Plasma samples from 12 gorillas, six orang-utans and five chimpanzees were evaluated for antibodies against viral, rickettsial, chlamydial or mycoplasmal antigens, and circulating lymphocyte subpopulations were characterized by assay of surface markers. Antibodies that cross-reacted with the viral capsid antigen of Epstein-Barr virus were present in all 23 animals. Antibodies against the following agents were detected in > 25% of animals by species: hepatitis A virus (gorillas, orang-utans, chimpanzees); hepatitis B virus - HBs, HBc, HBe (chimpanzees); rubeola virus (gorillas, orang-utans); rubella virus (gorillas, urang-utans); mumps V antigen (gorillas); herpes simplex virus (gorillas); Coxiella burnettii (orang-utans). Percentages of circulating T and B lymphocytes were similar for all three species and approximated the levels observed in human peripheral lymphocyte populations.
