Supplemental Figure 1. Genetic relationship between 554 strains of S. aureus, including the type strain S. aureus ATCC® 25923, from five bacterial populations (A☐: hands of professional dentists; B■: dental clinic environment air; C○: bovine milk from cows with and without mastitis; D●: insufflator for milking equipment; and E⨯: milking environment air). UPGMA dendrogram (rjk = 0.84949: good concordance) generated from the genetic distance matrix53 and the genetic interpretation of the patterns MLEE.
