect on fatty acid content, while treated the protoscolices with LC50 of root bark were resulted in obvious increase in short length fatty acids like Lauric, Myrisitic and Palmatic in compare with control group. In contrast the long chain fatty acids concentration like Oleic, Linoleic and Linolenic were decrease.

Pseudomonas (P.) aeruginosa possesses a variety of the virulence factors that may contribute to its pathogenicity, such as exotoxin A (toxA) and exoenzyme S (ExoS). The principal aim of this study was to find out the rapid method for identification of P. aeruginosa and to detect the toxA, exoS and16SrRNAgenes by Polymerase Chain Reaction (PCR) technique. Other aim on the other hand, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local pathogenic P. aeruginosa isolates in comparison with NCBI-Genbank global P. aeruginosa isolates and finally submission of the present isolates in NCBI-Genbank database. According to the detection of the 16S rRNA gene, the study revealed that 29 (58%) and 32 (64%) of P. aeruginosa out of 50 swabs obtained from each wound and burn areas were positive. whereas in addition, the result of this study showed that the toxA gene was detected in 77% of P. aeruginosa isolated from the wound and 51% of P. aeruginosa isolated from the burn. whereas, the exoS gene was detected in 69% of P. aeruginosa isolated from the wound and 49% P. aeruginosa isolated from the burn. BLAST analysis showed that the 16S rRNA gene shared more than 99% homology with the sequences of P. aeruginosa. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that (PA-IQw and PA-IQb) the 16S rRNA gene shared higher homology with other four P. aeruginosa isolates available in the GenBank. The homology of the nucleotides was between 99.9% and 100%.

Research was undertaken to establish an inventory of ticks on dogs in the north east of Algeria. In the first aspect of study, a survey aims to identify of Ixodidae infesting the dogs in bioclimatic different areas and to determine the risk factors. This work took place between 2006 and 2012. The results of the collections show that all the dogs, which were the subject of this survey, are infested by ticks during the period between March and August in different areas of the northeastern of Algeria. Rhipicephalus sanguineus is the predominant tick species. It has been observed with a frequency of 88 % in the area of El-Tarf, 100 % in Souk-Ahras, 95 % in the Tébessa region and 72 % in Guelma, (average of 89 %). Climatic conditions seem to play the essential role for this distribution of ticks. The other tick species collected are: Ixodes ricinus, Rhipicephalus turanicus, Haemaphysalis punctata and Hyalomma anatolicum. The latter were present with very low a proportion, which gives them the appearance of accidental parasitism in dogs. Rhipicephalus sanguineus has significant infestation intensity in spring and summer, peaking in August in the semi-arid region (Souk-Ahras). In humid regions (El-Tarf), the peak of infestation recorded by this arthropod is in April. The second aspect of study of the seasonal dynamics of Rhipicephalus sanguineus shows the seasonal nature (Spring-Summer) of the brown tick of dog.

The aim of this work is to study lamb births and mortalities in Algerian sheep Ouled Djellal breed distributed in different zones of Tébessa region, which is divided according to bioclimatic stage, staff in livestock and area agricultural vocation, into four distinct zones: northern (A, B), middle (C) and southern zone (D). During two years 2015-2016, birth numbers (BN) and mortality rates (MR) of 355 sheep flocks were recorded using a questionnaire. Concerning BN the total number was 21244 lambs representing a mean 59±31 per flock. No significant differences between the birth means of C and D (75±28 vs 83±30) were registered. Birth mean was significantly higher (P<0,05) in B (40±17) than A (29±10), when comparison with C and D, the births of A and B were highly significantly (P<0,001). According to (BN) the studied region were classified into 3 zone groups: (a) with high lambing rate (C, D); (b) with medium lambing rate (B); (c) with low lambing (A). In regard to mortality rates, the total rate was 24±6%. The (MR) in A (27±5%) was significantly higher (P<0,05) as compared to other zones (B) 24±4%, (C) 23±7% and (D) 22±4%. However, no significant differences between B, C and D were revealed. According to the results of (MR) the studied region was classified into two groups: (a) with low MR (C, D), (b) with high MR (A, B). Our result showed that zones influence the (BN) and (MR) in Tébessa region, and southern zones especially D seems the appropriate to practice breeding of Ouled Djellal breed.

This study aimed to investigate the impact of supplementing different levels of Nigella sativa oil in rations of growing lambs. In a feeding experiment lasted 90 days, 18 growing Ossimi lambs (6-7 months old) were randomly divided by weight into three equal groups (6 animals each). Individual animals in all groups were fed a uniform total mixed ration, offered at 3% of body weight, where the first group was without supplement (R1), while Nigella sativa oil was supplemented at 0.1 (R2) and 0.2% (R3) of dietary DM. Results indicated that additions of N. sativa oil didn’t influenced feed intake, but it increased average body weight gain and feed efficiency. Nutrients digestibility values and dietary nitrogen utilization were higher with N. sativaoil rations than control. Ruminal fermentation parameters showed comparable pH values among groups at 0, 3 and 6 hrs. of feeding. Ruminal NH3-N concentration was lower and TVFA concentration was higher for animal fed R2 and R3 rations than control. It’s concluded that N. sativa oil could be added at 0.2 % of the daily feed as a natural growth enhancer of lambs.

