Phylogenetic trees of hla gene (a) and concatenated sequences of MLST alleles (b) in Staphylococcus aureus isolates. The percentage of the trees in which the associated hla sequence clustered together is shown next to the branches. The tree is drawn to scale, with branch lengths measured in number of substitutions per site. Evolutionary analyses were conducted in MEGA6. Note: BJ = Beijing; NX = Ningxia; SD = Shandong; HB = Hebei; LN = Liaoning; HN = Henan; GD = Guangdong; IM = Inner Mongolia; HJ = Heilongjiang. The number after regions refers to the corresponding hla type
