[Frequency of Chlamydia trachomatis in the cervix of pregnant women during prenatal examinations].

From February 1993 to October 1995, 80 endocervical samples taken from 80 pregnant patients in pre-natal control were examined in private practice at the Hospital Angeles del Pedregal in Mexico City for purposes of detecting Chlamydia trachomatis by direct inmunoflorecency. Gestational ages ranged from 20 to 39 week. A positive reaction to Chlamydia trachomatis was observed in 10% (8 patients) of the participating patients. Taking into account this frequency it is suggested that this study be a part of prenatal control.
