The study was conducted at the of animal fields in AL-Qassim city, sheep in this fields was suffering from severe eye infection during the period April to October ,2015 .sheep was clinically examined and showed signs copious eye drops, increase body temperatures, swollen of eye with redness, eye pus in some cases, the sheep was checked clinically and eye swabs of 20 keratoconjuctivitis affected sheep carried out on the basis of their culturing,morphology, staining,biochemical tests and antimicrobial susceptibility testing was done by (disc diffusion method and well diffusion method) from present study .percent of infection was S.aureus(50%), M.ovis (33%)and Proteus spp.(17%) was isolated . Result of antimicrobial properties of Aloe Verawas evaluated in various in-vitro experiments against these species of bacteria S.aureus,M.ovis and Proteus spp. and showed good inhibition activity.In vivo study recovery from the conjunctivitis was record after 6 -10 days for animal treated with Pencillin-Streptomycine while group of extract that showed complete healing during period 6-10 day according totype and severity of infection, also there is no recurrent infection after treated with aloe Vera ointment and eye lotion , as well as Gide to done many of research on aloeVera for used in eye problem which consider very important in Veterinary Medicine .

The toxic influence of dietary copper(Cu) and cobalt (Co) on the accumulation and body weight examined in broiler chicken. This experiment was conducted to investigate the toxic effects of dietary Cu and Co on chicks body weight and organ, content of the tissues of these two metals was also detected. One day age chicks of Gallus gallus domesticus fed diet supplemented with 500, 1000,1500ppm of Cu, second group exposure to 100,500, 1000ppm of Co in feed daily during 4 weeks. The control groups were fed without supplementation of metals. The concentrations of Cu and Co resulted in increased of Cu and Co content in liver, gizzard and muscle. Body weight of chicks was decreased by Cu and Co high concentration treatments. On the other hand, Liver weigh in chicks was significantly (P

The present study was carried out to determine the vascularization of long bone in laboratory animal. Fourty healthy guinea pigs have been used and the result showed that, at 10 days old embryo showed newly differentiated blood cells at the future cartilaginous template. At age of 25-35 days only the osteoprogenitor cells, osteoblasts and osteocytes were seeing. At 43 old embryos the hematopoiesis and vascularization were clearly by formation free blood cells and newly formed blood vessels in the marrow cavity. At 54 old day embryo the hematopoiesis was increased and the differentiation of immature white blood cells was noticed at age of 65 day. At the postnatal periods showed a nutrient artery within marrow cavity.

This study was designed to explore the effect of nitrate ion on induction of diabetesexperimentally in laboratory mice.Fifteen white mice, 7-8 week olds were randomly dividedinto three equal groups. First group was administrated orally o.3 ml of nitrateion(concentration was 0.25gm/10ml D.W) daily for one month. Second group was administratedorally o.3 ml of potassium nitrate (concentration was 0. 5gm/10ml D.W) daily foronemonth. Third group was administrated orally with 0.3 ml of distilled water (D.W) daily forone month.After 30 post administrationthe concentration of blood glucose of infectedanimals treated with nitrate ion increase in both first and second groups when compared withcontrol group.The histopathological change study showed pathological lesions in pancreasof first grouptreated with nitrate ion showed the exocrine region and islets of Langerhans with damageddue to necrosis, while the second group wasinfected with nitrate ion showed the exocrineregion and islets of Langerhans with necrosis and congestion of blood vessel

The aim of this study was to evaluate therapeutic efficacy of atropine in case ofcholinesterase (ChE) inhibitors toxicity in chicks subjected to oxidative stress (OS) withhydrogen peroxide (H2O2). H2O2 at 0.5 % in drinking water induced OS at age of 7-14days in the chicks when given each day for 14 consecutive days. There was no change inthe acute median lethal dose (LD50) for diazinon (7.9 mg/kg, orally) for both H2O(control) and H2O2 groups. The therapeutic efficacy of atropine was decreased (265 %)when measuring the median effective dose (ED50) for treating the diazinon toxicity inH2O group (2.6 mg/kg, i.m.) and in the H2O2 group (9.5 mg/kg, i.m.). The signs of acutediazinon toxicity were found to increase in H2O2 groups when compared to H2O groupand there is slight decrease in plasma and whole brain ChE activities in H2O2 group whenwhen compared to H2O group. The data revealed a decline in atropine efficacy for treatment diazinon toxicity in chicks that suffered from OS status and it is recommendedhere to increase the dose of atropine in this case.

Streptococcus zooepidemicus is one of the the main causitive opportunisticpathogen of the equine genital system and one of the secondary bacterial diseasethat causes mucosal bacterial infections . In the present study, PCR techniquewas used to detect S. zooepidemicus directly from uterine samples of infectedmares based on specific amplification superoxide dismutase (sodA) gene primersthat were designed by using the partial sequence of S.equi subsp. zooepidemicusstrain 65843 superoxide dismutase (sodA) gene, (GenBank: GU436869.1) andprimer3 plus for PCR primer design. The results showed high prevalencedetection of S. zooepidemicus (76%) positive uterine swab samples (38/50). Thisstudy was concluded that S. zooepidemicus is the one of silant pathogen thatcause metritis in mares. PCR is very fast and specific tool used to detect of S.zooepidemicus.

Caseous lymphadenitis caused by Corynebacterium pseudotuberculosis is achronic worldwide disease of sheep and goats resulted in abscess formation insubcutaneous and internal lymph nodes. Indirect immunosorbent assay (ELISA) wereused for detection of anti PLD IgG antibodies of C. pseudotuberculosis in twohundred and five serum samples collected from sheep flocks and from Al-shuallaslaughterhouse in Baghdad. The seropositive percentage was 15.12 of the total seratested. A non-significant of higher positive percentage of CLA was seen in the femalesheep as comparison to male one A higher seropositive percentage was recorded inold age group in comparison to younger one.

Little is known about latent infection and molecular characterisation of Neospora caninum in sheep (Ovis aries). In this study, 330 sheep samples (180 hearts and 150 brains) were analysed for N. caninum DNA by nested polymerase chain reaction (PCR) targeting the Nc-5 gene. Neospora caninum DNA was detected in 3.9% (13/330) of sheep samples. The parasite’s DNA was detected in 6.7% of heart samples (12/180) and 0.7% (1/150) of brain samples. No clinical signs were recorded from infected or uninfected animals. Sequencing of the genomic DNA revealed 96% – 99% similarity with each other and 95.15% – 100% similarity with N. caninum sequences deposited in GenBank. To our knowledge, this is the first report on the use of PCR to identify latent neosporosis in sheep in Iran. The results of this study have the potential to contribute to our understanding of the role of N. caninum-infected sheep in the epidemiology of neosporosis.
