    This experiment was conducted to determine effect of different extender on recovery and storage of epididymal ram spermatozoa. Testes were obtained from eight mature rams which were slaughtered at four different occasions, a pair in each session. Caudal epididymis was isolated and divided to four equal parts. Spermatozoa recovery from each part of the caudal epididymis was performed by milk (M), Tris (T), Tris plus caproic acid (T-C) and sodium citrate (S) extenders. Spermatozoa in each extender were divided into four parts and then the amount of 0 (E0), 5 (E5), 10 (E10) and 15% (E15) egg yolk were added. Samples were chilled to 4 °C and stored for 7 days. The evaluation of sperm motility, viability, membrane integrity and acrosome integrity were performed daily. The results showed that there was interaction between egg yolk and storage time and also egg yolk and extender on sperm motility (p

    The aim of the present study is to investigate the effects of a sustained-release simvastatin in collagen-polyglycolic acid scaffold on bone formation in the rabbit calvarial critical-sized defect. This study was carried out to examine if maximum bone regeneration with less inflammation would be attained by combining an optimal dose of simvastatin with Collagen-Polyglycolic acid scaffold, which is an osteoconductive biomaterial capable of releasing the drug slowly. To induce critical-sized calvarial defect in the 10 nominated adult New-Zealand rabbits we trephined four holes measured 5-mm-diameter into each head, and filled them with preparations of different doses of simvastatin (0.5 mg, and 1 mg) blended with Collagen-Polyglycolic acid, Scaffold alone or left empty. Five animals were sacrificed after 4 weeks and the rest of them after 8 weeks and examined histologically. Statistical analysis revealed that in the first time frame (the first four weeks), the difference between the control group and the simvastatin 0.5 mg group on one hand and the simvastatin 1 mg group and the control group on the other hand, there were statistically significant difference between (p

    A homing pigeon (Columba livia domestica) was referred with the presence of ulceration, bleeding, loss of feathers and scabs and crust in the head. Mycological evaluation was shown simultaneous infections by Malassezia and Microsporum gallinae. Pathological findings revealed severe and deep necrotic skin lesions associated with fungal hyphae and especially numerous yeasts. It was concluded that keratinophilic fungi, especially dermatophytes in skin and feathers of birds can cause severe lesions and be a potential source of spread of disease in the human population and animals. It also suggests considering the role of Malassezia spp. as a risk factor in the development of skin lesions and the emergence and exacerbation of infections such as dermatophytes.

    The overuse of antibiotics in poultry industries may lead to a rise in antibiotic-resistance, in humans and animals. Natural antibiotics degrade in living tissues, and therefore, they do not induce antibiotic-resistance. In this study, the antibacterial activity of six organic solvent extracts of S. iranica were investigated against S. typhimurium. The results indicate a significant antibacterial activity of S. iranica extracts against S.typhimurium (p

    Clostridium perfringens has been known as a cause of diarrhoea in dogs. The aim of this research was isolation C. perfringens by culturing and toxinotyping by PCR molecular method. In this research 151 dogs’ faecal samples were collected from northwest of Iran, 131 of which were apparently healthy, and 20 of which were diarrheic. These faecal samples were cultured on 5% sheep blood agar; the suspected colonies with double homolysis that using multiplex and single polymerase chain reaction (PCR) assay were admitted to detect toxinotypes of the isolates by specific primers. C. perfringens strains were isolated from 5/20 (25%) the diarrheic group and 31/131(23.8%) the non-diarrheic group. All isolates (36/151) were classified as C. perfringens type A (cpa). Fourteen isolates (38.8%) with cpa犖瞭tpeL- profile and one isolate (2.8%) had cpa犗뺝tpeL- toxin’s profile. More studies are needed to elucidate the epidemiology of C. perfringens in dogs and its role as a zoonotic agent and public health hazard. Based on author’s knowledge, this is the first study was performed in order to isolation C. perfringens and genotyping from dogs in Iran. The cpa犗 gene was reported from one C. perfringens isolated from healthy dogs.

