摘　　要：Leclercia adecarboxylata is a Gram-negative bacterium belonging to the Enterobacteriaceae family.To our knowledge,this is the first report of a carbapenem-resistant L.adecarboxylata strain isolated from a healthy newborn.The L.adecarboxylata strain isolated in this study carried four plasmids that may serve as reservoirs for antibiotic resistance genes.Plasmids 2 and 4 did not harbor any antimicrobial resistance genes.Plasmid 3 is a novel plasmid containing three resistance genes.The bla IMP gene harbored in the strain was most similar to bla IMP-79 at the nucleotide level,with a similarity of 99.4%(737/741).This case highlights the importance of considering L.adecarboxylata as a potential cause of infections in children.
