[Ureaplasma urealyticum infection in spontaneous abortion].

Ureaplasma urealyticum in aborted tissue and cervical mucus were examined in 40 women with spontaneous abortion (test group), 20 women of induced abortion and 20 healthy pregnant women (control group). The results showed that the positive isolation rate of ureaplasma urealyticum was significantly higher in the test group than that in the control group (55.0% vs 10.0%). The detection rate of ureaplasma urealyticum increased along with the number of spontaneous abortion. It indicated that ureaplasma urealyticum might be a cause of unexplained spontaneous abortion.
