[Epidemiology of Pseudomonas aeruginosa hospital infection in the Ivory Coast].
210 P. aeruginosa hospital strains isolated at Abidjan from pathological samples or contaminated material were studied by means of serotyping, biotyping, phage-typing and for their resistance to eleven antibiotics. 87% were classified into 14 serogroups: O:1, O:2, O:3, O:4, O:5, O:6, O:8, O:9, O:10, O:11, O:12, O:13, O:15, O:16. No strains were O:7 or O:14. The presence of an ortho-nitrophenyl beta-d-galactopyranoside hydrolase was demonstrated in 42 strains belonging to the serogroup O:11. Sixty-five phage-types were defined but 37% of strains were untypable by phages. The incidence of resistance to each tested antibiotic was as follows: carbenicillin 49%, mezlocillin 44%, ticarcillin 34%, azlocillin 25%, cefamandole 94%, latamoxef 15%, cefotaxime 41%, cefsulodin 32%, tobramycin 35%, amikacin 7%, gentamicin 39%. Thirty-eight strains were multiresistant to carbenicillin, mezlocillin, ticarcillin, azlocillin, and four strains to eleven antibiotics. These results are compared with data of the scientific literature on the epidemiology of hospital Pseudomonas infection.
