Sumario:Extended-spectrum cephalosporins (ESC) are an important drug class for treating severe Salmonella infections. We screened the human collection from the National Antimicrobial Resistance Monitoring System 2000 for ESC resistance mechanisms. Of non-Typhi Salmonella tested, 3.2% (44/1,378) contained bla(CMY) genes. Novel findings included bla(CMY)-positive Escherichia coli O157:H7 and a bla(SHV)-positive Salmonella isolate. CMY-positive isolates showed a ceftriaxone MIC >2 µg/mL.
