As far as antimicrobial resistance, S.
pyogenes has remained highly susceptible to almost all classes of antibiotics [Table 1] (Bourbeau & Campos, 1982; Kayser, 1994; Chin, Gu, Yu, Zhang, & Neu, 1991; Cohen, et al., 1991; Bouanchaud, 1997; Blondeau, Church, Yaschuk, & Bjarnason, 1999)..

Medication Summary To date, S pyogenes has remained universally susceptible to penicillin. Therefore, penicillin remains the first-line drug of choice for pharyngeal infections, as well as for complicated or invasive infections.
What can kill Streptococcus pyogenes?
pyogenes is solely mediated by hydrogen peroxide. Killing required live streptococci; the killing capacity depends on the amount of hydrogen peroxide produced, and killing can be inhibited by catalase.
What infections does Streptococcus pyogenes cause?
Life-threatening infections caused by Streptococcus pyogenes (group A streptococcus) include scarlet fever, bacteremia, pneumonia, necrotizing fasciitis, myonecrosis and Streptococcal Toxic Shock Syndrome (StrepTSS).
