a

Musser laboratory GAS strain number.

b

Strains from Utah were collected during ARF outbreaks.

c

Clinical diagnosis is provided when known. LC, Lancefield collection; RF, rheumatic fever; NCTC, National Collection of Type Cultures; TSLS, toxic shock-like syndrome.

d

PCR was used to detect speL and speM. The genes were subsequently sequenced.
