[Epidemiology of Pseudomonas aeruginosa in Mauritania: study of 239 strains of various origins].
239 strains (173 from hospital infections, 20 from carriers, 46 from animal infections and environment) were studied with regard to their serogroups, biovars, phage-types and drug-resistance. 82.2% of all strains were typable by specific immune sera and distributed in 15 serogroups (0:1, 0:2, 0:3, 0:4, 0:5, 0:6, 0:7, 0:8, 0:9, 0:10, 0:11, 0:12, 0:13, 0:15, 0:16). Among them, 8 were ubiquitous (0:1, 0:3, 0:4, 0:5, 0:8, 0:9, 0:11 and 0:16) and found in hospital patients, carriers, animals and environment. Thirty-five 0:11 strains and four no agglutinable strains produced an orthonitrophenyl beta-d-galactopyranoside hydrolase (ONPG +). Among 183 strains typable by phages of the Lindberg phage-typing system, 96 different phage-types were recognized. The proportions of the strains untypable by phages were 8.6% for animal strains, 23.6% for hospital strains and 55% for strains from carriers. The frequency of the resistance to each of eleven tested antibiotics was as follows: carbenicillin: 48%, ticarcillin: 12.2%, azlocillin: 9.1%, cefotaxime: 22.8%, cefsulodin: 27.4%, ceftazidime: 0.5%, latamoxef: 6.2%, gentamycin: 12.2%, amikacin: 15.4%, tobramycin: 12.5%, norfloxacin: 0%. However, 18.7% of hospital strains, 65% from carriers and 92.5% of animal or environmental strains were susceptible to all of these antibiotics. These results are compared with those from a previous report on epidemiology of P. aeruginosa hospital infection in Ivory-Coast (Dosso, Vieu et al., Bull. Soc. Path. exot., 1987, 80, 19-27) and with the data of the scientific literature.
