Escherichia coli often lead to foodborne pathogen and generally considered public health importance. Escherichia coli can be produce one or more Shiga toxins, which may produce diarrhea, hemorrhagic colitis and life-threatening hemolytic uremic syndromein humans and animals .The aim of the present work was to investigate the Escherichia coli groups A, B1, B2 and D of 80 samples from beef cattle in sanandaj . result shows that 34 samples(42.5%) E. coli isolated and identified based on standard procedures and PCR method with uidA gene .phylogenetic group of each strain was determined by using multiplex PCR method with chuA ,yjaA and segment of DNA TspE4C2. In this study, Among the strains isolated e.coli from beef cattle were allocated into phylogenetic group A (61.76%), B2 (5.8%), D(26.62%) and group B 1 (8.82%). Detection of E.coli isolation is very important and shows that food of animal origin can be of a reservoir that potentially could be transferred to humans the food chain.

Consistent intake of sand (and soil) with unprotected feed in the feces may cause it to accumulate in the gastrointestinal tract and lead to gastrointestinal disorders, This study is a report of the study of sand accumulation in the gastrointestinal tract of Kurdish horses by diagnostic methods. So far, there have been no reports of horse butter from any breed in Iran. Therefore, none of the available studies includes the evaluation of the prevalence and diagnosis of sand without signs of accumulation in the gastrointestinal tract of foal. This study is also the first study to examine the foal. The aim of this study was to evaluate the level of sand accumulated in the gastrointestinal tract of healthy horses and to compare ultrasound and the amount of sand excreted. Abdominal ultrasound was evaluated. Ultrasound examination showed the presence of sand, sand was found in a single place, usually detected in the left diagnostic window. The mean amount of sand was 0.18 ± 0.21 g per 100 g of feces. Sand may accumulate in the gastrointestinal tract without any clinical signs. The amount of sand excreted in the stool does not indicate the amount of sand accumulated in the gastrointestinal tract. Abdominal ultrasound examination should be combined with it for more specific results.

Developmentally orthopedic diseases include a set of syndromes that cause irregular skeletal growth in the spheres. One of these syndromes is physiitis, which is seen in newborn horses. Physiitis occurs when the process of intra-articular ossification in growing horses becomes unbalanced. The most common ages for the occurrence of physitis in horses are 4 to 8 months or 1 to 2 years. If the disease occurs, it can cause pain, difficulty walking and even deviation in the limb, which will eventually lead to reduced horse performance. Many factors have contributed to physitis, including poor nutrition, genetics, weight gain, hard work and exercise. If timely diagnosis and elimination of the factors affecting the incidence of the disease and appropriate treatment, the progression of the disease can be prevented. Diagnosis by clinical examination and radiography will be very helpful because of the changes in the growth plate and the degree of ossification. The aim of this study was to introduce and study the case of this anomaly in the horse in Gonbad Kavous. An 18-month-old horse was referred to a veterinarian with signs of pain in his arm and lameness, which were diagnosed after examining the clinical signs and vital signs and then taking a radiograph of the physiitis.

The main goal in the repair of tibial fractures is to create a bone unit and study the effect of this nano polymaterial in the process of bone repair. In this research, 10 adult goats were divided into two groups, and the middle part of the right tibia was considered to create a 30 mm defect. . poly(e-caprolactone)/Gelatin/Gehlenite was used to fill the gap after the fracture in the second group. Then, on days 0, 15, 30, and 60, the animals in both the experimental group and the control group are radiographically examined. The results obtained from these results are based on the Lin and Sandow classification system depending on the amount of callus found and the spatial amount of the defect filled by the callus, mineralized and compared, after analysis And statistical analysis shows. There was a statistically significant difference between the two groups (P < 0.05); This confirms the faster bone formation in the experimental group than the control group and more form of poly(e-caprolactone/Gelatin/Gehlenite) in tibial bone reconstruction.

Common human and animal parasitic diseases encompass a wide range of zoonotic diseases, the most important of which are liver hydatid cysts and trematodes, which are of great economic and economic importance. This study was conducted through slaughterhouse and slaughter inspection as well as post-slaughter visit data over four seasons on 58642 slaughtered animals including 15340 sheep, 6239 cattle and 37063 goats. In this study the incidence of Fasciola infection in cattle 3.1%, sheep 1.5%, goat 0.9%, prevalence of liver hydatid cyst infection in 1.2%, sheep 2%, goat 1.1% and prevalence of hydatid cyst infection in cow 3.5 %, Sheep 4.9% and goat 2.7%. This study shows that the prevalence of the above parasites is relatively high, which in addition to imposing economic losses due to livestock losses and the capture of infected carcasses or limbs, as well as reducing livestock production, indicate the existence of health hazards for the inhabitants of the area. Due to the life cycle and transmission of these parasites, they require more comprehensive and comprehensive health and control measures.

Dourine is a parasitic venereal disease of horses caused by the flagellated protozoan Trypanosome equi perdum from the Trypanosomatida's order. This deadly disease, which existed in the past and is emerging again in Lorestan today, has not been investigated in Lorestan despite suspected cases.Therefore, for this purpose, venous blood samples (4 stallion samples and 9 mare samples) were collected from 13 suspected horses by referring to four villages on the outskirts of Dorood city, were collected from May 2020 to May 2021. The results of the field examination of the animal include fever of 38.5 ± 1 degrees Celsius, edema of the genital tract and rapid fatigue, and paleness of the eye mucosa, eye hyperemia (6 cases of fever and 2 cases of eye infection), cardiac tachycardia, and in one case of a stallion, a skin plaque with a diameter of 5 Centimeters were seen on the leg. From each horse, 20 ml of blood was taken from the Vedic vein, and the samples were analyzed by the method of preparing a slide from a buffy coat and measuring the hematocrit in a capillary tube. Out of 13 horses studied, 7 cases showed a hematocrit of 32 ± 1%. The average hematocrit was 28% ± 1 in 4 stallions and 30% ± 1 in 3 mares. The trypomastigote forms of the parasite Trypanosome equipurdum, with an average absolute frequency of the disease of 23.07%, were seen in three samples
