Main research interests

  • Food Microbiology; Food Safety; Public Heath; Molecular Epidemiology.
  • Epidemiological and molecular studies of non-typhoid Salmonella and other foodborne pathogens from different ecological niches (human, food products, animal and environmental).
  • Understand the main factors influencing the emergence and persistence of particular clones and genetic elements associated with horizontal transmission of antibiotic and biocide resistance
  • Characterization of genes and mobile genetic elements involved in resistance to antibiotics and other molecules with antimicrobial activity and/or virulence
  • Understand the role of community ecological niches in the selection and spread of bacteria and / or genes with human clinical interest
  • New methods for detection, identification and typing of foodborne pathogens
