Background Reproductive tract infections (RTIs) in pregnancy are an important cause of fetal and neonatal morbidity, sometimes with serious complications. Chlamydia trachomatis causes ectopic pregnancy, conjunctivitis, pneumonia and RTIs in newborn babies. Listeria monocytogenes and Streptococcus agalactiae can give neonatal sepsis and meningitis, and Trichomonas vaginalis causes premature birth. Objectives To update local epidemiology of RTIs in pregnancy in order to to implement efficacious screening and prevention programs. Methods Between January- December 2006, at the Padua’s Hospital Microbiology and Virology Service,we investigated 2000 asimptomatic pregnant women, 18-45 years old, Italian and foreigners.We collected vaginal and cervical swabs for the microscopy, the culture for Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma spp., Streptococcus agalactiae, Listeria monocytogenes, and other bacteria and yeasts, and for the molecular assay for Chlamydia trachomatis. Results The prevalence of Chlamydia trachomatis and Trichomonas vaginalis in our population were 2.06% and 0.20%, respectively. Neisseria gonorrhoeae was not detected. Sexually transmitted infections (STIs) were more frequent among foreigners, and in women aged 18-30.The prevalence of Streptococcus agalactiae was 8.69% for Italian, and 7.54% for foreigners.We didn’t find any case of maternal colonization by Listeria monocytogenes. Conclusions From the obtained results ideas have emerged to arrange a qualitative and quantitative optimization of the diagnosis of RTIs, implementing diagnostic paths based on the different typologies of patients and on the local epidemiology. The cultural research of Listeria monocytogenes takes a long time, perhaps a molecular one, because of fastness and sensitivity, could be more useful.
