In an attempt to find a treatment for diabetes by Placental mesenchymal stem cells, we induced diabetes in albino mice by injected them with the diabetic agent Alloxan intra peritoneal cavity dose 70 mg / kg of body weight for the group 1 and 2, then injection of the diabetic mice with Placental mesenchymal stem cells in the peritoneal cavity for the group 2 then the glucose levels in the blood of these mice were measured by using a GLUCOTREND 2, while group 3 was control injected with normal saline only. Pancreas tissue where tested by studying histopathological effect of Alloxan, the endocrine pancreas histologically showed decreased in the size and number of Langerhans islets with vacuolar degeneration and necrosis of almost all cells in the atrophied islets. Also, there was congestion of blood vessels in the interlobular space and there was distortion of exocrine pancreas. There was vacuolar degeneration and necrosis of the epithelial cells of the acini, also there was atrophy of acini which lead to edema and dilatation of interacini space. Moreover, there was thickening in the wall of blood vessels, and there was thrombus in some blood vessels.
In addition to the infiltration of inflammatory cells in the interlobular septa. Compared with the section of pancreas of control group showed the normal structure of islets notice the normal cells shape surrounding by exocrine pancreas. Then the pancreas studied after injection of Placental mesenchymal stem cells, while there was regeneration of islets and acini which seem to be normal comparing with control group, there was improvement of normal histological appearance of mice treated with alloxan and then injected with placental mesenchymal stem cells. The results of the diabetic mice which treated with placental mesenchymal stem cells demonstrated present of significant differences (P≤0.05). Our conclusion of this study revealed that placental mesenchymal stem cells have a protective role against the histological changes of pancreas induced by alloxan.
The present study was intended to determine the histological changes induced by Cytarabine drug on the structure of rabbit's livers and the protective effects of vitamin E on these histological changes. The treated group with daily intraperitoneal dose of (50 mg/kg body weight) of Cytarabine alone, showed a massive histological change represented by infiltration of mononuclear inflammatory cells, epithelioid cell and Kupffer's cells in hepatic tissue. Fibrosis in portal area, congestion of blood vessels as well as hyperplasia of bile canaliculi and coagulative necrosis of hepatocytes were also noticed in other sections. While the group that received protective (800 IU of vitamin E) prior to each Cytarabine injection, showed a considerable histological improvement than the group received Cytarabine alone, as the histological sections of this group showed a nearly normal histological architecture of the liver that represented by normal arrangement of hepatic cords, no fibrosis no congested blood vessels were seen. though distension of hepatic sinusoids and coagulative necrosis of some hepatocytes were still observed. The present study suggested that vitamin E is an effective chemo-protective agent against hepatotoxicity when used as a protective agent prior to Cytarabine drug taken.

Haematological changes, oxidative stress markers and electrolyte alterations were evaluated in puppies infected with canine parvovirus type 2 (CPV-2) that were presented to veterinary hospitals and clinics in South Eastern, Nigeria. Fifty-one dogs were used for the study and they were assigned into three groups. Group I consist of 21 diarrhoeic dogs naturally infected with canine parvovirus, groups II, were 15 diarrhoeic dogs uninfected with canine parvovirus and group III, were 15 apparently healthy dogs which served as the control. Immunochromatographic (IC) test was used to screen the dogs for canine parvovirus type 2 infections. The mean red blood cell (RBC) counts, packed cell volume (PCV) and haemoglobin (HB) concentrations were significantly lower in the diarrhoeic infected than diarrhoeic non-infected and the control groups. The mean catalase (CAT) of diarrhoeic non-infected group was significantly lower than diarrhoeic infected group and the control. The mean malondialdehyde (MDA) of both diarrhoeic infected and diarrhoeic non-infected groups were significantly higher than the control. The mean serum sodium (Na+
) level of the diarrhoeic non infected group was significantly lower than the diarrhoeic infected group. The mean serum potassium (K+
) level was significantly lower both in diarrhoeic infected and diarrhoeic non-infected groups compared to the control groups. It was therefore concluded that the levels of oxidative stress and electrolyte alterations may not be affected by the origin or aetiology of a disease (CPV-2), but on the severity of the infection.

