*Boldface indicates a statistically significant result.
†Does not include 48 TSS isolates that did not have sea, seb, sec, sed, or tst in isolation.
‡Three additional TSS isolates could not be classified as menstrual or nonmenstrual due to lack of clinical data
§By Fisher exact test comparing the percentage carriage of a given superantigen gene among menstrual and nonmenstrual isolates.
