This study was carried out on 100 Kidney Samples collected from clinically healthy cattle slaughtered at Mosul abattoir to investigate the renal lesions and to isolate the bacterial causes of these lesions. The bacterial isolation included E. Coli 32%, Corynebacterium spp 27%, Proteus spp 16%, Staphylococus spp 12%, Streptococsus spp 7% while 6% of samples showing no bacterial isolation. The most common gross lesions were seen included multifocal white spots, swallen pale kidneys, congested enlarged kidneys, hyperemic hemorrhagic kidneys. The common observation in histopathological examination reveled to multifocal infiltration of inflammatory cells (Monocytes, Macrophages and Lymphocytes), degeneration and necrosis of epithelial cells lining renal tubules with infiltration of inflammatory cells in the interstitial tissues with atrophy of glomerular tufft. Additionally cysts were observed in kidney tissues.

In present study, we aimed to investigate the pathological changes induced by subchronic oral toxicity induced by sub lethal dose of Di (2-ethyl hexyl) phthalate (DEHP) in Japanese common quail. Forty male quails at one day old were divided randomly into two equal groups, the first group (treated group) was orally administrated by 10% of LD50 of DEHP (557.41 mg/kg of body weight) for 42 days, while second group (control group) left without treatment throughout experiment period. The results of current study showed that there is congestion of kidney, microscopically they showed presence of hyaline degeneration in renal tubules, glomerulosclerosis, wide spread of degenerative and necrotic lesions in renal tubules, hemorrhage, infiltration of inflammatory cell especially macrophages and lymphocytes in interstitial tissue of kidney. While grossing of liver showed hepatomegaly with hemorrhage, microscopically the sections showed wide distributing of vacuolar degeneration (fatty change) in different size and shape of vacuoles in cytoplasm of affected hepatocytes, infiltration of inflammatory cells mainly macrophages and lymphocytes. In conclusion, the oral administration of DEHP at dose 557.41 mg/kg of body weight for 42 days induced degenerative and necrotic irreversible changes in both kidney and liver of Japanese quail that affect their health and production.

Acute Anaplasma ovis infections can cause severe clinical symptoms and might lead to significant economic losses in small ruminant flocks. However, little information has been provided related the prevalence of anaplasmosis in Angora goats. The study was designed to investigate the prevalence of Anaplasma ovis serologically (cELISA) and microscopically (Giemsa stained blood smears) among Angora goats from Duhok districts of the northern part of Iraq. A total of 92 blood samples were randomly collected from three localities of Duhok city; Zakho, Batel and Sumil during the study period from April to October 2009. The infection rate of A. ovis was 38.04% by Giemsa stained blood smear and 66.3% by cELISA. The prevalence of A. ovis in female goats was higher than that in males, but statistically not significant difference (P>0.05) by using both methods. The prevalence was also significantly higher (P<0.05) in goats more than three years old than in younger ones. The highest prevalence of A. ovis was found in Zakho, whereas the lowest was reported in Sumail. Results of hematological parameters indicated microcytic hypochromic type of anemia.It is concluded that A. ovis can infected Angora goats in district Duhok, Kurdistan region, Iraq and this might be due to high distribution of the disease and its transmitters which were lead to substantial effect followed by high mortalities

This study involved the detection of vermicules of Babesia spp in the hemolymph of Boophilus microplus adult females naturally fed on cattle after their remaining a live for 5 to 8 days under laboratory conditions and the detection of some developmental stages (schizonts, rupture of schizonts, small dark collar bodies and migration of vermicules from the hemolymph to different tissues of tick). Both vermicules of B. bovis and B. bigemina were diagnosed. The vermivules of B. bovis appeared as croissant or club-shaped bodies with a broad anterior ending and pointed posterior one and having a central nucleus and a vacuole in the anterior end with a curved or semi curved tail. The vermicules of B. bigemina had a croissant or club –shaped bodies with a lesser width in their anterior end than in B. bovis with no vacuole and with a straight tail. The average length of B. bovis was 13.92 ±1.34 µ with a range of 11.8-15.8µ and average width of 3.23±0.44 µ with a range of 2.7-4µ. The average length of B. bigemina was 11.39±1.12µ with a range of 9.5-13µ and average width of 2.2±0.51µ with a range of 1.5-3µ. The results of current study revealed that their was a direct and proportional relationship between the parasitemia of B. bovis and B. bigemina in cattle blood smears and the number of vermicules in the hemolymph of female of Boophilus microplus. No significant differences were noticed between (number and percentage of Boophilus microplus females) infected with vermicules of Babesia spp at different aged cattle.

