Proper treatment of this infection in pregnant women is an important public bealth issue. Our goal was to compare the efficacy of amoxicillin and erythromycin on treatment of asymptomatic acute and chronic chlamydia trachomatis infection in pregnant women. Material & Methods: A randomized cohort trial of pregnant women with chlamydia trachomatis IgM and IgG positive serum receiving care at two inner city, university - based prenatal clinics were randomly assigned to receive either oral amoxicillin, 500 mg three times daily for 7 days (case grouP 1), erythromycin 400 mg four times for 7 days (case group2) or placebo 500mg three times for 7 days(control group). Participants referred for retesting 4 weeks after initiation of treatment and the patients were followed till delivery.Patients with positive folllow up blood tests were crossed over into the alternate treatment and retested at a later visit. Statitical analysis was performed by using McNemar ,exact Fisher tests and chi square analysis. Results: 333 pregnant women were enrolled in this study and 92 chlamydia infected women (27.62%) completed the protocol. There was no significant difference between delivery gestational age of the groups (39.05, 38.72, 38.6 week) showing that chlamydia infection was not associated with preterm labor. Acute chlamydia infection rates before and after treatment in both amoxicillin and erythromycin groups were significantly different.The rates of acute chlamydia infection reduced from 83.87% before treatment to 35.48% after treatment (p M3 ER -
