SUMMARY SUSCEPTIBILITY OF GRAM-NEGATIVE B ACILLI STRAINS ISOLATED FROM URINARY-TRACT INFECTIONS IN OFFICE PRACTICE AT COTONOU (BENIN)

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 identif ied : 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 seco nd and third cephalosporin generation (cefotixin, cefotaxime) were eff icient against almost strains as well as imipenem, gentamicin and quin olones. The multiresistance (18 % of strains), concerned essentially P seudomonas aeruginosa, Acinetobacter, Klebsiella and Enterobacter. Tho se 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.
