Sensibilité de 534 bacilles à Gram négatif d'infections urinaires en médecine ambulatoire à Cotonou (Bénin)

Summary A prospective study about the distribution and the sensitivity of 534 Gram negative bacilli isolated from urinary tract infections in office practice was done at Cotonou (Benin). Three major species were identified : Escherichia coli (36 %), Klebsiella spp (25 %), Proteus spp (13,9 %). The most of the strains presented a high level of resistance to ampicillin, cephalothine, tetracycline and cotrimoxazole, but the second and third cephalosporin generation (cefotixin, cefotaxime) were efficient against almost strains as well as imipenem, gentamicin and quinolones. The multiresistance (18 % of strains), concerned essentially Pseudomonas aeruginosa, Acinetobacter, Klebsiella and Enterobacter . Those results indicated that a periodical survey of sensibility of major pathogenic bacterial is useful of therapeutic choice and rational use of the antibiotics in office practice at Cotonou.
