[Evaluation of 6 years of group B streptococcus (GBS) screening in near-term pregnant women].

Streptococcus agalactiae (GBS) is a significant cause of morbidity and mortality among newborns. Colonization frequently occurs in pregnant women, nearly all international recommendations suggest that all pregnant women must be screened for vaginal colonization at 34 to 37 weeks of gestation. The microbiological diagnostic modalities used to combat GBS had to be accurate and in short time frame. We reported a 6 years experience of GBS screening, comparing results of culture swab of prenatal vaginal specimens and newborns colonization or infection. The carriage rate of 13 to 14% of GBS in newborn was unchanged during all the study period.
