Fig. 1.

Polyphasic comparison of S. aureus clinical isolates. a Colored similarity matrix categories representing resistant test against different antibiotics (ART), biochemical test, PCR based mecA and pvl genes detection, SCCmec typing, coa-HaeIII RFLP, spa type, biofilm-forming assay and detection of biofilm-associated genes. Red and blue colors indicate the presence ( +) and absence (−) of particular properties respectively. b NJ-dendrogram prepared from the results of biochemical and molecular analysis of the 15 S. aureus clinical isolates (SA). The isolates were labeled according to their geographical origin where G and H indicate Germany and Hungary. Clusters are labeled as A-F. c Principal component analysis of the results of biochemical and molecular analysis of the 15 S. aureus clinical isolates
