We report the dissemination of a conjugative IncI1 plasmid carrying blaCTX-M-1, conferring resistance to extended-spectrum cephalosporins, in Salmonella enterica isolates from poultry and humans in France from 2003 to 2008. By IncI1 plasmid subtyping, this plasmid was shown to be genetically related to that found in Escherichia coli isolates from healthy poultry in France.
