[Level of colonization by Ureaplasma urealyticum of definite biovars in a group of women with different clinical symptoms].

To evaluate the level of U. urealyticum colonization of female urogenital tract, the method of the multiplex polymerase chain reaction (PCR) in the presence of two pairs of primers, corresponding to genes controlling U. urealyticum 16S rRNA and unique human osteopontin was used. The study of 93 clinical specimens showed no correlation between high colonization level and the presence of definite clinical manifestations of U. urealyticum infection. The determination of ureaplasmic biovars was carried out by the method of PCR in the presence of 3 primers corresponding to the multiple-banded antigen (MBA) gene. Biovar parvo was detected in 85% of the specimens, biovar T960 in 11% and both biovars were detected in 4% of the specimens. The biovar distribution in the groups of women with different clinical symptoms was approximately similar. U. urealyticum of biovar T960 occurred more frequently (33% of the specimens) only in a group of women with vaginal discharge characteristic of inflammation.