Toxoplasmosis is very important zoonotic disease in the world cause by an obligate intracellular protozoan parasite called Toxoplasma gondii
can infect human and all warm-blood animals, beef consider from most important source for infection with T. gondii
and there is no really data and study about the rate of the infection in beef in Al-Diwaniyah province, so for this reason the aim of this work was designed. A total of 300 samples which collected from heart, tongue, muscles, of 100 slaughtered beef of local and imported cattle, throughout the period from September 2017 to May 2018, initially examined microscopically for searching on T. gondii
bradyzoites then all suspected samples was subjected to conventional PCR technique through B1
gene amplification to confirm the infection, in addition to analyzed the recorded data for each sample to determine the effect of some factors on prevalence of infection like organ, season and animal age. Out of 300 tested samples only 53 were confirm positive T. gondii
DNA. The infection in local beef was higher (22%) than in imported (13.5%), while there is no difference in infection among different examined organs. Regarding to effect of some factors, the autumn season recorded highest rate of infection with significant differences rather than others seasons in both local and imported beef, whereas, age appears with no effect on infection. The local cattle meat is riskier than the imported due to the higher rate of infection with T. gondii
, and the animal age cannot affect on the infection rate, in comparing with the season which play role in this rate.
This study was conducted for diagnosis and description of the pathological changes of AIV-H5 as the causative pathogen in Iraqi broiler farms. The current study was carried out on 84 broiler farms. Infected birds were tested for detection of the AIV infection from the tracheal swabs by rapid chromatographic AIV type A and H5 test kits. In RRT-PCR 8 samples (8 farms) of Trachea were selected to be tested by this assay. Samples of trachea, lung, and spleen from the dead birds with natural AIV-H5 infection were submitted for histopathological examination. seventy-two out of 84 farms tested for AIV-Type A gave positive results, and 58 out of 72 positives for type A-AIV gave a positive result for H5 antigen in a rapid chromatographic strip. The main gross lesions in the trachea of infected birds were severe congestion and hemorrhage. In the RRT-PCR assay, 8 out of 8 samples gave a distinct positive result for this test. The microscopic histopathological examination of infected tracheas showed obvious desquamation of lining epithelium with complete loss of cilia associated with congestion of blood vessels in lamina properia. Infected lungs revealed diffuse alveolar damage and severe multifocal vascular congestion. There was deposition of fibrinous material in the splenic tissue associated with the disappearance of the germinal centers. Thus, we concluded that AIV-H5 infection causes severe pathological and histopathological changes as a result of systemic infection. The RRT-PCR assay was highly sensitive and specific for the detection of highly pathogenic avian influenza virus subtypes.

The present study was conducted to estimate the incidence, clinical findings, cytological and histopathological characteristics of spontaneously occurring skin neoplasms in dogs. A total of 40 grossly suspected cases of cutaneous and subcutaneous tumors were gathered during the period from July 2016 to August 2018 from male and female dogs in Baghdad city. Dogs with skin neoplasia revealed various clinical signs, and their ages were older than 5 years to 15 years. German shepherd 30% followed by Terrier dogs 25% were more influenced than other breeds. Concerning tumor features, the majority of neoplasms had solitary lesion 70%, regular shapes 65% with black color 55%. The tumors frequently occurred on fore-limbs and abdomen, and 80% of them lasted for 1-6 months. Cytological examination was valuable for initial evaluation of benign and malignant tumors. Its results were confirmed by the histopathology, in which the majority of neoplasms sized more than 5 cm and grade I. Nine different types of skin neoplasms were recognized, while 65% of them were malignant, the others were benign. Squamous cell carcinoma and adenocarcinomas were the most common comprising 35% and 25%, respectively.
