Endophthalmitis caused by Moraxella nonliquefaciens

We report the first case of endophthalmitis caused by Moraxella nonliquefaciens. Most likely, entry followed minor trauma from a contact lens, with the marked invasiveness of the organism resulting from the patient's immunocompromised state. This case, in addition, serves to illustrate the advantage of genetic transformation assay to differentiate the species of this group of organisms.
