The prevalence of bovine viral diarrhea virus in persistently infected cows in industrial dairy herds in suburb of Mashhad- Iran
Bovine Viral Diarrhea Virus (BVDV) is a Pestivirus of the Flaviviviridaefamily that infects cattle, and its widespread distribution can cause substantial economic losses worldwide. The aims of this study were: (1) to estimate the prevalence of animals persistently infected (PI) with BVDV in industrial dairy cattle herds in suburb of Mashhad- Iran; and (2) to compare the occurrence of persistent...
متن کاملDemonstration of bovine viral diarrhoea virus in peripheral blood mononuclear cells of persistently infected, clinically normal cattle.
Peripheral blood mononuclear cells (PBL) from cattle known to be persistently viraemic with bovine viral diarrhoea virus (BVDV) following a foetal infection, were examined for the presence of viral antigens and cell-associated infectious virus. Using immunocytochemical techniques, physical separations of PBL subsets and virus isolation techniques (directly and by cocultivation) it was found tha...
متن کاملFive hours to identify immunotolerant cattle, persistently infected with bovine virus diarrhoea virus.
Detection of animals which are persistently-infected with bovine virus diarrhoea virus (BVDV) is of prime importance in the control of pestivirus infections in cattle, as these animals constitute the main reservoir of the virus. Identification of such animals can be readily performed using crude whole blood samples with a sandwich enzyme-linked immunosorbent assay (ELISA) requiring only approxi...
متن کاملCohabitation of pregnant white-tailed deer and cattle persistently infected with Bovine viral diarrhea virus results in persistently infected fawns.
Economic losses due to infection with Bovine viral diarrhea virus (BVDV) have prompted introduction of organized control programs. These programs primarily focus on the removal of persistently infected (PI) animals, the main source of BVDV transmission. Recently, persistent BVDV infection was demonstrated experimentally in white-tailed deer, the most abundant wild ruminant in North America. Con...
متن کاملInactivation at various temperatures of bovine viral diarrhea virus in beef derived from persistently infected cattle.
Bovine viral diarrhea virus (BVDV) is a pestivirus that is enzootic in most cattle populations throughout the world. This virus is present throughout the body of persistently infected (PI) cattle. Previous research has not assessed the cooking temperature at which BVDV in meat from PI cattle can be inactivated. Therefore, muscle tissue from 6 PI cattle was harvested, refrigerated, frozen, and h...
