Results of PBP2a latex agglutination test on MRSA biofilms. A PBP2a latex agglutination test was performed and interpreted according to the manufacturer’s guidelines. Shown are MRSA biofilm samples from an untreated control MRSA and culture treated with MIC ampicilin (0.05 mg/mL), which had moderate and strong agglutination, respectively. The three disks from right are of biofilms samples from cultures treated with 9EA-FC-B at these concentrations; 0.19 mg/mL, 0.38 mg/mL and 0.75 mg/mL (as indicated) showing a very weak agglutination with turbid background. The middle disk is of biofilm sample from culture treated with MIC 9EA-FC-B (3.00 mg/mL) is showing no agglutination.
