Fig. 1. Phylogram depicting the relationship between the environmental and clinical HAV strains in relation to other isolates characterized previously over a 296 bp fragment of the VP1/2A junction region. Scale represents genetic distance. The internal node numbers represent bootstrap values (100 replicates) expressed as the percentage of all trees. Values greater than 70 % indicate statistically significant grouping (Felsenstein, 1985).
