Only two ESC-resistant isolates were detected, giving a low percentage of strains resistant to ESC (0.2%). One multidrug-resistant (MDR) isolate of the Virchow serotype produced a CTXM-3 extended-spectrum\n                    <jats:italic toggle=\"yes\">\u03b2<\/jats:italic>\n                    -lactamase (ESBL).

The second ESC-resistant isolate belonged to serotype Newport, was also MDR and produced a CMY-2 cephamycinase. This CMY-2\u2013producing isolate (also called Newport MDR-AmpC) possessed a class 1 integron with a 1-kb gene cassette including a new variant of the\n                    <jats:italic toggle=\"yes\">aadA<\/jats:italic>\n                    gene,\n                    <jats:italic toggle=\"yes\">aadA24<\/jats:italic>\n                    .
