We present 2 cases of urinary tract infections from rural areas of West Bengal, caused by Serratia mercescens. Though Serratia marcescens is an important nosocomial pathogen, it’s emergence as a community acquired uropathogen has not been reported frequently. Further, both the cases were immunocompetent & of extreme age groups- contradicting the idea of its age & immune status dependent virulence. In both of our cases, the isolated Serratia marcescens strains were beta lactamase producing, conferring resistance to broad spectrum beta lactam antibiotics. So in our cases treatment was modified to ceftazidime & patients’ conditions improved.
