[Characteristics of selected virulence factors of Enterobacter cloacae strains isolated from clinical specimens].
We demonstrated that Enterobacter cloacae possesses a selective haemolytic activity on sheep erythrocytes. All the screened strains showed a haemolytic activity on sheep erythrocytes when cultures were preincubated with beta-mercaptoethanol. The investigation circulation of the genes encoding extended spectrum beta-lactamases (ESBL) shows that beta-lactamase producers can be ascribed to specific patterns of plasmids. We also demonstrated that genetic material from E. coli can be transferred and established in selected Enterobacter cloacae strains. In a survival tests we demonstrated that similarly to Salmonella or Vibrio clinical isolates Enterobacter cloacae doesn't demonstrate acid tolerance.
