Prevalence of Group-B streptococcal (GBS) infection varies from place to place and this organism is responsible for serious infections in newborns such as septicemia and meningitis. The present study was carried out to find out the prevalence & antibiotic sensitivity of GBS in primigravida & to identify the risk factors. 300 pregnant women were studied attending the antenatal clinics in Government Maternity Hospital, Tirupati. Two vaginal swabs were taken from each pregnant women. The two swabs were immediately transported to the laboratory for processing. Direct Gram stain was done from one swab and the other swab was inoculated onto sheep blood agar plate and incubated at 37ºC for 24-48 hours. Identification was done based on Gram staining, colony morphology, catalase reaction, CAMP test and Hippurate hydrolysis test & Bacitracin resistance. Of the 300 pregnant women screened, 7% were colonized by GBS. GBS colonization rate was higher among pregnant women in third trimester who were < 25 years of age. All the isolates were sensitive to Penicillin, Ampicillin, ceftriaxone, levofloxacin and vancomycin. GBS colonization rate among pregnant women in third trimester of pregnancy is low in this area. Revised guidelines from the Centers of Disease Control and Prevention (CDC), 2010 for the prevention of perinatal GBS disease recommends that all pregnant women be screened for GBS carriage between 35 and 37 weeks of gestation and intrapartum antibiotic prophylaxis be given to colonized women at the time of labour onset or rupture of membranes.
