[Vaginal colonization by genital mycoplasmas in pregnant and non-pregnant women].

To compare vaginal colonization by genital micoplasmas in pregnant and non pregnant women and to determine the association between pregnancy and colonization by these microorganisms, samples of exocervix an endocervix from pregnant (n = 80) and non pregnant (n = 65) women, from two health centers of Maracaibo, Zulia State, Venezuela were processed. The Mycoplasma-Lyo kit (bioMérieux laboratories) was used for the culture and identification of genital micoplasmas. In pregnant women, prevalences of 10% for M. hominis and 26.25% for Ureaplasma spp. were found; 35.38% for M. hominis and 20% for Ureaplasma spp. in non-pregnant, were obtained. Among the pregnant, Ureaplasma spp. was the most frequently isolated micoplasma, in symptomatic and asymptomatic; while in the non pregnant group, M. hominis was more common among the symptomatic patients; only one case (1.54%) was an asymptomatic carrier of Ureaplasma spp. The highest positivity percentages were obtained in primigravidas (48.71%) and during the second gestational trimester (34.21%). No statistically significant differences were found between vaginal colonization by genital micoplasmas according to age, number of pregnancy and gestational trimester; but they were found between the presented symptomatology and vaginal colonization by genital micoplasmas. Genital micoplasmas were isolated from gravid women at approximately the same recovery rate as in non-pregnant women; being M. hominis the most frequently isolated in non-pregnant women and Ureaplasma spp. in the pregnant group.
