Morganella morganii Bacteremia in an Immunocompetent 13-Year-Old Male: A Rare Pediatric Case.

Morganella morganii is a gram-negative bacillus with intrinsic resistance to many β-lactam antibiotics, including penicillins and first-/second-generation cephalosporins. It is frequently associated with urinary tract, wound, and respiratory infections, and can develop into bacteremia in older adults due to age-related comorbidities and immunosenescence, but this has rarely been described in children. In this report, we present the case of a 13-year-old male with a urinary tract infection complicated by M. morganii bacteremia, who was successfully treated with antibiotics. To our knowledge, this is one of the few documented cases of M. morganii bacteremia in an immunocompetent pediatric patient.
