Swabs were cultured from the lower vagina and anorectum for GBS using Todd-Hewitt broth with nalidixic acid 15 microg/ml and gentamicin 8 microg/ml only. RESULTS: Colonization was present in 58 cases (18.12%). The risk factor for GBS colonization was an older mean maternal age and a lower mean gestational age. No mothers or neonates during the study period developed a clinical infection from GBS. CONCLUSION: The risk factors for GBS colonization in pregnant women were older maternal age and lower gestational age.engAdolescentAdultAge FactorsChildCross-Sectional StudiesFemaleGestational AgeHumansObstetric Labor Complications --diagnosisPregnancyPregnancy Complications, Infectious --diagnosisRisk FactorsStreptococcal Infections --diagnosisStreptococcus agalactiae --geneticsThailand --epidemiologyJournal Article
