非人类的灵长目动物也可感染乙型肝炎,如伦敦动物园中黑猩猩曾发生乙型肝炎爆发流行。当时对2头猩猩作血清学检测,其中1头抗-HBs 阳性,但猩猩患活动性乙型肝炎尚未见报道。作者认为,灵长目动物乙型肝炎感染有与人群乙型肝炎感染相似的家庭集聚性。1980～1982年,对美国辛辛那提动物园中的猩猩进行了研究。1980年1月21日,该动物园中的1头雄 Non-human primates can also be infected with hepatitis B, such as chimpanzees in London zoos have had a prevalent hepatitis B outbreak. Two orangutans were tested for serology at that time, of which one was positive for anti-HBs, but active hepatitis B in orangutans has not been reported yet. The authors suggest that primates have similar home-onset hepatitis B infection in their populations of hepatitis B infection. From 1980 to 1982, the orangutan in the Cincinnati Zoo was studied.
