Inhibition of slime production by alizarin.

Slime production was analyzed using Congo red agar plates. Three S. aureus strains (MSSA 25923, MSSA 6538 and MRSA) and a S. epidermidis strain were cultured with and without alizarin (20 μg/ml) on Congo red agar plates for 24 h at 37 °C. Four independent experiments were conducted and one set of representative results is shown. None represents non-treated controls.
