title: Postkeratoplasty endophthalmitis by Alcaligenes faecalis: a case report.
abstract: OBJECTIVE
  To describe a postkeratoplasty endophthalmitis owing to Alcaligenes faecalis that resolved with medical management.
  
  
  METHODS
  Case report and review of literature.
  
  
  RESULTS
  To best of our knowledge, postkeratoplasty endophthalmitis caused by A. faecalis has not been reported in literature. The source of infection was found to be the donor tissue. The organism isolated was resistant to gentamicin, which was the only antibiotic present in the storage medium (McCarey and Kaufman medium). The patient was treated aggressively with topical, systemic and intravitreal antibiotics. The endophthalmitis resolved completely within two weeks.
  
  
  CONCLUSIONS
  A. faecalis is a gram negative, non-spore forming rod that can cause endophthalmitis if donor tissue is contaminated with the organism. Clinical suspicion, review of bacterial culture and sensitivity report from donor tissue, anterior chamber and vitreous taps, along with early therapy with appropriate antibiotics can lead to resolution of infection.
