Unusual Salmonella enterica serotype Typhimurium isolate producing CMY-7, SHV-9 and OXA-30 beta-lactamases.
Beta-lactam resistance in Salmonella isolates is increasing. This paper describes the combination of three different beta-lactamases, OXA-30, SHV-9 and CMY-7, expressed by an isolate of Salmonella enterica serotype Typhimurium. This is the first report of an isolate of Salmonella having both an extended-spectrum beta-lactamase and an AmpC beta-lactamase.
