a species that has been isolated from the respiratory tract and central nervous system of newborns. It causes infections of the genitourinary tract, particularly urethritis; thought to be sexually transmitted and transmitted from mother to infant. The laboratory diagnosis is simplified through the use of urea-containng agar, permitting detection of the tiny colonies.
a sexually transmitted microorganism that is a common inhabitant of the urogenital systems of men and women in whom infection is asymptomatic. Neonatal death, prematurity, and perinatal morbidity are statistically associated with colonization of the chorionic surface of the placenta by Ureaplasma urealyticum. The mechanisms by which the unfavorable effects on pregnancy occur are not understood. There is no characteristic lesion in the fetus or newborn. Treatment involves oral tetracyclines administered for a period of at least 7 days.
Ureaplasma urealyticumT strain mycoplasma Microbiology A species of small gram-negative bacteria of the family Mycoplasmataceae that lack a cell wall and catabolize urea–to ammonia; U urealyticum resides in the genital tract and nasopharynx, is sexually transmitted, and causes nongonococcal urethritis, urethroprostatitis, epididymitis in ♂; UTIs, fetal wastage, chorioamnionitis, and ↑ infertility in ♀, URIs; CNS infections in neonates Management Tetracycline–eg, doxycycline; if resistant, erythromycin. See Mycoplasma hominis. Cf Mycoplasma pneumoniae.
