Abstract
As group B streptococci (GBS) prevalence varies from place to place and this organism is responsible for serious infections in newborns such as septicaemia and meningitis, the present study was carried out to find the prevalence of GBS in pregnant women and their neonates. From June 1998 to April 1999 a total of 317 pregnant women and their neonates were examined for GBS. GBS colonization rate was 2.52% and 1.26% in pregnant women and their neonates respectively. Four sites - viz. throat, external ears, external nares and stump of umbilicus from neonates were found to be equally colonized by GBS immediately after birth and at the time of discharge from hospital, except the umbilicus which was not swabbed at the time of discharge. None of the neonates developed GBS related sepsis. Selective broth medium (SBM) was found to be a superior transport method over Stuart transport medium and filter paper method. All the isolates were sensitive to Ampicillin, Erythromycin, Penicillin followed by Chloramphenicol 66.6% (12/18). All the strains were resistant to Gentamicin, followed by Tetracycline 94.4% (17/18) and Kanamycin 88.8% (16/18).
