Persistent bovine viral diarrhea virus (BVDV) infection in cattle herds
Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...
متن کاملThe first study of bovine immunodeficiency virus (BIV) and bovine viral diarrhea virus (BVDV) co- infection in industrial herds of cattle in two provinces of Iran
BIV is a well-known bovine immunosup-pressive cause, but its pathogenesis has not been well characterized. It seems that it is possible that cofactors such as co- infection with other bovine viral pathogens may play a role in enhancing the pathogenesis of BIV infection; BVDV also has immunosuppressive effects. OBJECTIVE: The aim of this study was determination of possible correlation between BI...
متن کاملFatal congenital anaplasmosis associated with bovine viral diarrhoea virus (BVDV) infection in a crossbred calf.
Clinical disease resulting from the vertical transmission of Anaplasma marginale has only been reported on 5 occasions despite studies demonstrating successful in utero transmission. During the reported experimental induction of congenital anaplasmosis in calves, the outcome was variable but mostly led to inapparent or mild infection. There are previous case reports of fatal congenital anaplasm...
متن کاملDetection 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. Non of the cows in the herds had been vaccinated against...
متن کاملBovine Viral Diarrhoea Virus (bvdv) Infection in Pregnant Cows and Their Foetuses
The aim of the study was to characterize bovine viral diarrhoea virus (BVDV) infection in pregnant cows and their foetuses. Blood samples from 64 clinically healthy cows, determined as pregnant after slaughter, and from their foetuses were collected into tubes with and without EDTA. In total 128 blood samples were examined for BVDV antibodies and 128 leukocyte samples for BVDV antigens by direc...
