title: [Hemolytic activity of Klebsiella pneumoniae and Klebsiella oxytoca].
abstract: We demonstrated that Klebsiella pneumoniae and Klebsiella oxytoca possess a selective haemolytic activity on rabbit erythrocytes. Thirty one Klebsiella strains (18 strains of K. pneumoniae and 13 strains of K. oxytoca) were isolated from hospitalized patients. The liquid (Trypcase-soy broth--TSB) and solid (Trypcase-soy agar--TSA) medium, containing the red cells were used for the tests. All the screened strains showed a haemolytic effect on rabbit erythrocytes, provided that the supernatants of the cultures were preincubated with beta-mercaptoethanol or calcium chloride. There was no human and sheep erythrocyte lysis.
