title: [Morganella morganii endophthalmitis after vitrectomy: case report and review of the literature].
abstract: BACKGROUND
  Postoperative bacterial endophthalmitis are caused in 80 % of the cases by the patient's own flora. Most of the time, bacterial agents are Gram-positive ((2/3) of cases) and more rarely Gram-negative ((1/3) of cases). Usually, Pseudomonas sp, Proteus sp or Klebsiella sp are isolated, but very rarely Morganella morganii.
  
  
  METHODS
  We describe a case of a Morganella morganii endophthalmitis which occurred after a vitrectomy.
  
  
  RESULTS
  Bacterial examinations disclosed the presence of Morganella morganii in the vitreous. An aggressive treatment (intravitreous [ceftazidim, vancomycin], topical [gentamycin, chloramphenicol] and intravenous [imipenem, ofloxacin] antibiotics) was introduced. In spite of this treatment, the outcome was not favorable.
  
  
  CONCLUSIONS
  Post-vitrectomy endophthalmitis is very rare and the isolation of a Gram-negative bacteria, in this case Morganella morganii, is infrequent. The outcome of these infections is often poor despite the introduction of a rapid, specific and aggressive treatment.
