Isolation of Chlamydia trachomatis from amniotic fluid.

Abstract

A 26-year-old white woman had premature rupture of membranes at 35 weeks' gestation. Cervical specimens initially demonstrated group B streptococci and Chlamydia trachomatis. Amniocentesis was performed and the amniotic fluid was positive for chlamydia by direct fluorescent antibody stain. The Gram stain was negative. The patient had an elevated white blood cell count. Labor was induced because of suspected chorioamnionitis. A 2120-g female infant was delivered with an Apgar score of 9 at 1 and 5 minutes. The infant's eye and nasopharyngeal specimens were positive for chlamydia by direct fluorescent antibody stain. After delivery, both Ureaplasma urealyticum and C trachomatis were isolated from the amniotic fluid and fetal membranes. This is the first reported case of chlamydial isolation in amniotic fluid.
