    The recent isolation of  a nonhuman  primate hepadnavirus  from woolly monkeys  prompted  an examination of other primates for potentially new hepadnaviruses. A serological analysis of 30 captive gibbons revealed that 47% were positive for at least one marker of ongoing or previous infection with a hepatitis B virus (HBV). The amino  acid sequences  of the  core and  surface genes  of human  and gibbon  virus isolates  were very  similar. Phylogenetic analysis indicated that the gibbon isolates lie within the human HBV family, indicating that these HBV isolates most likely stem from infection of gibbons from a human source.
