Identification of source and sink populations for the emergence and global spread of the East-Asia clone of community-associated MRSA

Table 1 Antibiotic resistance genes associated with presence in the East Asia ST59 clade and absence in the USA ST59 clade

Gene associated with presence in East Asia clade and absence in USA clade	Antibiotic(s) to which resistance conferred
catA	Chloramphenicol
ermB	Macrolides, lincosamides, streptogramins B
mecA	Beta-lactams
tetK	Tetracyclines
ant(6)-Ia	Aminoglycosides
aph(3)-III	Aminoglycosides

Presence of genes was determined by mapping short read sequence data to a database of reference genes using the method described in [57]. The distribution of antibiotic resistance genes across the CC59 isolates is depicted in Fig. 4