Ticks infestation is the major problem of cattle and buffalo of Pakistan. Tick acts as vectors of many viral, protozoal and bacterial diseases and Crimean-Congo Haemorrhagic Fever (CCHF) is one of the most lethal in that list. During the last sixteen years, many sporadic outbreaks of CCHF in Pakistan has been reported with 24 percent case fatalities. In Punjab and Sind provinces mass tick control campaigns have been started to control the tick’s population and spread of zoonotic diseases through tick’s. In these tick control campaigns deltamethrin and ivermectin are used extensively. We highlighted that how extensive use of deltamethrin and ivermectin can adversely affect the environment and possible alternative methods for tick control. Extensive use of deltamethrin can damage the kidneys of insect eating birds and disturb the life cycle of many aquatic organisms if deltamethrin solution is mixed with water of streams. Widespread ivermectin use in domestic animals poses some serious threats to dung beetles and other coprophagic insects as almost 60-80 percent of total dose comes in feces without any metabolism in the body of animal. Decrease in dung beetles can result in decreased dung degradation.

This investigation of Q-fever or Coxiellosis was undertaken to study the presence and the infection rate of C.burnetii infection in reproductively active rams in the Northern Palestine, where most of the sheep herds are located. In all, 2806 samples which collected from active rams during the reproductive season from herds in five cities (Jenin, Jericho, Nablus, Tulkarm and Tubas). Sera were tested by ID Screen® Q Fever Indirect Multi-species enzyme-linked immunosorbent assay (ELISA) for detection of C. burnetii immunoglobulin G (IgG). A total of 28.1 % of ram sera were positive for C. burnetii IgG. There was no significant difference between the four location cities studied However, a significantly low difference was observed in the Tubas city (P<0.05). Highest infection rate was detected in rams of Tulkarm (29.8%), followed by Nablus (29.5%), Jericho (28.4%), Jenin (28.2%) and Tubas (16.1%). Moreover, at the farm level, 73.3% had at least one seropositive animal. It had been concluded that a high infection rate were detected in rams of Northern Palestine, at both individual and herd level. Therefore, Q fever could be responsible for considerable numbers of ovine abortions in Palestine, as well as of public health significance, Hereby control programs should be advised.

C. psittaci is one of the dog’s pathogen which can cause respiratory disorders in various hosts and human beings. Chlamydiae are obligatory interacellular bacteria which belong to Chlamydiales. Conjunctival and pharyngeal swabs were taken from 50 captive dogs presented at veterinary clinics of Isfahan and Shahrekord to determine the percentage of infection and prevalence of C. Psittaci in domestic dogs. Samples were collected during 2014 from a total of 7 different breeds of dog; 1-German shepherd 2-Terrier 3- Mixed Poodle 4-Doberman pinscher 5-Persian sheepdog 6- Siberian husky 7-Pekingese breeds were sampled. The molecular PCR method was used to detect this microorganism in captive dogs and C. psittaci was detected in 9 (18%) of them.

It is well known that Iraq has dry hot weather, especially during summer, so horses sports competitions are stopped. The aims of our research were to study the effect of endurance exercise on sweat constituents of Iraqi Arabian horses. The results show that, after trot, the body temperature was 37.600±0.058, the heart rate was 45.875±0.819, and the respiration rate was 35.750±0.708. After canter, the body temperature was 38.512±0.058, the heart rate was 76.000±0.819 and the respiration rate was 49.250±0.708. After gallop, the body temperature was 39.512±0.058, the heart rate was 99.875±0.819, and the respiration rate was 60.875±0.708. All mean values were significantly different at P≤0.01. The mean of body weight was 460.5 kg. The total body surface mean was 396.1Cm2. The mean values of albumin, globulin, Na+, K+, Cl-, Ca++, Mg++, Fe++, Cu++, and Zn+, in trot were 3.512±0.089, 3.875±0.725, 3.637±0.072, 2.062±0.086, 5.962±0.141, 0.167±0.006, 0.987±0.007, 4.875±0.700, 0.712±0.515, 11.750±0.422 and 0.180±0.002, respectively, while the results in canter were 3.925±0.086, 4.750±0.111, 4.787±0.104, 3.637±0.285, 6.637±0.090, 1.487±0.953, 0.161±0.008, 5.537±0.105, 0.987±0.666, 12.262±0.106 and 0.236±0.007, respectively. In gallop were 5.612±0.107, 6.012±0.158, 6.675±0.144, 5.062±0.138, 7.550±0.090, 2.750±0.122, 0.256±0.009, 6.400±0.070, 1.600±0.845, 12.650±0.073 and 0.276±0.004, respectively. Our results indicate clearly a high loss of essential proteins and minerals during sweating which must be compensated by food additives specially during summer, to prevent many healthy problems so we believe that ratios of these proteins and minerals must be calculated according to many factors like, weather climate, the type of the horse jobs (jump, polo, races, show,…..etc.) and the body weights and ages.

