This study reports a case of Serratia marcescens cellulitis following a snakebite in a 50-year-old woman. The bite was on the dorsum of the right hand with symptoms of envenomation. She developed swelling and cellulitis with tissue necrosis. Wound debridement was performed.  Pus and tissue biopsy cultures yielded Serratia marcescens sensitive to fluoroquinolones, aminoglycosides, third-generation cephalosporins and carbapenems. The patient responded to anti-snake venom (ASV) therapy, ciprofloxacin, local wound management and recovered uneventfully.