The heat shock protein 70 (HSP 70) has important roles in protecting cells and keeping them alive when exposed to different stress conditions. The polymorphism of the hsp 70
gene could be linked with the ability of stress tolerance. This study aimed to determine the polymorphism of the hsp 70
gene in Iraqi buffaloes and study bits effects on the resistance to stress. This study was conducted during from November 2018 to February 2019. The number of buffalo females used was 35 at the age of 4 - 6 years, which belonged to the local farmers from Basra city, Iraq. The DNA was extraction from the blood samples then the polymerase chain reaction (PCR) amplification was performed. The DNA sequences were analyzed by using bioinformatics analysis. The results of the molecular analysis showed that there were two groups of the hsp 70
gene as a compare with the same genes in GenBank due to silent and missense mutations. Based on these findings, it can be concluded that the Iraqi buffaloes have adapted to the surrounding environmental conditions as a result of the action of HSP 70 proliferation. The hsp 70
gene was a useful biomarker of stress tolerance in buffaloes.

in sheep of Nineveh governorate. One handed and thirty-six sheep heads were examined for the presence of coenurus cysts 31 (22.8%) were infected. The younger were more affected than the adults. There were no significant differences between the number of infected males and females. The clinical signs varied from one animal to another which consisted of neurological disorders manifested by depression, bending of the head to one side, walking in a circular movement and paralysis in the hind limbs, while some animals did not give the clinical symptoms despite the existence of cyst. The number of cysts were ranged from 1 to 4 cysts/animal. The size of these cyst was ranged from 0.5 to 4 cm, and the volume of fluid in these cysts were ranged from 1 to 6 ml while the number of protoscolices in the cyst were ranged from 60 - 360 protoscolex, the mean length of large and small hooks was 179.95 µm respectively. The study also considered the identification of some chemical constituents of fluid of coenurus cyst such as glucose, total protein, cholesterol, triglycerides, calcium, sodium, potassium, urea and pH.
This study was performed in isolation of some pathogenic fungi from milk of apparently healthy cows. Eighty milk samples were collected from four quarters of twenty cows in the Abu Ghraib. Each sample was cultured on Sabouraud dextrose Agar at 28±2 ºC for 4-7 days. The most predominant mold and yeast were Acremonium
spp. and Rhodotorula
spp. that had used in the experimental infection. The number of experimental mice used in this study was 30 which divided into three equal groups. The 1st
group was infected with Acremonium
spp. by injection of 0.2 ml of 2*107
conidia/ml intraperitoneally. The 2nd
group was inoculated with same dose and route with Rhodotorula
spp., while the3rd
group served as control group. All mice were sacrificed after 2 weeks of injection, Serum was obtained for biochemical analysis of hepatic and renal enzymes. Some of internal organs of infected groups were taken for histopathological study. The result recorded that the total percentage of fungal infection was 53 (66.3%) of these Acremonium
spp. 9 (24.3%) and Rhodotorula
spp. 7 (43.8%). Histopathological sections of the 1st
group showed severe lesions in kidney than 2nd
group although both groups showed lesions in most internal organs. Blood biochemical results showed the yeast has highest significant differences on ALT levels, while the mold has highest effect on serum creatinine, with insignificant difference on urea. In conclusion it could be said that in spite of Acremonium
spp. and Rhodotorul
a spp. are considered as contaminant fungi, but they can cause disseminated mycosis in mice.
The present study was carried out to determine additional chewing lice of aquatic birds and additional data on the prevalence of chewing lice in aquatic birds found on the Southern marshes of Iraq. Sixty-nine of different species of aquatic birds were randomly collected and examined for chewing lice in Al-Sanaf marsh, which is located in Thi-Qar province / Southern Iraq, between October 2016 and February 2017, the lice placed in tubes containing 70% ethanol after that they cleared, mounted and identified according to morphological features. Twenty-five (36.23%) out of 69 aquatic birds were infested with chewing lice, a total of six lice species were identified from birds in the current study included Piagetiella titan
and Pectinopygus forficulatus
infested White Pelican Pelecanus onocrotalus

and Rallicola parani
infested moorhen Gallinula chloropus
. Three lice species: Pectinopygus forficulatus
, Rallicola fulicae
and Rallicola parani
were recorded in current study for the first time in Iraq. We need further investigations of Phthiraptera fauna are very important, not only to complete the list, but also to provide information about parasite-host vector relationships and phylogenetic relation among species.
