Contact-haemolysin production by entero-invasive Escherichia coli and shigellae.

abstract：:Streptolysin O (SLO) is a potent cytolytic toxin produced by almost all strains of group A streptococci and is considered an important virulence factor for this organism. In this study we investigated the effect of allicin and aqueous garlic extracts on the haemolytic activity of SLO. All tested materials potentially ...
