Performance of RT-PCR in the detection of Streptococcus agalactiae in the anogenital tract of pregnant women.

Introduction: Infection with Group B Streptococcus (GBS) is the most frequent in the first weeks of life of a newborn. The identification of pregnant women with GBS colonization may reduce neonatal infection.

Methods: This cross-sectional study evaluated the performance of real-time polymerase chain reaction (RT-PCR) to detect GBS colonization in the anogenital tract of pregnant women.
