Blood agar medium with dialysis membrane mounted between two layers of agar was applied to study the haemolytic activity of 28 strains of Serratia marcescens . Two kinds of lytic substances differing with their ability to pass through dialysis membrane were found. Haemolytic activity was not detected in cell‐free filtrates from liquid cultures. The discrepancies between haemolytic activity in blood agar media and activity of liquid cultures were observed. Stable attachment of bacterial cells to the erythrocytes was not necessary to lysis. The possibility of extracellular haemolysin is discussed.
