"C. aquaticum" is not a validly published name - it has been associated with UTI, endocarditis, meningitis and CAPD peritonitis - reported susceptible to ampicillin, chloramphenicol and gentamicin - has been confused with Microbacterium (as Aureobacterium) -
C. diphtheriae is the agent of diphtheria and cutaneous infection - penicillin and erythromycin are recommended therapeutic agents - toxigenic infections require treatment with antitoxin -
C. minutissimum has been associated with erythrasma, bacteraemia and endocarditis - C. mycetoides has been associated with tropical ulcer and septicaemia -
C. pseudodiphtheriticum - associated with UTI, endocarditis, lymphadenopathy, necrotising tracheitis - C. pseudotuberculosis causes pulmonary infection and lymphadenitis, is associated with sheep contact; treated with penicillin or erythromycin and lesions may require drainage or excision - C. ulcerans may cause pharyngitis or diphtheria-like illness; treated with penicillin or erythromycin; toxigneic infection requires treatment with antitoxin
