Development of a RT-PCR ELISA for simultaneous detection of BVDV-1, BVDV-2 and BDV in ruminants and its evaluation on clinical samples

Journal of Virological Methods, 2015
The aim of this study was to develop a reverse transcription polymerase chain reaction ELISA (RT-PCR ELISA) for detection of ruminant pestiviruses and to evaluate its diagnostic performance on clinical samples obtained from cattle, sheep and goats.

Effects of oocytes exposure to bovine diarrhea viruses BVDV-1, BVDV-2 and Hobi-like virus on in vitro-produced bovine embryo development and viral infection

Theriogenology, 2017
As production of in vitro (IVP) bovine embryos steadily increases, the sanitary risk associated with IVP embryos remains a concern. One of the greatest concerns is how BVDV may be transmitted through IVP embryos. The objective of this study was to evaluate the effects caused by BVDV-1, BVDV-2 and Hobi-like virus exposure during in vitro maturation on ...

Nucleotide sequence homology to bovine viral diarrhea virus 2 (BVDV 2) in the 5′ untranslated region of BVDVs from cattle with mucosal disease or persistent infection in Japan

Veterinary Microbiology, 1998
Cytopathogenic and non-cytopathogenic bovine viral diarrhea viruses (BVDVs) were isolated from cattle with mucosal disease or persistent infection in Japan. These isolates were compared for antigenic properties by cross-neutralization tests with Japanese reference strains of BVDV belonging to classical type 1.

Leukopenia and thrombocytopenia in pigs after infection with bovine viral diarrhoea virus-2 (BVDV-2).

DTW. Deutsche tierarztliche Wochenschrift, 2002
The aim of this study was to investigate whether bovine viral diarrhoea virus-2 (BVDV-2) is pathogenic for pigs, which organs become infected and whether or to which extent the virus is excreted into the environment. Ten pigs were observed for clinical reactions after infection with a BVDV-2 strain, that has been shown to be pathogenic in calves under ...

Comparison of serum concentrations and duration of BVDV 1, BVDV 2, BHV-1, BRSV, and PI3 virus-neutralizing antibodies in calves fed maternal colostrum or a colostrum replacer at birth

American Association of Bovine Practitioners Conference Proceedings, 2012
Providing newborn calves with high concentrations of neutralizing antibodies through colostrum is a key management strategy for the reduction of respiratory disease caused by BVDV, BHV-1, BRSV, and PI3 in young calves. When maternally-derived immunity decays, calves become susceptible to acute viral infection and disease. Duration of maternally-derived

Characterization of recombinant BVDV-2 vaccine prototypes based on packaged replicons and replication competent deletion mutants

2010
Vaccination against Bovine Viral Diarrhea Virus plays a major role in the obligatory German control program decided in 2008. Both kinds of vaccines licensed today for the use in cattle have disadvantages: MLV vaccines concerning their safety and killed vaccines concerning efficacy.

Acute BVDV-2 infection in beef calves delays humoral responses to a non-infectious antigen challenge.

The Canadian veterinary journal = La revue veterinaire canadienne, 2016
Immunosuppressive effects of an intranasal challenge with non-cytopathic bovine viral diarrhea virus (BVDV) 2a (strain 1373) were assessed through acquired and innate immune system responses to ovalbumin (OVA). Concurrent BVDV infection was hypothesized to delay and reduce the humoral response to ovalbumin (administered on days 3 and 15 post ...
