[Effect of haemolysin of Pseudomonas aeruginosa on Ehrlich ascites tumor cells].

Haemolysin of Pseudomonas aeruginosa exerts toxic effects upon the metabolism of Ehrlich ascitic tumor cells : morphological changes appear readily ; respiration is inhibited more slowly ; the lethal effect determined by intraperitoneal injection of tumor cells is neutralized. Inhibition with human normal sera is complete for the hemolytic action, but incomplete for the cytopathic action.
