Typesinfectious disease

Ureaplasma urealyticum is a type of bacteria that can cause infection of the urinary tract and vagina. It can be passed from mother to infant during birth, or be sexually transmitted.[1] Ureaplasma urealyticum can be found in a majority of sexually active people,[citation needed] most of whom are asymptomatic.[2] It can also be found in cultures in cases of pelvic inflammatory disease. It is not a commensal of the healthy uterine or amniotic microbiome. Infection with U. urealyticum can contribute to neonatal infection and negative birth outcomes.

Presentation[edit]

Men[edit]

It had also been associated with a number of diseases in humans, including nonspecific urethritis, and infertility.[3][4]

Women and infants[edit]

Infection in the newborn is accompanied by a strong immune response and is correlated with the need for prolonged mechanical ventilation.[5] Infection with U. urealyticum in pregnancy and birth can be complicated by chorioamnionitis, stillbirth, premature birth,[1] and, in the perinatal period, pneumonia, bronchopulmonary dysplasia[6] and meningitis.[7] U. urealyticum has been found to be present in amniotic fluid in women who have had a premature birth with intact fetal membranes.[8][9]

U. urealyticum has been noted as one of the infectious causes of sterile pyuria.[10] It increases the morbidity as a cause of neonatal infections.[5] It is associated with premature birth, preterm rupture of membranes, preterm labor, cesarean section, placental inflammation, congenital pneumonia, bacteremia, meningitis, fetal lung injury and death of infant.[4] Ureaplasma urealyticum is associated with miscarriage.[11] In addition, this pathogen may latently infect the chorionic villi tissues of pregnant women, thereby impacting pregnancy outcome.[12]

Diagnosis[edit]

Treatment[edit]

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;[13] streptomycin is an alternative, but is less popular because it must be injected. Penicillins are ineffective — U. urealyticum does not have a cell wall,[14] which is the drug's main target.[15][16]
