The complete genome sequences of hepatitis B virus (HBV) from 12 HBV-infected Yucpa Indians of Venezuela, a group with highly endemic HBV, were amplified and sequenced. The 12 isolates were closely related to each other, with 98·6–100% nucleotide identity. A phylogenetic tree based on the complete genome indicated clearly that they were genotype F. Three individuals had evidence of infection with two different HBV deletion mutants. In two individuals, a three amino acid deletion was identified just prior to the ‘a’ determinant loop of the S region. A third individual was infected with virus that contained a complete core reading frame and a population that contained a deletion in the middle of the core region. These results indicate that genotype F HBV is present in the Venezuelan Yucpa Amerindians and the complete genome sequence allowed the identification of two unique deletion mutants in a limited set of samples.

Loads Analysis

In order to determine whether geographical or species clustering accounts for the distribution of hepatitis B virus (HBV) in subspecies of chimpanzees in Africa, four complete chimpanzee HBV (ChHBV) genome sequences were obtained from eight hepatitis B surface antigen-positive wild-born chimpanzees from Cameroon, Republic of Congo and Gabon. The serological profiles of these chimpanzees corresponded to the acute or chronic highly replicative phase of HBV infection, as confirmed by high plasma HBV loads. Analysis of the sequence alignment of 256 aa (S region) from the eight HBV-infected chimpanzees allowed us to determine the HBV amino acid patterns specific to each chimpanzee subspecies and to their geographical origin. Phylogenetic analysis of both the S region and the complete genome confirmed this distinctive clustering of eight novel ChHBV strains within Pan troglodytes. The strong phylogenetic associations of ChHBV sequences with both chimpanzee subspecies and their geographical origin were therefore confirmed.
