Introduction:

Streptococcus agalactiae, currently known as group B streptococcus (GBS) is the main microorganism that colonizes the genitourinary tract in pregnant women, causing serious consequences in the neonate, such as neonatal sepsis, pneumonia, and meningitis.

Objective:

To determine the prevalence of GBS in pregnant women at the Dr. Mario Catarino Rivas National Hospital in Honduras.

Materials and methods:

Descriptive, prospective, cross-sectional study. A total of 143 pregnant women between 34-40 weeks of gestation attended at the gynecology and obstetrics service of the Dr. Mario Catarino Rivas National Hospital in Honduras from January 2020 to June 2021 were enrolled. Cultures were developed following the methodology recommended by the Centers for Disease Control and Prevention and Strepto B chromID agar was added. Descriptive statistics were used for analysis.

Results:

The mean age of the pregnant women was 26 ± 7.4 years. The prevalence of GBS in the study population was 3.5%, with 5 positive cases.

Conclusion:

The prevalence of GBS colonization in pregnant women is variable and may not be associated with risk factors for colonization, resulting in neonatal and maternal health complications. This highlights the need for active search for group B Streptococcus in pregnant women.
