Biosecurity and biocontainment of bovine viral diarrhea virus

Veterinary Clinics of North America: Food Animal Practice, 2004
Infection of cattle with BVDV results in a variety of clinical illnesses costly to the cattle industry worldwide. The reservoir and primary source of transmission is cattle born PI with BVDV after transplacental infection in early gestation. It is a challenge to determine with certainty whether or not BVDV is circulating among a herd of cattle.

Bovine viral diarrhea virus genomic organization

1991
In previous work, we developed a preliminary description of the genetic organization of the prototypic pestivirus bovine viral diarrhea virus (BVDV). In order to refine this genetic map and to further elucidate the gene products and expression strategy of this virus, we have generated a broad panel of sequence-specific antibody reagents.

Immunologic Response of Bovine Fetus to Bovine Viral Diarrhea Virus

American Journal of Veterinary Research, 1973
SUMMARY Intraperitoneal inoculation of a cytopathogenic strain of bovine viral diarrhea-mucosal disease (bvd-md) virus, National Animal Disease Laboratory (NADL) strain, was performed in bovine fetuses at different stages of development to study their immunologic response to this virus. Results of morphologic, immunochemical, and serologic examinations

Response of cattle persistently infected with noncytopathic bovine viral diarrhea virus to vaccination for bovine viral diarrhea and to subsequent challenge exposure with cytopathic bovine viral diarrhea virus

American Journal of Veterinary Research, 1985
SUMMARY Nine steers persistently infected with noncytopathic bovine viral diarrhea (bvd) virus were allotted into 3 groups (3 cattle/group). Cattle in group A were vaccinated with a modified-live bvd virus vaccine of porcine cell origin, cattle in group B with a modified-live bvd virus vaccine of bovine cell origin, and cattle in group C with a killed ...

Bovine Viral Diarrhea Virus: Global Status

Veterinary Clinics of North America: Food Animal Practice, 2010
Despite the success of regional bovine viral diarrhea viruses (BVDV) eradication programs, infections remain a source of economic loss for producers. The wide variation among BVDV results in differences in genotype, biotype, virulence, and types of infections. BVDV infect a range of domestic and wild ruminants. Clinical presentation varies depending on

Application of recombinant bovine viral diarrhea virus proteins in the diagnosis of bovine viral diarrhea infection in cattle

Veterinary Microbiology, 1997
The National Animal Disease Laboratory (NADL) vaccine strain of bovine viral diarrhea virus (BVDV) genes for gp48 and p80 were expressed in Escherichia coli. The BVDV-NADL gene for gp62 was integrated into a baculovirus genome for expression in Spodoptera frugiperda (Sf-9) insect ovarian cells. The antigenicity of baculovirus expressed BVDV protein was

Molecular biology of bovine viral diarrhea virus

Biologicals, 2013
Bovine viral diarrhea viruses (BVDV) are arguably the most important viral pathogen of ruminants worldwide and can cause severe economic loss. Clinical symptoms of the disease caused by BVDV range from subclinical to severe acute hemorrhagic syndrome, with the severity of disease being strain dependent.

Persistent infection with bovine viral diarrhea virus in an alpaca

Journal of the American Veterinary Medical Association, 2006
Abstract Case Description—A 2.5-month-old female alpaca that had been born prematurely was examined because of moderate mucopurulent nasal discharge and high rectal temperature. Clinical Findings—In addition to pyrexia and clinical signs of disease of the upper portion of the respiratory tract, the cria had inappetence and was in an unthrifty condition.

Bovine viral diarrhea virus infections in heterologous species

Animal Health Research Reviews, 2009
AbstractInfections with Bovine viral diarrhea virus (BVDV) are not limited to cattle, but may be detected in various species in the mammalian order Artiodactyla. Despite epidemiological evidence of BVDV infections in species other than cattle, current knowledge regarding the impact of BVDV on heterologous species is incomplete.

Diagnosis of Bovine Viral Diarrhea Virus Infections

Veterinary Clinics of North America: Food Animal Practice, 1995
Because of complex pathogenesis and insidious nature of BVDV infections, the laboratory diagnosis is an essential component of developing measures for the control and prevention of BVDV infections. The positive isolation of BVDV from animal submissions or from aborted fetuses should provide a strong indication for further epidemiologic investigations ...
