A Conjugative IncI1 Plasmid Carrying erm(B) and blaCTX-M-104 That Mediates Resistance to Azithromycin and Cephalosporins
ABSTRACT In this study, an IncI1 plasmid encoding resistance to both cefotaxime and azithromycin was recovered from a clinical Klebsiella pneumoniae strain.The azithromycin resistance was confirmed to be mediated by the erm(B) gene.This plasmid could be readily conjugated to strains of Escherichia coli and Salmonella, promoting rapid dissemination
