Methicillin-resistant (MRSA) and multidrug-resistant (MDRAB) present a serious challenge because of their capability to cause biofilm resistance to commonly used antibiotics producing chronic infections and hindering the process of wound healing. In the current study, we investigated the antibacterial activity of extracts (MeOH, and its fractions CHCl and -butanol) against multidrug-resistant MRSA USA300 and AB5057. In vitro, the MeOH extract and both fractions of significantly inhibited biofilm formation and disrupted previously established biofilm by MRSA and MDRAB at all the tested concentrations (0.

Fluoroquinolones are among the drugs of choice used to treat MRSA infections. This study aims to identify different mechanisms of fluoroquinolne resistance in local MRSA random sampling isolates in Cairo, Egypt.
