Sporadic sore throat in adults from whom hemolytic streptococci were isolated was found to be due to S. epidemicus in approximately 10 per cent of the patients. Up to this time S. epidemicus has been identified only in connection with milk-borne epidemics of septic sore throat. Our investigations1 have shown sore throat in its natural
