[The microbiological and pathomorphological characteristics of Klebsiella infection].

Biological properties of 350 strains of Klebsiella pneumoniae isolated in newborns during the outbreak of intrahospital infection have been studied. Experimental infection with isolated strains of a similar plasmid profile is simulated, interrelation between the presence of plasmids and ability of the strain to induce generalized Klebsiella infection is shown. Pathological processes in the newborns with generalized infection and in animals with the reproduced experimental Klebsiella infection are shown to be similar in principle.
