BACKGROUND: Infectious Bovine Rhinotrachitis (IBR) caus-ed by Bovine Herpes Virus-1 (BoHV-1) was first, observed in one of the Tehran Industrial cattle breeders, with importation of cattle in 1965. Later, the isolation of bovine herpes virus approved the existence of the disease in the most of the provinces of the Iran. OBJECTIVES: Presence of antibodies against BoHV-1 was evaluated in young bo...
Two vaccine, two respiratory (infectious bovine rhinotracheitis [IBR]), and two genital (infectious pustular vulvovaginitis [IPV]) strains of infectious bovine rhinotracheitis virus were compared by neutralization kinetics using late 19S antibody (AB). The two vaccine strains were indistinguishable from one another, but were neutralized far more rapidly than the other four strains when either a...
Preliminary characterization of viruses isolated from cases of epididymitis and vaginitis in cattle.
Twelve slow-growing virus isolates propagated in tissue culture from cattle with epididymitis and vaginitis were identified as herpes viruses by virtue of their biological, physicochemical and morphological characteristics. None of the 12 virus strains proved to be serologically related to the infectious pustular vulvo-vaginitis-infectious bovine rhinotracheitis (IPV-IBR) virus, but a further 3...
Two hundred and thirty-nine cattle from Gauteng Province in South Africa were tested for various pathogens causing reproductive diseases includingbovine viral diarrhoea/mucosal disease (BVD/MD) virus, infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) virus, Neospora caninum and Brucella abortus usingvarious tests. For BVD/MD virus, 49.37% tested positive, 74.47% for...
the objective of this study was to determine the protein pattern and antigenic structure of bhv-1. ten viral isolates from cows with clinical signs of respiratory infections were selected for this study and confirmed by sn test. all samples were cultured on cell cultures and purified by ultracentrifugation. purified isolates were electerophorsed using sds-page method and immunoblotted. vi...
این تحقیق با هدف مطالعه الگوی پروتئینی و بررسی پادگن های دخیل در ایمنی همورال در فاصله زمانی بهار 1382 تا بهار 1384 انجام گرفت. 10 نمونه ویروس ibr جدا شده از موارد تنفسی بیماری، که قبلا با توسل به آزمون خنثی سازی سرم تایید شده بودند.برای این منظور انتخاب گردیدند. کلیه نمونه ها در کشت سلولی تکثیر شده و پس از خالص سازی به روش اولترا سانتریفوژ، آزمون sds-page و ایمونوبلاتینگ با سرم های مثبت مربوط ...
