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 کاملGlycoproteins of bovine viral diarrhoea-mucosal disease virus in infected bovine cells.
Bovine cell cultures infected with bovine viral diarrhoea-mucosal disease (BVD) virus were radiolabelled with L-[35S]methionine or D-[2-3H]mannose followed by analysis of the labelled polypeptides by radioimmunoprecipitation and polyacrylamide gel electrophoresis in one and two dimensions. Six glycoproteins were detected in infected cells. Two abundant species had Mr of 48K and 56K to 58K while...
متن کاملHomologous interference by an actively multiplying noncytopathic strain of bovine virus diarrhea-mucosal virus.
Reduction in plaque size of cytopathic strains of bovine virus diarrhea-mucosal disease virus was determined to be a more sensitive indicator than number for detecting the interference induced by the noncytopathic strain of virus in cell cultures.
متن کاملThe 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 کاملHaptoglobin and Serum Amyloid A Responses in Cattle Persistently Infected with Bovine Viral Diarrhea Virus
Background: The acute-phase response to infection is also characterized by an increase in protein turnover plus an increased loss of protein. Leukocyte proliferation and the synthesis of cytokines, immunoglobulins and positive acute phase proteins(APPs) contribute to protein turnover APPs levels, as markers of inflammation, usually rise significantly during the course of acute and chronic infec...
