Isolation of genital mycoplasmas and Chlamydia trachomatis in stillborn and neonatal autopsy material

Abstract

Chlamydia trachomatis and the genital mycoplasmas are significantly prevalent in sexually active women. How these organisms may affect the outcome of pregnancy and the neonate was the principal thrust of this investigation. Placenta, liver, and lung tissue were cultured from Mycoplasma hominis, Ureaplasma urealyticum, Chlamydia trachomatis, and aerobic as well as anaerobic bacteria in 432 stillborn and neonatal autopsies. Genital mycoplasmas were isolated from 36 cases (8.3%). Acute chorioamnionitis and funisitis were present significantly more often in cases with genital mycoplasma than in those without these organisms. Isolation of genital mycoplasmas was not associated with an increased incidence of intrauterine fetal death, villitis, hyaline membrane disease, congenital anomalies, or polymorphonuclear leukocytes in alveolar spaces. Chlamydia trachomatis was not found in any of the sites sampled.
