FIG. 1.

Dendrogram based on PFGE SmaI restriction pattern analysis of 51 nares-colonizing S. sciuri isolates. Similarity analysis was performed with Dice's coefficient, and clustering was done by using the unweighted-pair group method using average linkages (UPGMA) method. The scale at the top shows percentages of similarity. Further information is shown on the right, including the presence (pos) or absence (neg) of the S. aureus mecA gene (Sau), positive (pos) or negative (neg) Slidex Staph Plus agglutination test (Slidex) results, presence (pos) or absence (neg) of the S. sciuri mecA gene (Ssc), and results of 16S rRNA gene sequencing (16S). The rectangle highlights a clustering of S. aureus mecA-positive S. sciuri strains.