    Canine compulsive disorder such as tail-chasing is a syndrome of abnormal behaviors that affects many breeds. This disorder may be associated with serum lipid elevations in dogs, so the objective of the present survey was to characterize serum lipid profile changes in dogs with tail chasing behavior disorder. Twenty seven companion dogs with tail chasing were selected among the referred cases to the Veterinary Hospital of Shahid Chamran University of Ahvaz. The affected dogs were diagnosed on the basis of the dog’s behavioral history (age, frequency and duration of bouts since onset, intensity of the behavior, current or previous medical assessments) and clinical signs. Serum total cholesterol, triglycerides, HDL-C, LDL-C and VLDL-C levels were measured using commercial kits. Twenty seven control dogs were also enrolled on the basis of normal physical examination results, complete blood count and serum biochemistry profiles. Dogs with tail chasing disorder had significantly higher total cholesterol (p 0.05). When all parameters were compared, there was no significant difference between the affected dogs younger and older than one year (p > 0.05). In conclusion, tail chasing disorder may be associated with marked elevations of serum cholesterol, HDL-C and LDL-C levels in dogs. These indices may be used as biochemical parameters of tail chasing disorder in clinical settings.

    The pine marten (Martes martes) is a medium sized carnivore rarely found in Iran. The aim of this study was to describe species-specific characteristics of the celiac artery in pine marten. In pine marten examined in this study, it was observed that the celiac artery originated from the ventral aspect of abdominal aorta. The celiac artery was divided into two branches. A thick branch was the common trunk of the splenic and the left gastric arteries, namely the gastrosplenic trunk and the other branch which was thin and longer, namely the hepatic artery. The splenic artery was divided into three branches that supplied the spleen. In the examined pine marten, there were two left gastroepiploic arteries, one originated from the splenic, and the other from the left gastric artery. The hepatic artery was extended to the portal fissure of liver and had five following branches: pancreatic branch, gastroduodenal, right gastric, left hepatic, and right hepatic arteries. The right gastroepiploic artery was originated from the gastroduodenal artery. This is the first report on ramification of the celiac artery in the pine marten

    Leptospirosis is a zoonotic infectious disease of worldwide distribution. The infection is caused by various serovars of Leptospira interrogans sensu lato. Although the squirrels and hamsters are considered to be the reservoir or maintenance host of Leptospira, but little is known about the status of leptospirosis in these animals. This survey was conducted to evaluate the seroprevalence of Leptospiral infection in squirrels and hamsters in Ahvaz district, SouthWest of Iran. Blood samples were taken from 35 squirrels and 35 hamsters. Sera were screened for antibodies against serovars of L. canicola, L. icterohaemorrhagiae, L. grippotyphosa, L. ballum, L. hardjo, L. pomona, L. australis and L. tarassovi using the microscopic agglutination test (MAT). From a total of 35 squirrels, three cases (8.57%) were serologically positive for the serovars of L. grippotyphosa (2.86%), L. pomona (2.86%) and complex of L. hardjo L.
    canicola L. grippotyphosa L. pomona (2.86%). Positive results were detectable at serum dilutions of 1:100 to 1:400. Seroprevalence did not show a significant difference for age and sex in the studied squirrel (p > 0.05). From a total of 35 hamsters, six cases (17.14%) were serologically positive. The predominant titers were directed against serovars of L. grippotyphosa (5.71%), L. grippotyphosa L. pomona (2.86%), L. pomona (2.86%), L. icterohaemorrhagiae (2.86%) and L. canicola (2.86%). The positive results had 1:100 serum dilutions. Prevalence was significantly higher in adult hamsters above one year compared to hamsters less than one year (p 0.05). This survey indicated that serovars of L. grippotyphosa and L. pomona were predominant. The results provide useful information on the seroprevalence of leptospirosis in squirrels and hamsters of Ahvaz district.
