“Background: Dehydroepiandrosterone DHEA ), a steroid present throughout life, can induce an increase in resistance to vancomycin in methicillin-sensitive and methicillin-resistant clinical isolates of Staphylococcus aureus.”
“However, DHEA significantly (p < 0.01) slowed the rate of vancomycin killing of sarA–. Conclusion: These data indicate that sarA may play a role in DHEA-mediated protection from vancomycin killing of S. aureus.”
