T-strain mucoplasmas and reproductive failure in monkeys.

T-strain mycoplasmas were isolated from the genital tracts of 3 genera of female monkeys: the talapoins, Miopithecas talapoin, the patas, Erythrocebus patas, and the macaques, Macaca fascicularis. The talapoins have not reproduced successfully for the past 2 yr. Fertility in the patas has also been reduced, with a high incidence of stillbirths and spontaneous abortions. The macaques were not permitted to breed.
