Investigation of a dual fetal infection model with bovine viral diarrhoea viruses (BVDV)-1 and BVDV-2

Archives of Virology, 2011
Two studies were performed in pregnant heifers to determine whether inoculation with two bovine viral diarrhoea viruses (BVDV), one BVDV-1 and one BVDV-2, inoculated separately into either nostril, results in fetal infection with both viruses.

Efficacy of a combination modified-live IBR-BVD-PI3-BRSV vaccine + Mannheimia haemolytica toxoid against challenge with virulent BVDV-1b and BVDV-2 viruses in young calves 60 days of age

The Bovine Practitioner, 2021
Efficacy of attenuated (att) bovine viral diarrhea virus (types 1 and 2) as antigen fractions in a modified-live multivalent vaccine were evaluated following single, subcutaneous (SC) administration and intranasal (IN) challenge 35 to 38 d after vaccination, with either virulent BVDV-1b (Study 1) or BVDV-2 (Study 2) viruses in young calves.

Experimental Infection of Calves with Bovine Viral Diarrhoea Virus Type-2 (BVDV-2) Isolated from a Contaminated Vaccine

Veterinary Research Communications, 2003
A non-cytopathic strain of BVDV-2 was isolated from a batch of live infectious bovine rhinotracheitis (IBR) vaccine, and inoculated intranasally into four 3-month-old calves. Severe signs of disease developed by days 4 and 6 in three of the calves, free of BVDV and antibodies to BVDV, that had been exposed to the virus.

Experimental infection of pregnant ewes with bovine viral diarrhea virus type-2 (BVDV-2): effects on the pregnancy and fetus

Veterinary Microbiology, 2001
The reproduction effects of bovine viral diarrhea virus type-2 (BVDV-2) infection were investigated in ewes inoculated with a non-cytopathic BVDV-2 isolate at three stages of gestation. Virus inoculation was followed by a transient viremia, accompanied by a transient and mild hyperthermia and nasal discharge in a few animals.

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

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 ...
