An isolate of Salmonella enteritidis was found to produce a plasmid-encoded beta-lactamase (DHA-1) that conferred resistance to extended-spectrum cephalosporins and cephamycins. The substrate and inhibition profiles of this enzyme resemble a class C beta-lactamase. This is the first report of a plasmid-mediated cephalosporinase of this class in the Salmonella genus.
一株肠炎沙门氏菌被发现可产生一种质粒编码的β-内酰胺酶(DHA-1),该酶可使细菌对超广谱头孢菌素和头霉素产生耐药性。这种酶的底物和抑制谱类似于C类β-内酰胺酶。这是沙门氏菌属中此类质粒介导的头孢菌素酶的首次报道。