In the present study, forty donkeys of different ages and sexes at Giza Zoo, Egypt were investigated between October 2015 and September 2016 for the presence of hydatidosis disease. Hydatid cysts were detected in the livers of 10% of the examined donkeys and these cysts had a fertility rate 100%. Female donkeys were infected with cysts more than males and all infected donkeys were old aged with no cases of infection were detected in young or adult donkeys. Using molecular tools, the DNA extracted from cysts that had been isolated was subjected to PCR amplification, using synthesized oligonucleotide primers, and these were constructed to target the 299 bp within the (ND2) gene, which is considered to be specific for the Echinococcus equinus genotype. The sequenced PCR products showed homology to E.equinus (G4 or horse strain genotype). These results can be used in future to pursue the epidemiological status of the causative strain of hydatidosis in equines at the study area.

The current study aimed to investigate the effect of garlic juice supplementation with broiler drinking water on performance, immune response, lipid profile, blood picture and activity of liver enzymes under heat stress. For this purpose 100 four days aged broiler checks (Ross) were allocated into control (C) and three treatment groups (25 each). All group checks were housed at 5 ºC above normal ambient temperature during the experiment. Treatment groups (T1, T2 and T3) checks were supplemented with 0.5, 1 and 1.5 ml/L, respectively, with garlic juice in drinking water (6 hrs a day). Food and water were supplemented ad libitum. Body weights were monitored every five days and blood samples were obtained at 25 days for assessment of blood picture and antibody titers after vaccination, total cholesterol and triglycerides concentrations and activity levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were estimated. At 30 days age, T3 group broiler checks reported higher body weights than other groups. Total number of white and red blood cells, hemoglobin concentration, hematocrit levels and ratio of heterocytes to lymphocytes increased significantly in treated groups, whereas significant decline of cholesterol and triglycerides concentrations as well as ALT and AST levels were shown in T3 group broiler checks. Significant increase was shown in the levels of antibody titers against both Newcastle (ND) and infectious bursal disease (IBD) vaccines. In conclusion, treatment of broiler checks early with garlic juice increase broiler performance and immune response against vaccination program and may be protect the broilers from heat stress.

The present study was carried out to evaluate the pathological effects of aspergillosis caused by Aspergillus Spp. in commercial broiler chickens. In this study, we discussed few outbreaks of Aspergillus infection of chicks a week aftter hatching in broiler farms of Duhok-Kurdistan region of Iraq during the period from February to May 2015 on the basis of clinical signs, post-mortem, histopathological and cultural findings. The main clinical signs of the disease in the infected flock included a 3-day onset of labored breathing and neurologic disorders displayed by incoordination, torticollis, and paralysis. Other clinical features included depression, ruffled feathers and gasping. Gross lesions were represented by cheesy granular materials in the air sacs, lungs, and trachea. Histopathology revealed fungal hyphae in sectioned lung tissue. Aspergillus was isolated by culturing in Sabouraud’s dextrose agar from the lesions. The present study deals with the incidence of acute aspergillosis in broiler chicks from Duhok, Kurdistan-Iraq.

The aim of the present study was to evaluate treatment of 20 dogs with femur fractures. Twenty (20) dogs with different ages, breeds, and gender admitted to the clinic of Department of Surgery, Anesthesiology and Radiology-Faculty of Veterinary Medicine-Zagazig University from January 2013 to December 2015 with a complaint of hind limb lameness and were diagnosed as femur fractures through clinical and radiographic examination. German shepherd dogs (85%) and immature dogs (70%) were more susceptible to femur fractures. The most common site of the fracture was the femoral diaphysis (65%) followed by metaphysis (20%). Open reduction and internal fixation techniques were applied using intramedullary (IM) pins with or without cerclage wire (40%) and bone plate (15%) for treatment of diaphyseal fractures, and two cross pins (30%) for treatment of metaphyseal and distal physeal fractures. Pin migration after complete healing (1 case) and bone re-fracture due to jumping (1 case) was the postoperative complications. It was concluded that open reduction and internal fixation methods are the proper treatment for femur fractures if the proper surgical techniques were applied.

The current study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin-α subunit and steroid-free bovine follicular fluid, respectively, on reproductive hormones profile out of breeding season in Iraqi Awassi ewes. Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, used for immunization of male rabbits, and obtaining of SFBFF antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each). At day 38 of experiment, ewes were treated with intra-vaginal sponge impregated with medroxyprogesterone acetate 60 mg for 12 days. Ewes were treated at 0, 28 and 50 days with 4, 2 and 2 ml of normal saline (control; C-ve), 400, 200 and 200 µg of ovalbumine (C+ve), 400, 200 and 200 µg of inhibin (SI group), and 4 ml of normal saline at 0 day, and 4ml and 2ml of SFBFF antiserum, at 28 and 50 days, respectively (AI group). Blood samples were collected at 24 and 48 hours before and after sponge withdrawal for assessment of FSH, LH, inhibin-B, Activin-A, E2 and P4. Before sponge withdrawal, FSH level increased in SI ewes, whereas only after sponge withdrawal, FSH, LH, activin-A and E2 levels increased in SI and AI ewes. Opposite results were shown of inhibin-B level. In conclusion, active or passive immunization against inhibin in Awassi ewes could augment reproductive functions out of breeding season in Iraqi Awassi ewes.
