We report the case of a pediatric patient with a Salmonella enterica serotype Infantis infection. Detailed microbiological investigation revealed that this isolate carries four β-lactamase genes (bla variant, bla, bla,and bla) conferring resistance to all ß-lactams but imipenem. This is the first report of a Salmonella isolate with CTX-M and AmpC enzymes on the American continent, the first report of bla in Salmonella serotype Infantis, and the first report of bla in the genus Salmonella.
