Prevalence of Beta-hemolytic Group B Streptococcus in pregnant women with threatened preterm labor

Abstract

Objective: To determine the prevalence of Beta-hemolytic Group B Streptococcus (GBS) in pregnant women with threatened preterm labor, due to the limited research in Peru regarding this topic. Material and methods: Swabs of both rectum and lower third of the vagina were taken from pregnant women with threatened preterm labor diagnosis that were hospitalized in the Pathological Pregnancy Unit at the Hospital Daniel Alcides Carrion, between August and November 2015. All samples were carried in AMIES transport medium and taken to the microbiology laboratory for culture. Results: GBS was not isolated in any of the 30 pregnant women who took part in the study. 60% of the samples were positive for E. coli, 6.7% for Enterobacter aerogenes and Gardenella vaginalis, and 3.3% for Klebsiella pneumoniae, and 23% had normal vaginal flora. Conclusions: None of the participants in this study presented Group B streptococcus colonization.
