Cluster analysis based on spa typing of 60 Staphylococcus aureus strains isolated from blood cultures. The minimum spanning tree was constructed using Bionumerics software (Applied Maths, Sint-Martens-Latem, Belgium). Genotypes determined by using accessory gene regulator (agr) polymorphism and sequence type (ST) correlated well with spa typing clustering. Methicillin susceptibility, δ-hemolysin production, toxic shock syndrome toxin (TSST), and Panton–Valentine leukocidin (PVL) toxin were denoted.
