Analysis of virulence gene profiles of 103 Chinese Staphylococcus aureus isolates from bovine clinical mastitis. This dendrogram was generated based on the presence/absence of virulence genes with the sum of branch length = 0.91629109. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. (a-e) refer to different virulence gene clusters. Blue boxes indicate the presence and yellow boxes the absence of the corresponding virulence genes, and the number on the right refer to the virulence profile patterns, whereas the number under the box refer to the corresponding number of positive isolates in each virulence gene. (a-q), refers to the virulence genes in order: hla, hlb, hlc, hld, clfA, clfB, fnbA, fnbB, icaA, icaD, tsst, sea, seb, sec, see, seg, sei
