Differences in PRISM scores between different MLST-type isolates and different Staphylococcus protein A (SPA)-type isolates. Differences in PRISM score between different MLST-type and SPA-type groups are not statistically significant (one-way ANOVA test). Note: ST59 only had two MSSA strains. ST25, ST7, and ST2155 only comprised MSSA strains. ST188 only had one MRSA strain. ST88 had five MRSA and 15 MSSA strains. t437 only had three MSSA strains, whereas t441 only comprised MRSA strains. t091 and t189/t078 only comprised MSSA strains.
