Dissemination of an extended-spectrum-β-lactamase blaTEM-52 gene-carrying IncI1 plasmid in various Salmonella enterica serovars isolated from poultry and humans in Belgium and France between 2001 and 2005

We report here the dissemination of a conjugative IncI1 plasmid carrying blaTEM-52 on a Tn3 transposon conferring resistance to extended-spectrum cephalosporins in Salmonella enterica serovar Agona, Derby, Infantis, Paratyphi B dT+, and Typhimurium isolates from poultry and humans in Belgium and France from 2001 to 2005. The most prevalent serovar spreading this resistance was serovar Infantis. Copyright © 2007, American Society for Microbiology. All Rights Reserved
