[Intensity of hemolysin and lecithinase production by Bacillus cereus strains isolated from food].
The study was carried out on the filtrates of cultures of 60 Bacillus cereus strains isolated from food products which caused food poisoning (20 strains), from patients (20 strains) and from food analysed in routine supervision. The strains isolated from food poisoning demonstrated a more pronounced haemolytic activity as compared with the strains from routine supervision. A lack of correlation was demonstrated between the intensity of lecithinase production and the intensity of reaction of rabbit ileum loop. No strict correlation was noted between the haemolytic properties and lecithinase activity.
