Phylogenetic analysis and temporal distribution of S. Corvallis strains. a Maximum likelihood tree of 388 ST1541 S. Corvallis strains in this study and those deposited in NCBI database. The ring from inner to outer indicates year of collection; the source; country of isolation; PMQR genes. Clades color and branch color indicate different sequence lineages in Bayesian hierarchical clustering analysis. The scale bar indicates nucleotide substitutions per site. b Temporal distribution of PMQR genes and sequenced S. Corvallis isolates by region
