 AB    Hepatitis C virus quasispecies in six patients from three families were
       separated by single strand conformation polymorphism analysis and by
       determination of nucleotide sequences of envelope regions containing the
       E1 gene segment and hypervariable region-1 of each quasispecies. Four of
       the six patients had multiple quasispecies. Phylogenetic analyses
       indicated that all quasispecies from one individual were highly
       homologous to each other. The homology was higher in the E1 gene segment
       than in hypervariable region-1. Furthermore, all quasispecies found in
       members of one family (husband and wife) were also highly homologous,
       suggesting direct intrafamilial transmission. The direction of hepatitis
       C virus variation in hypervariable region-1, however, seems to differ
       depending on the host in intrafamilial transmission.
