[Epidemiological study on mycoplasmas colonization and infection in the female genital tract].
1309 cervical or vaginal specimens from females in various physiological periods and women with multiple sexual partners were examined for Ureaplasma urealyticum and Mycoplasma hominis from Feb. to May, 1990. Significantly, low carriage rates of U.urealyticum were found in the neonatal (28.57%), puerperium (26.51%) and postmenopause (30.00%) groups, whereas, pregnant women (more than 36 weeks) showed the highest incidence (73.20%). The recovery rate of U. urealyticum in girls with no history of sexual contact was significantly lower (38.30%) than that in married nonpregnant women (48.98%) and women with multiple sexual partners (71.74%). The incidence rate of the genital mycoplasmas was significantly affected by the type of contraception, the number of sexual partners, socioeconomic states, degree of cultural traditional, as well as hormonal status. Possible modes of transmission of genital mycoplasmas were also discussed.