COVID- 19 is highly infectious disease where the first infected case reported in Wuhan city-China, then it was spread worldwide. The causative agent belongs to novel enveloped single linear positive-sense stranded RNA Coronavirus, which is also called SARS-CoV-2 and has an affinity to lung cells. The genetic analysis of SARS-CoV-2 suggested that this novehtm hgn l strain may be developed from the animal. origin by recombination between a bat SARS-like CoV and a coronavirus of unknown origin. The ability of rapid spread of SARS-CoV-2 virus from person to other is similar or even more than to other human viruses like influenza or plague leadding to be announced as a pandemic by WHO in 2020. The mortality rate in SARS-CoV-2 increased day by day and this led the scientists to search ways to control the virus. Most of the deaths in aged patients may be due to immune response complications where 70% of patients showed lymphopenia. This review, provided some details about structure, pathogenicity and immune response against SARS-CoV-2. The facts in this review lead to suggest that in most cases the death in SARS-CoV-2 may occur via loss of systemic inflammatory response control which leading to lung injury followed by pneumonia, acute respiratory distress syndrome (ARDS) and respiratory failure, hence the death especially in old patients. In concluding the early effective control of both innate and adaptive immunity may be the critical. key factor in protection against SARS-CoV-2.

The present study was conducted on 57 local breed cows suffering from various degrees of endometritis. The clinical examination included visual examination of vagina supported by uterine palpation per rectum; the laboratory examination included the bacterial isolation from the uterine swabs and histopathological examination of the uterine biopsies. Animals were randomly divided in to three groups of 15 cows each and 12 cows were considered as a control group received no treatment and observed for three consecutive estrous cycles. The first group was treated with a mixture of oxytetracycline (4 g) and tylosin (2 g), second group was treated with cephquenome sulfate 0.5 g, and the third group was treated with lugol's solution (30 ml) 2 %. These treatments were applied as a single intrauterine infusion and the clinical recovery was evaluated at the next estrous cycle by considering the absence of abnormal vagina discharge as an indicator of clinical recovery. Cows that showed clinical cure were inseminated artificially and the pregnancy diagnosis was preformed at least 75 days after insemination by rectal palpation. Retained placenta was the most important predisposing factor of endometritis 50.8 %, results of the bacterial examination demonstrated that E. coli was the most prevalence bacteria (27.4 %). Histopathological examination of uterine biopsy showed a high incidence ratio of chronic endometritis (42.1 %). Results of the treatment showed a higher response and conception rate in the second group (using of cephquenome) 73.3 % and 63.3 %, respectively, followed by first group (using mixture of oxytetracycline and tylosin) 60 % and 55.5 %, respectively, then the third group (using of lugol's solution) 40 % and 50 %, respectively. The lowest cure and conception rates were observed in the control group 25 % and 33.3 %, respectively. This study pointed out a positive relationship between the nature of the vaginal discharge and each of the bacteriological and histopathological examination and revealed the importance of the early treatment of endometritis especially using of cephquenome sulfate.

A total of 1116 records Awassi ewes and 432 of Hamdania ewes were collected and which belong animals resource department, Faculty of Agriculture and Forestry at the University of Mosul for the years 2008, 2009 and 2010 to study the effect of genetic and non-genetic factors in milk production and some of its components from birth until weaning. The results showed significant effects (p≤0.05) for the breed and highly significant effects (p≤ 0.001) for the year, mother's age, sex, and type of birth in the daily milk production. There was a highly significant effect of year in milk fat, protein, and lactose. same there was a significant effect for age at weaning on birth weight, and highly significant effects for the breed, year, age of dam, sex, type of birth, and age at weaning on birth, weaning and weight gain from birth to weaning. The highest value for repeatability was 0.398, 0.309 in Awassi ewes for weight gain and in Hamdani ewes for daily milk yield respectively. Phenotypic and genetic correlation between protein and lactose in Awassi ewes 0.507 and 0.410, and in Hamdani ewes 0.641 and 0.157 respectively were highly significant.

The prevalence of suppurative arthritis in one hundred sheep from both sexes and different ages were studied. Aspiration of synovial fluid from knee joint of animals showed signs of lameness with reluctant to move in addition to decrease in the body weight and loss of appetite. Physical and bacterial examination of the synovial fluid was revealed green color, turbid and containing pus. Mucin clot showed difference in degree of clotting, and increased number in leukocyte, neutrophile but decreased in lymophocytes and monocyte. The result showed that Streptococcus dysagalactiae was predominate 61.1% while Arcanobacterium pyogenes and Pseudomonas aeruginosa were the less 5.5%, also the result showed that all the strains were more sensitive to the Ciprofloxacin. This study is considered to be the first attempt to isolate bacteria from Sheep joints in Mosul-Iraq.

DOI: 10.33899/ijvs.2008.5664

Data of twenty one local breed bull calves (Sharabi and Janoubi) were collected from previous work for this study, their ages ranged from 8-18 month with initial live body weight of 125-300 kg. They were fed for 100 days period a standard ration which consisted of 60:40% concentrate to roughages ratio and contained 12.4% crude protein, 19.9% crude fiber and 2.2 Mcal/kg ME. Feed was offered at 3% of live body weight. Calves weights were sorted out into three groups, according to their means of body weight and were 140, 210 and 280 kg. The first group of calves had a significant increase daily gain more than the other two groups and were 1200, 850 and 830 g, respectively. Also, feed conversion rate of the first group was better than the other two groups, and were 6.2, 8.9 and 9.9 kg. ration/1 kg weight gain, respectively. Cost of feeding to produce one kg of weight gain in the first group was more efficient than the other two groups, and were 1860, 2670 and 2970 I.D., respectively. No differences were found in carcass traits among the three groups of calves. The results of this study suggest that it is better to choose local bull calves at live weight less than 200 kg for fattening purpose, to obtain more economical benefit.
