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 ...

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...

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. Non of the cows in the herds had been vaccinated against...

A better understanding of the epidemiology and pathogenesis of bovine virus diarrhoea virus (BVDV) has emerged in recent years. Fetal infections and in particular those resulting in birth of persistently infected calves are of central importance for the epidemiology of BVDV. A prevalence of persistently infected, viraemic animals of about 1% is found in Denmark and elsewhere by examination of r...
