FIGURE 1.
Dendrogram analysis of PFGE results showing the genetic relationships among the PFGE profiles and the presence of agr and SCCmec type among the 33 S. aureus clinical isolates. A phylogenetic analysis was conducted using the Sørensen–Dice similarity coefficient in association with the UPGMA algorithm as the grouping method. The dendrogram was evaluated by obtaining the cophenetic correlation coefficient with the Mantel test, which yielded an r-value of 0.9077. Antimicrobial susceptibility profile (ASP), multidrug-resistant (MDR), sensitive (S). The dotted line indicates that the clinical isolates that belong to subcluster 10 with >90% genetic similarity.
