Hepatitis C virus (HCV) is classified in the genus Hepacivirus of the family Flaviviridae, whose members have a single-stranded RNA genome of positive polarity, which encodes a single polyprotein. Within this family, HCV is closely related to viruses of the genus Pestivirus, which includes classical swine fever virus (CSFV). Translation of the hepaci- and pestiviral polyprotein is initiated by ...

BACKGROUND In the context of the ongoing eradication campaign for bovine viral diarrhea virus (BVDV) in cattle in Switzerland, the role of South American camelids (SAC) as a possible virus reservoir needed to be evaluated. OBJECTIVE To assess and characterize the prevalence of pestivirus infections in SAC in Switzerland. ANIMALS Serum samples collected from 348 animals (40 herds) in 2008 an...

BACKGROUND The roe deer is the most abundant and widespread wild Eurasian cervid. Its populations are expanding and increasingly in contact with livestock. This may affect the distribution of infectious diseases shared with other wild and domestic ungulates. METHODS We investigated the antibody seroprevalence against Pestivirus, Herpesvirus, Bluetongue (BT) virus, M. avium paratuberculosis (M...

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...

La diarrea viral bovina (DVB) es una patología infecciosa generada por un pestivirus de distribución mundial, causante problemas reproductivos y pérdidas económicas. El objetivo del presente estudio fue establecer la positividad al virus (vDVB) en vacas municipio Tuta (Boyacá, Colombia), analizar los grupos etarios, raciales las variables reproductivas manejo como posibles factores riesgo. Se t...

Serological survey on the occurrence of alpha-herpesvirus and pestivirus infections in the population of European bison in the Bialowieza Primeval Forest was conducted. Sera from 40 randomly selected individuals were tested using two commercial IDEXX ELISA tests. The study design allowed excluding or confirming the infection with the probability of 95% and at the expected prevalence of 30%. No ...

A post-pubertal bull on an artificial insemination station was found to be persistently shedding bovine viral diarrhoea virus (BVDV) in semen over a period of eleven months, while demonstrating no viraemia. Circulating antibodies to BVDV were consistently high, suggesting that the immune system was challenged repeatedly. Post-mortem findings confirmed that the virus was sequestered in the teste...
