Abstract

Staphylococcus aureus is the main source of the virulence factors, particularly hemolysins causing serious and fatal infections. The hemolysins were overexpressed in several bacterial species from various clinical sources indicating the actual problem of gene transfer. The highest expression level was detected in the hld gene comparison to hla, hlb and hlg. Furthermore, they all showed variable expression levels depending on the bacterial species and isolation sources. Finally, the presence of the hemolysin substrate such as blood in the bacterial culture media increased the expression level.
