Epidemiology of clinical and environmental Pseudomonas aeruginosa strains

Abstract – 296 strains collection of Pseudomonas aeruginosa isolated from the hospital environment (100), marine water (119) and mineral water (77) were identified and con-firmed by 26 biochemical, physiological and metabolic tests. This identification was deep-ened by three epidemiological markers: antibiotyping, serotyping and pyocinotyping. The biochemical and epidemiological studies showed that the clinical strains and the mineral water ones are closely related: (i) the dominant hospital serotypes are O: 1, O: 4, O: 10 an
