PURPOSE: To report a case of Shewannela putrefaciens endophthalmitis after penetrating keratoplasty. METHODS: Case report. Vitreous of the recipient and the preservative medium of donor cornea were cultured. RESULTS: Vitreous of the recipient eye and the donor eye corneal preservative medium both grew S putrefaciens. The patient failed to respond to intravitreal, topical, and systemic amikacin and cefotaxime. Vision was lost rapidly. Evisceration was performed. CONCLUSION: Shewannela putrefaciens should be considered as a potential pathogen contaminating donor cornea. Shewannela putrefaciens endophthalmitis is devastating and responds poorly to medical treatment.
