Morganella morganii: A Rare Cause of Early-Onset Neonatal Sepsis

Morganella morganii is an opportunistic Gram-negative bacillus commonly found in the human gastrointestinal tract and the environment. In adults, it is often associated with nosocomial infections, primarily surgical wound infections, urinary tract infections, and hepatobiliary infections. It is a rare cause of early-onset neonatal sepsis, with fewer than 15 reported cases in the literature. The authors aim to present a case of a low birth weight preterm born at 28 weeks' gestation, who developed early-onset neonatal sepsis due to M. morganii. We successfully treated the infection using a combination of third-generation cephalosporin and aminoglycoside, and in this report, we explain the rationale behind employing this antibiotic therapy.
