Description
Summary:Pregnant woman is exposed to many sexual transmitted infections (STI). Many of these infections may produce diseases in the fetus and newborn, and also alteration in the normal course of the pregnancy. Screening of asymptomatic cervical infection in pregnant woman and its relationship with the vaginal microbiota. 85 pregnant women without clinical cervicitis who consult in the routine pregnant control (47 patients) and women derived from STI service (38 patients). The samples were obtained from the vaginal fund sac and were analyzed with optic microscopy, cultures and PCR of Neisseria gonorrhoeae, Trichomonas vaginalis and Chlamydia trachomatis. 12,9% of the enrolled women were positive for C. trachomatis, 2,4% for T. vaginalis. In this study, we did not found N. gonorrhoeae. We observed 23,3% of patients with altered microbiota (bacterial vaginosis and intermediate microbiota) was positive for C. trachomatis. In this study, we found a high frequency of C. trachomatis infection, that correlates with the presence of altered microbiota. This high frequency would promote preventive strategies in the pregnant women routine controls.
