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.

Livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) has become a global public health concern. The purpose of this study was to investigate the prevalence rates of MRSA infection amongst broiler chickens and broilers farm workers. The total samples used in this study were 306. Cloacal swab samples from 231 broilers and nasal swab samples from 75 broilers farm workers were collected from five farms in Duhok city, Iraq. Isolation and identification of MRSA isolates were carried out and the antibiotic susceptibility were screened. Molecular characterization of all isolates was performed by using polymerase chain reaction (PCR) technique to detect the mecA gene.S. aureus was detected among 84% (63/75) of the farms workers samples and among 84.8% (196/231) of the broiler's samples. The S. aureus isolated from farm workers and broilers appeared resistant to oxacillin 28.6% (18/63), and 32.1% (63/196), respectively. MRSA colonization in farm workers and broilers was 24% (18/75) and 27.3% (63/231) respectively. The S. aureus isolates showed the most resistant to chloramphenicol and the least resistant to vancomycin. The results of the PCR assays revealed that 85.7% (12/14) of S. aureus isolates from farm workers and 44.4% (16/36) of S. aureus isolates from broilers were positive for the mecA gene. The direct handling of broilers by farm workers plays the important role for transport the MRSA isolates from broilers to broilers farm workers.

Troponin-I, homocysteine, Creatine kinase-myocardial band, lactate dehydrogenase and acute phase response had been evaluated in calves with myocarditis due to FMD. The study was conducted on 52 local breed calves 1-6 months old and from both sexes, their dams have no history for vaccination against FMD and show classical foot and mouth disease signs. Ten clinically healthy calves of the same ages were considered as controls. Suspected calves neither show oral blisters, rope salivation, nor foot lesions. Diseased calves showed signs of dullness, in activity, panting with mouth breathing, unable to suck, recumbency, However, five of diseased calves were died within 24-72 hours and on macroscopic examinations of autopsied animals, necrotic myocarditis with pale foci with a zone of hyperemia which were present on the papillary and ventricular cardiac muscles, moreover, on histopathological examinations there were severe inflammatory cells infiltration in the interstitial of myocardial fibers with obvious area of coagulation of myocardial fibers and marked area of hyalinization, furthermore, severe mononuclear cells infiltration, mainly lymphocytes, with few neutrophils closed to necrotic myocardial fibers were also detected. Diagnosis of FMD virus was confirmed by using commercially NSP ELISA kits for foot and mouth. A significant increase (p>0.05)was encounteredin body temperature, respiratory and heart rates in diseased animals than in controls, Furthermore, abnormal cardiac sounds (organic murmurs) were indicated on auscultation of the heart. Results of hematological parameters shown a significant increase indicated in ESR values of diseased calves than in controls, moreover, total leukocyte count was increased significantly with significant lymphocytosis. Furthermore, the results were also showed significant increase in values of serum cardiac troponin, homocysteine, creatine kinase-myocardial band, lactate dehydrogenase, haptoglobin and fibrinogen in seropositive calves for FMD compared with controls. It can be concluded that determination of cardiac biomarkers and acute phase response concentration in calves with myocarditis can considered as a guide to quantify early heart damage.

This study was carried out in Sulaymaniyah province, Iraq to estimate the concentration of some biochemical parameters and trace elements in the serum of sheep infected with the metacestodes of Taenia hydatigena. The present study included the measurement of some biochemical parameters as total protein, albumin and globulin and evaluation of trace elements as zinc, copper and iron using automatic analyzer and spectrophotometer respectively. For this purpose, up to 40 serum samples from sheep infected with T. hydatigena cysts and 10 serum samples from non-infected group had been used. The findings of the current study showed significant elevated levels in both total protein and globulin compared to non-infected group, where the total protein and globulin levels were 8.04 ± 0.275 g/dl and 5.90 ± 0.321 g/dl respectively, compared to the non-infected group 6.686 ± 0.409 g/dl and 4.124 ± 0.479 g/dl respectively. While, the mean serum albumin in infected sheep was significantly decreased 2.14 ± 0.224 g/dl compared to non-infected one 2.562 ± 0.152 g/dl. About the results of trace elements, the serum Cu was significantly increased in infected group 1.42 ± 0.466 mg/L compared to non-infected one 0.90 ± 0.171 mg/L, while the mean serum Zn concentration was significantly decreased in infected group 0.37 ± 0.230 mg/L compared to non-infected group 0.70 ± 0.108 mg/L. Although, the mean serum Fe of infected sheep 1.42 ± 0.388 mg/L was slightly lower than non-infected one 1.26 ± 0.490 mg/L, statistically there was no significant difference between them. It was concluded that T. hydatigena cysts had significant effects on serum total protein, globulin, Zn and Cu.

Shigella 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.
