Genital Ureaplasmas in nonhuman primates.

Ureaplasmas were isolated from the genital tracts of four of 22 (18.4%) male chimpanzees and eight of 23 (34.8%) female chimpanzees. Twenty-nine female rhesus monkeys, 38 female baboons, one gibbon, and black ape and one Java monkey were shown to be free of genital Ureaplasmas. The rate of reproductive failure among the chimpanzees was high and it is suggested that Ureaplasma may be responsible in part. The chimpanzee may serve as a useful model for human Ureaplasma genital infections.