The current study was conducted to investigate the effects of dietary supplements of organic acid and essential oil Gallant+®
on the growth hormone, glutathione, performance of growth, some biochemical parameters and intestinal histomorphology in quails. Japanese quails one-day-old (n=120) were distributed randomly into four groups included 10 / 3 replicates for each group. The G1, was control group that was fed on a basal diet. Quails of G2, G3, and G4 were fed on a supplemented diet Gallant+®
300, 600 and 900g/ton,respectively. Administration of Gallant+®
600 g/ton and 900g/ton to quail led to significant decrease in triglyceride while supplementation with 600 g/ton caused decrease in cholesterol. On the other hand, 300 g/ton caused an increase in final body weight and total weight through the duration of the experiment, as well as a decrease in total feed consumption and the best feed conversion ratio in all supplementation with 300 g/ton caused a significant growth hormone elevation. All feed additives didn't affect the level of glutathione. The addition of Gallant+®
additive groups. Interestingly, the addition of different doses of Gallant+®
to the diet increased villus length and width, crypt depth, villus / crypt ratio, percentage of goblet cell, apparent surface area, and intestinal epithelium thickness compared to the control group. It was concluded that dietary supplementation with different doses of Gallant+®
improved growth hormone, growth performance and intestinal histomorphology in Japanese quails, and dietary supplementation with organic acid and essential oil as alternatives to the growth promoter of antibiotics.
The aim of the present study was to determine the acute toxicity of chlorpyrifos and deltamethrin in mice separately and to study their toxic and neurobehavioral effects. Median Lethal Doses (LD50
) of chlorpyrifos and deltamethrin were determined depending on up and down method. The oral LD50
of chlorpyrifos was 193.05 mg/kg and of deltamethrin was 15.71 mg/kg in mice. The oral administration of chlorpyrifos 155 mg/kg and deltamethrin 12.56 mg/kg represent 80% of LD50
resulted in acute signs of poisoning that manifested by dyspnea, salivation and lacrimation at 100%, piloerection, straub tail, tremors, convulsions and death at 70% for chlorpyrifos and 60% for deltamethrin and writhing reflex at 20% for chlorpyrifos. Oral administration of chlorpyrifos 310 mg/kg and deltamethrin 24 mg/kg increased severity of toxicosis signs as a percentage of piloerection, straub tail, tremors, seizures and death 100%. As well as decrease the onset of tremors, convulsions and death, writhing reflex which appears at 20% for chlorpyrifos and 10% for deltamethrin. After three hours of chlorpyrifos and deltamethrin oral administration at doses represent 20% and 10% of LD50
there are significantly hypoactivation in open-field activity, significantly increased in the duration of negative geotaxis performance, significantly decreased in head pocking and swimming scores compared to control group. In conclusion we found that deltamethrin was more toxic than chlorpyrifos this is based on the LD50
value. However, the signs of toxicosis and neurobehavioral effects produced by both toxicants were not differential and could not be associated with the toxic level.
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 use of antibiotics in inappropriate on food producing animals can lead to resistance many of the pathogenic bacteria to the various types of antibiotics, one of which is the Escherichia coli
) which produces extended spectrum β-lactamase (ESBL). Antibiotic resistance in animals and humans has become a global problem that needs attention and immediate management by using specific antibiotics that used for therapeutic the infected animals. The aim of this study was to isolate and detect E. coli
producing ESBL. All E. coli
from the surface of dairy cow rectal swabs in Sendang District, Tulungagung Regency, Indonesia using the Vitek-2 method. The number of rectal swab samples used in the present study was 50. The results of this study showed that all the samples were suspected of being E. coli
, based on the morphological growth of colonies on the EMBA media. The isolates were identified by using the biochemical tests. All the samples were positive. In this study the double disc synergy test (DDST) method was using to confirm the ESBL. The antibiotics were used amoxicylyn-clavulanate, ceftazidime and cefotaxime for DDST. In additional ESBL confirmation test was used the Vitek-2 method. The presence of ESBL producing by E. coli
isolated from rectal dairy swabs in tulungagung was 6% (3/50).
