Phylogenic trees of the MRSA strains by pulsed-field gel electrophoresis and SNPs analysis. (a) PFGE and similarity analysis of the 10 MRSA strains. Saitama2 was used as the reference strain. Band patterns of Saitama4, − 5, − 8, − 10, − 13 and − 14 were visibly indistinguishable from that of Saitama2, and the dendrogram showed high identity with Saitama2 (PFGE type A1, 2 and 3). Saitama11, − 1 and − 9 showed different band patterns from Saitama2, however, the band differences were within three bands (PFGE type B1, 2 and 3). Saitama9 demonstrated maximum similarity to Saitama2 (86% identity). These results confirmed all 10 strains had genetic relatedness with each other. MRSA, methicillin-resistant Staphylococcus aureus; PFGE, pulsed-field gel electrophoresis; SNPs, single nucleotide polymorphisms. (b) Phylogenic tree of the 10 MRSA strains inferred with SNPs analysis. Saitama2 was used as the reference strain, and the number of SNPs ranged from 35 to 119. MRSA, methicillin-resistant Staphylococcus aureus; PFGE, pulsed-field gel electrophoresis; SNPs, single nucleotide polymorphisms
