Abstract Details

Purpose:

Enterococci are Gram-positive facultative anaerobes and have been documented as a cause of infective endocarditis, burn wound sepsis, meningitis, urinary tract infections and nosocomial infections, Morganella Morganii are Gram-negative bacilli belonging to the family Enterobacteriaceae, which is a pathogen of urinary tract infections. both causing ocular infection is extremely rare, The aim of this report is to create awareness among clinicians and microbiologists that Enterococci and Morganella morganii, although uncommon, could cause complicated infections of the eye; a high index of suspicion is required.

Setting:

An 85 year old female k/c/o HTN, DM and RF.She had gastroenteritis, pain and redness in right (blind) eye with corneal decompensation, scarring, right-eye corneal ulcer with hypopyon. Corneal scrapings sent for culture report revealed growth of Morganella Morganii and Enterococci. Corneal ulcer was successfully treated with topical/oral antibiotics.

Methods:

She was diagnosed as right eye keratitis (corneal ulcer), Eye swab and corneal scrapping was sent for culture and sensitivity. An empirical treatment including topical Gatifloxacin eye drops every hour with erythromycin ointment every six hours was initiated, The culture revealed moderate growth of Morganella morganii and Enterococci, then topical antibiotics changed according to the culture and sensitivity.

Results:

Corneal ulcer was successfully treated with topical and oral antibiotics based on culture and sensitivity guidance.

Conclusions:

Ophthalmologists are encouraged to be aware of the potential risk of complicated mixed microbial keratitis from the environment, particularly in communities with high level of antimicrobial resistant reservoirs. Enterococci and Morganella morganii although uncommon cause of complicated infection, a high index of suspicion and coordination between clinicians and microbiologists is required in order to achieve a better outcome.
