Association of Mycoplasma hominis and Ureaplasma urealyticum with some indicators of nonspecific vaginitis.
The purpose of this study was to determine the isolation rates of Mycoplasma hominis and Ureaplasma urealyticum from three populations of women and also to relate the presence of these microorganisms with some indicators of nonspecific vaginitis. Three hundred vaginal swabs were taken from delivery, pregnant and control (not pregnant) women. Cultures were done in E broth supplemented with arginine or urea. M. hominis was isolated in 5% at delivery, 12% from pregnant and 5% from control women and U. urealyticum was isolated in 21%, 31% and 28% respectively. There was statistical difference in the isolation rate of M. hominis in pregnant women respect to the other groups. Both microorganisms were more frequently isolated in women with acid vaginal pH, amine-like odor in KOH test, clue cells and leucorrhea. M. hominis was isolated in 17% and U. urealyticum in 52% from women with nonspecific vaginitis. M. hominis was isolated in 2% and U. urealyticum in 13% from women without nonspecific vaginitis. Although the presence of clue cells and amine-like odor in KOH test have relationship with Gardnerella vaginalis, these tests could also suggest the presence of these mycoplasmas.
