title: [Pathogenicity of clinical strains of Pseudomonas aeruginosa].
abstract: The study of 208 Ps. aeruginosa clinical strains, introduced intraperitoneally into white mice, revealed the statistically significant prevalence of pathogenic cultures (87.5--100%). The pathogenic strains of Ps. aeruginosa were found to have statistically significant differences in their cultural and biochemical properties depending on the kind of clinical material: the strains isolated from blood formed mucoid colonies, the zones of hemolysis and thermolabile or thermostable alkaline phosphatase, and typing could be made in 100% of the isolated cultures; the strains isolated from material of closed cavities formed mucoid colonies and the zones of hemolysis; the pathogenic strains isolated from material of open cavities showed only a tendency towards greater activity in the formation of extracellular sline and greater capacity for the formation of clarification zones on yolk agar as compared with nonpathogenic cultures.
