  • strains
  • This study describes the isolation of BVD viruses, gene sequence analysis of the 5' non-translated region (5' NTR) of the genome, the generation of phylogenetic data of local strains and the recording of clinical signs associated with each isolate. (up.ac.za)
  • Molecular
  • Defining the molecular stress pathways leading to cpBVDV-induced apoptosis provides the basis to study how other ER-tropic viruses, such as hepatitis C and B viruses, modulate the host cell ER stress response during the course of persistent infection. (asm.org)
  • dairy
  • In this study, the cellular localisation and distribution of BVD viral antigens in genital system tissues were investigated in 65 non-pregnant dairy cows and in 65 bulls. (duhnnae.com)
  • BVD viral antigens were determined in 15 of the 65 non-pregnant dairy cows consistent with cell culture results using the indirect immunoperoxidase method. (duhnnae.com)
  • reproductive
  • The difference was statistically significant and indicated a tight connection between infections with IBR and BVD viruses on one hand and occurrence of reproductive disorders or parasitic infections on the other hand. (scialert.net)
  • Neosporosis
  • Bovine viral-diarrhoea (BVD), enzootic bovine leukosis (EBL), Johne's disease (JD), and neosporosis lower on-farm productivity, reduce export competitiveness, and increase consumer concerns regarding safety. (islandscholar.ca)
  • Overall, 37.8, 20.4, 3.4, and 19.2% of all sampled cattle were truly exposed to the Show more Bovine viral-diarrhoea (BVD), enzootic bovine leukosis (EBL), Johne's disease (JD), and neosporosis lower on-farm productivity, reduce export competitiveness, and increase consumer concerns regarding safety.

  • indirect
  • Cp BVD virus-infected cells undergo apoptosis and may promote apoptosis in uninfected cells by an indirect mechanism. (semanticscholar.org)
  • However, whether direct induction of apoptosis in infected cells or indirect effects induced by the virus are responsible for the lesions observed remains to be established. (uzh.ch)
  • clinical
  • The BVD virus causes an acute enteric disease with a variety of clinical manifestations, and is closely related to sheep border disease virus (BDV) and hog cholera virus (HCV). (google.ca)
  • Replication
  • Viruses that use the ER as an integral part of their replication strategy must contend with the ER stress response and the downstream consequences of ER stress signaling. (asm.org)
