Streptococcus agalactiae has great medical importance in infections associated with severe neonatal morbidity and mortality. It is the most frequent bacterium isolated from the tables of septicemia, pneumonia and neonatal meningitis. This study aimed to determine the prevalence of anal and vaginal colonization of S. agalactiae in pregnant women at different gestational ages. We evaluated the incidence of colonization by S. agalactiae in 129 pregnant women of any age. Two samples of secretion were collected for culture: a perianal swab and a vaginal swab. Each of the two swabs were inoculated in test tubes containing Todd-Hewitt broth and subcultured on blood agar. After a period of 24 to 48 hours, the colonies suggestive of S. agalactiae were submitted to morfotintorial analysis and to biochemical tests for identification. Among 129 women studied, 3 (2.33%) have tested positive for Streptococcus agalactiae and 126 (97.67%) were negative. The results presented in this work are inferior to the data from other studies, however, the methodology used was compatible with most authors. Even so this rate is considered a relevant value taking into account the importance of Streptococcus agalactiae infections in pregnant women and newborns, emphasizing the importance of encouraging the culture of vaginal and anal secretion for the detection of Streptococcus agalactiae in surveys of prenatal care.
