[Serological survey on mycoplasma infection among three populations in Yunnan Province].

ABSTRACT

Mycoplasma infection in both female and male genital tract has attracted attention recently. 636 infertile and sterile cases together with 284 women with IUDs and 113 women with genital inflammatory complications after artificial abortion were detected through indirect hemagglutination test for serological survey on the frequency of ureaplasma urealyticum (Uu) and mycoplasma hominis (Mh) infection. Some of them were detected through isolated culture at the same time. Among the 636 infertile and sterile cases, the results showed that the antibody positive rate to mycoplasma was 26.10%. Among women with IUD, the antibody positive rate was 32.39%. However, the antibody positives rates among women with IUD shorter than three months were significantly higher than those prior to and three to twelve months after insertion of IUD (P < 0.01). Among the 113 women after abortion, the positive rate was 46.02%. The positive rates of the three groups were significantly different from the control group (P < 0.001), and the antibody titers to mycoplasma were significantly higher than that of the control group. It is suggested that mycoplasma infection is one of the important causes for infertility and causing complication of genital inflammatory symptoms after abortion.
