Abstract
The literature from 1949 has been reviewed details of 9 other acceptable cases are abstracted. Although uncommon this disease may be important because of liability to recurrence difficulty in cure; it may follow streptococcal endocarditis or cardiac surgery. The etiologic significance of corynebacteria recovered from cases of endocarditis is difficult to establish since there is always a possibility of contamination. Diphtheroids which are discarded as contaminants or which are not isolated because they require prolonged possibly anaerobic culture might conceivably be responsible for some examples of endocarditis which are presently classified as erile.
