Detecção do Streptococcus agalactiae realizado no Hospital Universitário de Santa Maria

Abstract

The cervical-vaginal colonization in pregnant women favors the early-onset of neonatal infection wath may cause septicemia, meningitis and pneumonia in newborns.This study has as its objective to verify the detection rates of Streptococcus agalactiae in adult patients who were seen at Hospital Universitário de Santa Maria (HUSM), Rio Grande do Sul, in the period of 2007 to 2010. It was also carried out a data survey concerning the guides, Centers for Disease Control and Prevention, published in the years 1996, 2002 and 2010, to future prevent the neonatal disease caused by the Group B Streptococcus . It was evaluated the prevalence of vaginal and rectal S. agalactiae colonization in pregnant women at the HUSM Obstetric Center from June to December 2009. The Streptococcus agalactiae positive urine cultures from patients seen at the HUSM in the period of 2007 to 2010 were evaluated as well. This study found a prevalence of 11,11% in vaginal and rectal S. agalactiae colonization in pregnant women and, among all positive cultures (6,190/34,988), the GBS was isolated in 1,52% (94/6,190) of the samples. An equal proportion was found among pregnant and non-pregnant ones. 40,4% of these women presented a score of ≥105 Colony Forming Units per milliliter of urine (CFU/mL), 53,57% , between 104 -105 CFU/mL and 6% had a score smaller than 104 CFU/mL. All GBS which were submitted to analysis were sensitive to penicillin and ampicillin.
