Inhibition of Colony-spreading Activity of Staphylococcus Aureus by Secretion of Delta-hemolysin


Background: Staphylococcus aureus spreads on soft agar surfaces, a phenomenon called “colony-spreading”. Results: We purified delta-hemolysin from S. aureus culture supernatant as an inhibitor of colony-spreading, and its disrupted mutant had high colony-spreading ability. Conclusion: S. aureus negatively regulates colony-spreading by secreting delta… (More)
