Providencia rettgeri is a member of Enterobacteriacea that is known to cause urinary tract infection (UTI), septicemia, and wound infections, especially in immunocompromised patients and in those with indwelling urinary catheters. It is an uncommon cause of UTI and sepsis but should be suspected in patients with predisposing factors. The condition has high mortalty and warrants early recognition and treatment. We present here a case of UTI with sepsis by Providencia rettgeri in a young female during post partum period. She had recently delivered a male baby and was catheterized for 10 days. Patient received intravenous antibiotis and recovered completely.
