Molecular characterization of cytopathogenic (cp) bovine viral diarrhea virus (BVDV) strain CP Rit, a temperature-sensitive strain widely used for vaccination, revealed that the viral genomic RNA is about 15.2 kb long, which is about 2.9 kb longer than the one of noncytopathogenic (noncp) BVDV strains. Molecular cloning and nucleotide sequencing of parts of the genome resulted in the identifica...
BACKGROUND The timing of the initial spread of hepatitis C virus genotype 1a in North America is controversial. In particular, how and when hepatitis C virus reached extraordinary prevalence in specific demographic groups remains unclear. We quantified, using all available hepatitis C virus sequence data and phylodynamic methods, the timing of the spread of hepatitis C virus genotype 1a in Nort...
Molecular analysis of a cytopathogenic (cp) bovine viral diarrhea virus (BVDV) isolate (1741) obtained from a case of mucosal disease (MD) led to the identification of five different viral subgenomic RNAs in addition to a noncytopathogenic (noncp) strain (NCP 1741). For each of the subgenomes, a large internal deletion was found together with an inserted sequence encoding part of ribosomal prot...
The reaction mechanism of the NS3/NS4A protease with the NS4B/5A and NS4A/4B natural substrates has been investigated using the QM/MM (quantum mechanics/molecular mechanics) approach, and some calculations have been performed on the reaction with the NS5A/5B natural substrate. This study widely extends a previous contribution of our group on the reaction mechanism with the NS5A/5B substrate, th...
