Ureaplasma urealyticum infection

Ureaplasma urealyticum is a species in the genus Ureaplasma noted for its lack of a cell wall. It is found in about 70% of sexually active humans.[1] It can be found in cultures in cases of pelvic inflammatory disease and is transmitted through sexual activity or from mother to infant during birth.[2]

Clinical aspects

Infection can manifest itself depending on age and gender.

Men

It had also been associated with a number of diseases in humans, including nonspecific urethritis, infertility,[3]


Infants

Pregnancy and birth can be complicated by chorioamnionitis, stillbirth, premature birth,[2] and, in the perinatal period, pneumonia, bronchopulmonary dysplasia[4] and meningitis.[5] U. urealyticum has been noted as one of the infectious causes of sterile pyuria.[6] It increases the morbidity as a cause of neonatal infections.[7]

Treatment

Doxycycline is the drug of choice, but azithromycin is also used as a five-day course rather than a single dose that would be used to treat Chlamydia infection;[8] streptomycin is an alternative, but is less popular because it must be injected. Penicillins are ineffective — U. urealyticum does not have a cell wall,[9] which is the drug's main target.[10][11]
