In vivo acquisition of high-level resistance to imipenem in Escherichia coli

J Clin Microbiol. 2004 Aug;42(8):3831-3. doi: 10.1128/JCM.42.8.3831-3833.2004.

Abstract

Four clonally related Escherichia coli strains were isolated successively from bile duct of a girl suffering from sclerosing cholangitis. One of them, selected after an imipenem-containing regimen, was resistant to carbapenems and to broad-spectrum cephalosporins due to a plasmid-mediated cephalosporinase, CMY-2, and the lack of outer membrane proteins OmpF and OmpC.
