U parvum is usually the commonest species detected in various clinical specimens but U urealyticum is probably more pathogenic in conditions such as male urethritis. In humans,
both Mycoplasma and Ureaplasma species may be transmitted by direct contact; venereally through genital-to-genital or oral-to-genital contact, vertically from mother to offspring either at birth or in utero, or by nosocomial acquisition through transplanted tissues. U urealyticum and M genitalium are causes of non-chlamydial non-gonococcal urethritis in men.
