      Costa, Magdalena; Sucari, Adriana; Epszteyn, Sergio; Oteiza, Juan Martín; Gentiluomo, Jimena; Melamed, Celia; Figueroa, Yamila; Mingorance, Santiago Emmanuel; Grisaro, Agustina; Spioussas, Silvia; Buffoni Almeida, Mariana; Caruso, Mailen; Pontoni, Andrés; Signorini, Marcelo; Leotta, Gerardo Anibal (Elsevier, 2019-12)
      Shiga toxin-producing Escherichia coli (STEC) are important pathogens transmitted by food that may cause severe illness in human beings. Thus, systems for STEC detection in food should have increasingly higher sensitivity ...

      Costa, Magdalena; Pracca, Gabriela; Sucari, Adriana; Galli, Lucía; Ibargoyen, José; Gentiluomo, Jimena; Brusa, Victoria; Martinez Zugazua, Matías; Figueroa, Yamila; Londero, Alejandra; Rogé, Ariel Diego; Silva, Hernán; Ploeg, Claudia A. Van Der; Signorini, Marcelo; Oteiza, Juan Martín; Leotta, Gerardo Anibal (Elsevier, 2020-03)
      The slaughter process plays an important role in animal welfare, meat quality, safety and public health through the meat production chain. In this study, we performed a three-stage evaluation: I) comprehensive evaluation, ...
    • Evaluation of decontamination efficacy of commonly used antimicrobial interventions for beef carcasses against Shiga toxin-producing Escherichia coli 

      Signorini, Marcelo; Costa, Magdalena; Teitelbaum, David; Restovich, Viviana; Brasesco, Hebe; García, Diego; Superno, Valeria; Petroli, Sandra; Bruzzone, Mariana; Arduini, Victor; Vanzini, Mónica; Sucari, Adriana; Suberbie, Germán; Turina, Maricel; Rodriguez, Hector Ricardo; Leotta, Gerardo A. (2018-08)
      In Argentina, Shiga toxin producing Escherichia coli (STEC) serogroups O157, O26, O103, O111, O145 and O121 are adulterant in ground beef. In other countries, the zero-tolerance approach to all STEC is implemented for ...
    • Isolation and characterization of non-O157 Shiga toxin-producing Escherichia coli from beef carcasses, cuts and trimmings of abattoirs in Argentina 

      Brusa, Victoria; Restovich, Viviana; Galli, Lucía; Teitelbaum, David; Signorini, Marcelo; Brasesco, Hebe; Londero, Alejandra; García, Diego; Padola, Nora Lía; Superno, Valeria; Sanz, Marcelo; Petroli, Sandra; Costa, Magdalena; Bruzzone, Mariana; Sucari, Adriana; Ferreghini, Marcela; Linares, Luciano; Suberbie, Germán; Rodriguez, Hector Ricardo; Leotta, Gerardo Anibal (2017-08-22)
      Several foods contaminated with Shiga toxin-producing Escherichia coli (STEC) are associated with human diseases. Some countries have established microbiological criteria for non-O157 STEC, thus, the absence of serogroups ...
    • Quantitative risk assessment of haemolytic uremic syndrome associated with beef consumption in Argentina 

      Brusa, Victoria; Costa, Magdalena; Padola, Nora Lía; Etcheverría, Analía Inés; Sampedro, Fernando; Fernandez, Pablo S.; Leotta, Gerardo Anibal; Signorini Porchiett, Marcelo Lisandro (Plos One, 2020-11)
      We developed a quantitative microbiological risk assessment (QMRA) of haemolytic uremic syndrome (HUS) associated with Shiga toxin-producing Escherichia coli (STEC)-contaminated beef (intact beef cuts, ground beef and ...
