    • Characterization of Escherichia coli carrying mcr-1-plasmids recovered from food animals from Argentina 

      Dominguez, Johana Elizabeth; Faccone, Diego; Tijet, Nathalie; Gomez, Sonia; Corso, Alejandra; Fernandez Miyakawa, Mariano Enrique; Melano, Roberto G. (Frontiers Media, 2019-03)
      In this study, we found mcr-1.1 and mcr-1.5 genes carried by IncI2 plasmids in a subset of Escherichia coli isolates recovered from commercial broiler farms in Argentina. The comparative analysis of the sequences of these ...

    • Molecular characterization and antimicrobial resistance profiles of Salmonella Heidelberg isolates from poultry 

      Dominguez, Johanna Elizabeth; Viñas, María Rosa; Herrera, Mariana; Moroni, Mirian; Gutkind, Gabriel Omar; Mercado, Elsa Cristina; Di Conza, José Alejandro; Chacana, Pablo (Wiley, 2021-02)
      In the last 10 years, Salmonella Heidelberg has been extensively isolated from poultry in several countries. In this context, molecular characterization is essential to understand whether the strains have entered the farms ...

    • Rats as sources of multidrug-resistant Enterobacteriaceae in animal production environments 

      Dominguez, Johanna Elizabeth; Lovera, Rosario; Sánchez, Juliana; Redondo, Leandro Martin; Chacana, Pablo; Cavia, Regino; Fernandez Miyakawa, Mariano Enrique (Wiley, 2023-07)
      Rattus norvegicus and Rattus rattus are commensal pest rodents, considered reservoirs and vectors of zoonotic pathogens. In livestock farms, the wide use of antimicrobials and their release into the environment lead to ...

    • Simultaneous carriage of mcr-1 and other antimicrobial resistance determinants in Escherichia coli from poultry 

      Dominguez, Johanna Elizabeth; Redondo, Leandro Martín; Figueroa Espinosa, Roque A.; Cejas, Daniela; Gutkind, Gabriel Omar; Chacana, Pablo; Di Conza, José Alejandro; Fernandez Miyakawa, Mariano Enrique (Frontiers Media, 2018-07)
      The use of antimicrobial growth promoters (AGPs) in sub-therapeutic doses for long periods promotes the selection of resistant microorganisms and the subsequent risk of spreading this resistance to the human population and ...
