The prevalence of streptococcus agalactiae (group B) colonization in pregnant women at Thammasat Hospital.

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.

MATERIAL AND METHOD: 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.

CONCLUSION

All the isolates were sensitive to Ampicillin, Penicillin, Vancomycin and Cephazolin. Resistant was seen with Clindamycin (3%) and Erythromicin (1.5%).
