[Morganella morganii and early-onset neonatal infection]

Abstract

Morganella morganii is an opportunistic gram-negative bacterium, resistant to ampicillin, and scarcely involved in early-onset neonatal sepsis.

Case report: After a premature rupture of the membranes, a pregnant patient received prophylactic amoxicillin per os. She developed chorioamnionitis. Her infant was diagnosed with early-onset sepsis. Maternal and baby's blood cultures grew M. morganii. Both the mother and the infant were successfully treated with a third-generation cephalosporin and an aminoglycoside.

Discussion: The influence of a prior antibiotherapy on the emergence of M. morganii vertical infections is discussed.
