Recombinant hepatitis C virus in experimentally infected chimpanzees Free

Abstract

Genetic recombination between different strains of (HCV) was investigated in three chimpanzees inoculated experimentally with factor VIII concentrate containing HCV subgenotypes 1a, 1b, 2b and 3a. A 750 bp long fragment from the HCV envelope region was amplified by RT-PCR and quasispecies were isolated by plasmid cloning. Nucleotide sequences derived from isolated quasispecies were screened for the presence of inter-subgenotypic recombination by using sequence analysis. Recombination between HCV subgenotype 1a and 1b was found in two animals; each recombinant variant differed by location of predicted crossover region or order of subgenotype 1a and 1b sequences.
