title: [Group B streptococcus screening: a retrospective study in 1,674 pregnancies].
abstract: OBJECTIVE
  To evaluate our clinical practice for Group B streptococcus (GBS) screening during pregnancy and antibiotic therapy during delivery.
  
  
  METHODS
  We performed a retrospective evaluation of our SBS screening protocol, by vaginal swab, for a period of two years, including 1,674 asymptotic patients. Intra partum antibiotic prophylaxis was administrated for GBS-positive women.
  
  
  RESULTS
  The rate of GBS carriage was 6.9%. Antibiotics were administrated for 79.3% patients with GBS-positive culture. Of these women only 39% had an interval greater than four hours between antibiotic injection and delivery. In the group of patients with positive GBS culture, no newborn was infected and only 5% were colonised. In the GBS-negative group with 1.3% of the newborns were GBS positive.
  
  
  CONCLUSIONS
  We were surprised by our low rate of GBS carriage and the non optimal application of antibiotics during labor. We reviewed our results with all our team and a prospective evaluation has been initiated.
