Clostridium tetani
In general, the treatment of clostridial infection is high-dose penicillin G, to which the organism has remained susceptible. "Clostridium welchii" and "Clostridium tetani" respond to sulfonamides. Clostridia are also susceptible to tetracyclines, carbapenems (imipenem), metronidazole, vancomycin, and chloramphenicol.
