S.pyogenes is very sensitive to penicillin and that is the drug of choice.
I have not read of any case where a resistant organism has been found but
you might want to switch to erythromycin anyway. I don't think it is safe to
say that S. pyogenes isn't able to develope resistance, just look at S. faecalis.
