Abstract

No orthodox practices disrupt the vaginal flora and expose it to pathogenic microorganisms including group B Streptococcus β hemolytic (GBS). The study aims to describe the bacterial profil and resistance of GBS to antibiotics. Retrospective study included 640 women at Cotonou suspected of vaginal infections or vaginal discharge during 1st January 2004 to 31st December 2015. Three swabs were collected and analyzed to identify the bacteria by standard biochemical reactions, diagnosis of bacterial vaginosis and identification of Trichomonas vaginalis, yeasts and leukocyte count. Antibiogram was performed according to the CA-SFM. Among 640 samples, 502 (78.4%) were positive. The most encountered microorganisms were Candida albicans (37.45%) and GBS (19.92%). GBS sensitivity ranged from 80-100% for augmentin, pefloxacin and nitrofuran. But resistance was observed to netilmicin, tetracyclin, cefoxitin, cephalotin, thiamphenicol, trimethoprim / sulfamethnoxazole between 80-100%. A high percentage of resistance is the result of uncontrolled access to antibiotics and improper antibiotic policy. Routine susceptibility testing will allow to take appropriate treatment of GBS in Benin.
