ABSTRACT

Background: Amniotic fluid has a bacteriostatic effect that inhibits bacterial growth, maintains a sterile environment for the fetus, and avoids the growth of vaginal microorganisms. Amniocentesis is a procedure to obtain amniotic fluid, allowing the study of the fetus and the amniotic environment.
Objective: To know the correlation between microorganisms found in cultured amniotic fluid obtained by amniocentesis with those reported in cultures of cervicovaginal secretions in patients with a diagnosis of preterm labor.
Patients and methods: A prospective cross-sectional study in which cultured amniotic fluid obtained by amniocentesis from 84 pregnant patients with a diagnosis of preterm labor between 24-34 weeks gestation at the Hospital Regional Adolfo López Mateos during the months from January to December 2012. The blood agar culture media, and Sabouraud agar were used, as well as the culture of cervicovaginal secretions which is looking forward to correlate the findings of both studies
Results: We found that 65 patients (40.6%) were nulliparous and 19 (59.4%) multiparous. The results of cultures of amniotic fluid were negative in all 84 patients (100%). Normal flora was found in cultures of cervicovaginal secretions in 39 (46.4%). In 45 cases (53.5%) positive cultures were reported: 40 cases (88.8%) with Candida albicans, and 5 (11.1%) with Escherichia coli.
Conclusions: no correlation was observed between the presence of microorganisms that grew in the amniotic fluid with those found in cervicovaginal secretions. There are other simpler and cheaper tests that can be performed quickly and may be more useful in the early diagnosis of amniotic infection.
