ELISA for Alpha-hemolysin (Hla) in Methicilin-resistant Staphylococcus aureus (MRSA)
Abstract
Anti-virulence agents against MRSA inhibit the production of disease-causing virulence factors, such as alpha-hemolysin, but are neither bacteriostatic nor bactericidal. Here we discuss a rapid method to screen for MRSA anti-virulence agents by measuring alpha-hemolysin production through ELISA. This protocol can be used with other alpha-hemolysin producing bacteria or for other excreted toxins to which antibodies exist.
