title: Phylogenetic characterization of genotype 4 hepatitis C virus isolates from Argentina.
abstract: Among 114 patients infected with hepatitis C virus, three genotype 4 isolates, unusual in Argentina, were detected by phylogenetic analysis over different genomic regions. The patients were not related. One sample was associated with Egyptian sequences, and the others were associated with a Zairean isolate, a fact which reinforces the idea that they are from independent sources.
