Characterization of the immune response of cattle against non-cytopathic and cytopathic biotypes of bovine viral diarrhoea virus.
Cross-infection studies of normal calves infected with homologous pairs of non-cytopathic and cytopathic bovine viral diarrhoea virus (BVDV) showed significant differences in both humoral and cell-mediated immune responses against either biotype over a period of 5 months. Serological assays after primary intranasal inoculation showed striking significant (P < 0.05) differences between biotypes....
متن کاملAntigenic and genomic comparison between non-cytopathic and cytopathic bovine viral diarrhoea viruses isolated from cattle that had spontaneous mucosal disease.
Antigenic and genomic relationships between five pairs of non-cytopathic and cytopathic bovine viral diarrhoea (BVD) viruses isolated from cattle with mucosal disease were examined. Antigenic similarity was evaluated by studying the binding characteristics of 10 monoclonal antibodies (MAbs) directed against the gp53 BVD virus glycoprotein. The MAb binding match between members of the same virus...
متن کاملUnderstanding the Pathogenesis of Cytopathic and Noncytopathic Bovine Viral Diarrhea Virus Infection Using Proteomics
Bovine Viral Diarrhea Virus (BVDV) is a single-stranded RNA virus in the Pestivirus genus within the Flaviviridae family. BVDV infections are seen in all ages and breeds of cattle worldwide and have significant economic impact due to productive and reproductive losses (Houe 2003). Two antigenically distinct genotypes of BVDV exist, type 1 and 2 (Ridpath et al. 1994). BVDV of both genotypes may ...
متن کاملDetection and characterization of genetic recombination in cytopathic type 2 bovine viral diarrhea viruses.
In cytopathic bovine viral diarrhea virus genotype 1 (BVDV1) isolates, insertions are reported at position A (amino acid [aa] 1535) and position B (aa 1589). Insertions at position B predominate. In this survey it was found that in BVDV2, insertions at position A predominate. Possible reasons for this difference in relative frequency are discussed.
متن کاملMonoclonal antibody analyses of cytopathic and noncytopathic viruses from fatal bovine viral diarrhea virus infections.
A panel of monoclonal antibodies that recognize the two major glycoproteins of bovine viral diarrhea virus (BDV) was used to evaluate the antigenic relationship between cytopathic (CP) and noncytopathic (NCP) viruses isolated from cattle dead or dying from fatal BDV infections. Various unrelated BDV isolates were initially screened by indirect immunofluorescence with monoclonal antibodies direc...
