Corynebacterium striatus Keratitis.Heidemann, David G. M.D.; Dunn, Steven P. M.D.; Diskin, Jeffrey A. M.D.; Aiken, Timothy B. M.D.Cornea: January 1991 CASE REPORTS: PDF Only Abstract Abstract : We report a case of diphtheroid keratitis that occurred in a compromised cornea. Corneal cultures yielded heavy growth of Corynebacterium striatus on blood and chocolate agar. The infection responded slowly to treatment with topical fortified cefazolin and fortified tobramycin. This case demonstrates that diphtheroids are capable of causing ocular infections and should not routinely be dismissed as contaminants or commensals. (C) Lippincott-Raven Publishers.
