Agr activity and biofilm formation differences among mecC-MRSA belonging to clonal complex 130. (a) Macroscopic camera image of an S. aureus isolate (mecC-MRSA) harbouring the agr III wild type (wt) variant (IMT38119) grown in a 24-well plate and (b) the confocal laser scanning picture showing the biofilm profile at the indicated spot (red square). (c) Isolate harbouring a agr III variant (non-wt agrC variant) lacking agr activity (RKI5966) and (d) its corresponding biofilm. (e) Isolate lacking agr activity (IMT31819) and (f) its corresponding biofilm.
