In the last years, Salmonella enterica serovar Heidelberg (SH) has become one of most frequently recovered serovars from broiler farms in Argentina. Resistance to various antimicrobial agents, including extended-spectrum cephalosporins (ESC) has been found among SH isolates thus demanding a more profound study of the mechanisms involved in order to contribute to the rational use of antimicrobials to treat salmonellosis in poultry. The aim of this study was to determinate the resistance to ESC on SH recovered from poultry farms located in two different geographical regions from Argentina.
