If you needed further proof that Hepatitis B virusses are infecting man and animals all over the world, look no further. When six dead Maxwell’s duikers (Philantomba maxwellii), a small antelope, from Taï National Park, Côte d’Ivoire were examined, scientists found yet another novel hepadnavirus, the family of virusses that causes Hepatitis B infections.
Analysis placed the virus as a divergent member of the mammalian clade of orthohepadnaviruses, though its relationship to other orthohepadnaviruses remains uncertain. This represents the first orthohepadnavirus described in an artiodactyl (or even-toed ungulate), an order of mammals that includes pigs, peccaries, hippopotamuses, camels, chevrotains, deer, giraffes, pronghorn, antelopes, sheep, goats, and cattle. . The scientists have tentatively named this virus Taï Forest hepadnavirus.
The Taï Forest hepadnavirus is closely related to Hepatitis B Virus in woodchucks, the Hepatitis B Virus in arctic squirrels and Hepatitis B Virus in ground squirrels. These North American virusses now have a novel African family member.
