Extracellular haemolysin of four Proteus penneri strains was characterized as a polypeptide of approximately 110 kD. The chromosomal DNAs of these strains cleaved with Hind III showed three fragments hybridizing with a DNA probe containing cloned haemolysin (hly) genes of Escherichia coli. The results presented here suggested that the haemolysin of P. penneri strains is chromosomally determined and similar to the alpha-haemolysin of E. coli.
