• In a case of metastatic Gram-negative endophthalmitis caused by Serratia marcescens, the bacterial isolate was resistant to gentamicin sulfate and tobramycin but sensitive to amikacin sulfate, a new semisynthetic aminoglycoside approved for systemic use. The importance of antibiotic-resistant S marcescens as a systemic and ocular pathogen is reviewed.
