[Prospective epidemiologic study of group B streptococcus vaginal colonization in pregnant woman]

ABSTRACT

Group B streptococcus is known to be the principal medium responsible of maternal and severe neonatal infection. Assessing the prevalence of group B streptococcus [GBS] in our population, emphasize risk factors of GBS vaginal colonization and main characteristics of isolated strains. Prospective study of GBS vaginal colonization at admission for delivery upper to 34 amenorrhea weeks. Two hundred and seven vaginal swabs were carried out. Prevalence of GBS was 13%. Primigravida represents a risk factor of GBS vaginal colonization regarded to multigravida. False negative rate was 1,6%, All isolated strains were susceptible to penicillin C and to ampicilin, 44,4%were resistant to erythromycin. Systematic screening of GBS must be introduced in our population. Per partum antibioprophylaxis must consider susceptibility of isolated strains to antibiotics
