Direct sequencing of PCR products was used to study the VP1 region of the
hepatitis A virus (HAV) genome (position 2199 to 2356) of nine strains
isolated from human stools collected during a hepatitis A epidemic (western
France, 1992), three strains from environmental samples (1990, 1991, and
1992), and two HAV cell culture isolates (the French strain CF53/Lyon and
strain CLF). These viruses differed from CF53/Lyon (genotype I) by between
1 and 10.3%, and results indicated the existence of two groups of strains
belonging to two different subgenotypes (IA and IB). With this sequencing
technique it was possible to monitor the epidemiology of HAV and study its
relations.
