title: Postkeratoplasty Keratitis Caused by Abiotrophia defectiva: An Unusual Cause of Graft Infection.
abstract: Abiotrophia defectiva is a nutritional variant of Streptococci. We describe a case of microbial keratitis due to A. defectiva in a patient who had undergone penetrating keratoplasty and was on corticosteroid therapy for recent graft rejection. Isolation of this organism confirmed this to be an opportunistic infection.
