title: The prevalence of streptococcus agalactiae (group B) colonization in pregnant women at Thammasat Hospital.
abstract: BACKGROUND
  Group B Streptococci (GBS) is responsible for serious infections in newborns such as septicemia and meningitis.
  
  
  OBJECTIVE
  The present study was carried out to find the prevalence of GBS colonization in pregnant women and to determine the pattern of antibiotic resistance of the isolates.
  
  
  METHODS
  From November 2004 to February 2005, 406 pregnant women were examined for GBS.
  
  
  RESULTS
  GBS colonization rate was 16% in pregnant women, receiving antenatal care at Thammasat Hospital.
  
  
  CONCLUSIONS
  All the isolates were sensitive to Ampicillin, Penicillin, Vancomycin and Cephazolin. Resistant was seen with Clindamycin (3%) and Erythromicin (1.5%).
