Eight strains of Escherichia coli, isolated from patients with a urinary tract infection were investigated for production of hemolysin. Six of these produced hemolysin and one revealed maximum hemolytic activity. Three urinary and two faecal isolates were positive for mannose-resistant hemagglutination. One isolate positive for hemagglutination and giving maximum hemolytic activity was then used. Hemolysin was present in the supernatant broth and the medium of choice to obtain the optimum yield was the alkaline meat extract broth followed by brain heart infusion broth. The highest yield appeared in the exponential phase of growth. Hemolysin is a heat-labile protein, being produced optimally at pH 8. A three-stage procedure was the best method for its purification.
