- P-262 - Extended-Spectrum Cephalosporin-Resistant CMY-2-Producing Salmonella Heidelberg and S. Minnesota in Poultry Meat Imported into the European UnionPublication . Campos, Joana; Mourão, Joana; Silveira, Leonor; Saraiva, Margarida; Belo Correia, Cristina; Maçãs, Ana Paula; Peixe, Luísa; Antunes, PatríciaExtended-spectrum cephalosporin-resistant (ESC-R) Salmonella has been described at low level in EU, including in Portugal. Nevertheless, the increasing poultry meat trade involving countries with different animal production practices could be an important source of epidemic clones carrying ESC-R genes. In this study phenotypic and genotypic characterization of resistance to ESC was carried out, as well as the clonal relatedness analysis of Salmonella obtained from poultry meat samples imported into Portugal in the scope of official border control between 2014 and 2015.
