title: [Vaginal colonization by group B streptococcus among pregnant women in the region of Marrakech].
abstract: BACKGROUND
  Group B streptococcus is the main etiological agent of maternal and fetal infections, sepsis and meningitis in the term newborns. The objective is to determine group B streptococcal (GBS) carriage rate in vagina of term pregnant women.
  
  
  METHODS
  Vaginal swab was performed prospectively in 275 pregnant women in labor, prior to entering the delivery room over a period of 6 months.
  
  
  RESULTS
  Colonization rate was 20.2%. The bearing was variable according to the gestational age, it constitutes 57.5% between 37 and 38 weeks of amenorrhoea. None of the risk factors was statistically predictive for maternal GBS colonization.
  
  
  CONCLUSIONS
  Screening should be performed from 37 weeks of amenorrhoea and, as colonization is intermittent, a negative swab result does not ensure that GBS colonization is eradicate at birth.
