Control of bovine virus diarrhoea virus.

Prevalence of Bovine Viral Diarrhoea Virus antibodies and antigen among the aborted cows in industrial dairy cattle herds in Mashhad area of Iran

The measurement of antibody responses of animals exposed to BVDV either through a natural exposure or an immunization protocol is still a standard procedure. For BVDV, the test formats have been largely limited to ELISA which is a valuable diagnostic test to measure the level of BVDV specific antibodies as well as antigen in blood samples. In the present study, 120 blood samples were collected ...

Detection of Bovine Viral Diarrhea Virus Using a Nested RT-PCR Assay in Bulk Milk Samples of Dairy Cattle Herds in Suburb of Mashhad-Iran

Bovine viral diarrhoea virus (BVDV) is an important pathogen of dairy cattle. In this study, bulk milk samples representing a total of 4105 milking cows, from 18 dairy cattle herds in the suburb of Mashhad- Iran, were tested for presence of BVDV by the use of a nested reverse transcription polymerase chain reaction (Nested RT- PCR) assay.

Serological study of bovine viral respiratory diseases in dairy herds in Kerman province, Iran

Respiratory disorders are major concern for dairy cattle industry. Viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. The most important viral agents arebovine viral diarrhoea virus (BVDV), bovine herpes virus type 1 (BHV-1), bovine respiratory syncytial virus(BRSV), parainfluenza virus type 3 (PIV-3) and bovine adenovirus (BAV). This cros...

بررسی سرولوژیکی آلودگی به اسهال ویروسی گاو در گاوهای اهواز
