Congo Red Agar screening of S. aureus isolates. CRA screening for S. aureus with a dry crystalline colony morphology, which was considered indicative for slime formation. (a) The black bar (not visible, 0%) represents MRSA (n = 72), the dark grey bar represents MSSA with MRSA associated MLST CCs (n = 75) and the light grey bar represents MSSA with MSSA associated MLST CCs (n = 81). Asterisks denote statistically significant difference P < 0.01 (a) and statistically significant difference of individual CCs versus all other associated MLST CCs (b) P < 0.01.
