Unusual Colonies of 'Ureaplasma Urealyticum' (T Mycoplasmas) in Primary Agar Cultures of Certain Urine Specimens.

摘要

The existence of unusual colonies of Ureaplasma urealyticum (T mycoplasmas) in primary agar cultures of certain urine specimens is reported and their morphology is illustrated. The occurrence of such unusual colonies of U. urealyticum in agar cultures of urine specimens from only certain male NGU patients is believed to be associated with elevated levels of certain divalent cations (magnesium and manganese, for example) and increased concentrations of urea. These small, unobtrusive, unusual, naturally occurring accretion colonies of U. urealyticum may easily be overlooked and unrecognized in primary agar cultures of urine specimens from certain male NGU patients.