This study aimed to assess the level of testicular damage by observing the changes in the diameter and epithelium thickness of seminiferous tubules in rats that exposure to nicotine per inhalation. Thirty adult male rats were used and divided into five equal groups and treatment as follows for 20 days; Control group NaCl 0.9%, P1 nicotine 0.5 mg/kg, P2 nicotine 1.0 mg/kg, P3 nicotine 2.0 mg/kg and P4 nicotine 4.0 mg/kg. All groups were given treatment per inhalation for twenty days. At the end of treatment and the rats were sacrificed testes were collected for histopathological preparation. The testes were processed for routine paraffin embedding and staining and the sections were examined for histopathological changes. There results showed that nicotine administration induced varying degrees of structural damage to the seminiferous tubules, as the decreased in diamater and epithelium thickness of seminiferous tubules. The diameter and epithelium thickness of seminiferous tubules in four experimental groups reduced compared to the control group. This study proves that nicotine administration does decreases the spermatogenesis of rats by reducing the diameter and epithelium thickness of seminiferous tubules in testes. It also proves that the level of testicular damage is directly proportional to the dosage of nicotine administrated to male rats.
This study was conducted to investigate the prevalence of mange in sheep in Anbar province by examining 462 heads of sheep. The disease was diagnosed by examining the skin scraping taken from the infected animals in the laboratory. The results showed that sheep were infected with Sarcoptes scabiei
parasite, and the total infection rate was 34.6%, and no significant difference was recorded between males 34% and females 35.2%, the highest rate was recorded in the month of January %56 and the lowest in the month of August 13.1%, and the highest rate of infection was 49% in sheep at the age of 6 months - 2 years and significant differences for the rest of the ages. Head and neck lesions recorded the highest infection rate of 28.7 and 34.3% respectively. The study also included the effect of the crude watery extract of Onobrychis ptolemaica
on the parasite, concentrations of 2.5-10 mg/ml have significantly affected parasites, it was noted the greater the concentration, the greater the effect during the different treatment periods. The highest concentration of 10 mg /ml resulted in the disappearance of all scabies parasites on day 14 of the treatment. Results showed sheep infection in Anbar province with mange in both sexes, high incidence of infection in young ages, high rate of infection in the winter months, and head lesions recorded the highest percentage of infection, the results showed the effect of concentrations of the crude watery extract of Onobrychis ptolemaica
plant largely on the parasite.
is an intracellular bacterium can infect both human and animal. Its species especially Shigella dysenteriae
cause shigellosis worldwide, with 165 million cases of severe bloody diarrhea and mucoid feces. The aim of this study was to find a rapid, sensitive and specific method for screening Shigella
in raw bovine contaminated milk. For this goal, 70 samples of milk collected in sterile containers for isolating of Shigella
and culturing it on selective media to identify and characterize its morphology, biochemical and molecular characteristics. This study was compared between three different DNA extraction techniques for polymerase chain reaction (direct DNA extraction using a kit, alkaline DNA extraction, and filtrated milk). Our results showed that PCR was able to detect Shigella
in 15 out of 15 cases after the milk samples filtered. In other words, the filter technique can be used to detect Shigella
in contaminated milk.
This study was conducted for comparison between two different modern methods for the diagnosis of the nematode worms' infection in sheep we used acridine orange fluorochrome and specific staining kit in fecal samples. We examined 50 sheep fecal samples; the total infection rate was about 96% when was used lectin - fluorescein kit while the total infection rate was 74% when we used acridine orange fluorochrome technique. In conclusion of this study indicated that lectin - fluorescein kit is more effective than acridine orange fluorochrome in the diagnosis of nematode worms' eggs. Also, we conclude from this study the importance of using fluorescence - lectin kit technique in the diagnosis of nematodes eggs because they are distinguished by their speed, efficiency and accuracy, as they compare with the fecal culture technique to cultivate the larvae from eggs in order to diagnosed the type of nematodes eggs, the lectin - fluorescein kit technique is the first in Iraq.
