摘要: Bovine Viral Diarrhea Virus (BVDV) polypeptides present in infected cells are the result of processing polyprotein translated from large single open reading frame BVDV genomic RNA. The presence these proteins was studied by radiolabeling under hypertonic conditions and with aid radioimmunoprecipitation. mapping suggests a complex pattern which involves cellular viral proteases. consistent absence 80k noncytopathic isolates that is different cytopathic biotypes BVDV. antigenic structure panel monoclonal antibodies (MABs) prepared against Singer isolate Neutralizing MABs were found to bind 56-58k polypeptide, providing evidence this glycoprotein on surface virion carries neutralization epitopes. Antigenic analyses reveals extensive heterogeneity among field isolates. used determine frequency escape mutants stocks Plaque-purified contain 10(-2.47).
