[Risk factors for group B streptococcal colonization in pregnant women at term: prospective study of 294 cases]. / Facteurs de risque du portage du streptocoque du groupe B chez la femme enceinte à terme: étude prospective à propos de 294 cas.

OBJECTIVE: To determine the rate and risk factors for group B streptococcus (GBS) colonization in term pregnancies. PATIENTS AND METHODS: Vaginal and anal cultures were prospectively conducted in 294 parturient on admission for term vaginal delivery. RESULTS: Thirty-eight (12.92%) parturient had positive GBS cultures. None of the studied risk factors (age, education status, nulliparity, previous obstetric problem, twin pregnancy and diabetes) was statistically predictive of maternal colonization. All the isolated GBS were sensitive to the penicillin G. DISCUSSION AND CONCLUSION: Systematic screening strategy of GBS close to the delivery on all pregnant women is desirable.
