title: Haemolytic activity of Morganella morganii strains.
abstract: Haemolytic activity on solid and liquid media of 103 Morganella morganii strains isolated from clinical sources was investigated. The ability to produce haemolysin was found in 42.7% of strains. All strains capable to produce haemolysin on blood agar media also revealed haemolytic activity in some liquid media. Haemolysins were found in the supernatants and filtrates of the cultures in peptone water but not in Brain Heart Infusion and Trypticase Soy Broth. The maximal titer of haemolysin was observed in the logarithmic phase of growth. Heating and incubation with trypsin led to complete loss of haemolytic activity.
