Pathogen variation

After a Bachelor degree in Biotechnology at the University of Bologna, in 2015 I graduated with a Master degree in Molecular and Industrial Biotechnology from the same University.

During the Master, I completed an Erasmus placement internship at the Institute for Bioengineering of Catalonia (IBEC), in Barcelona (Spain), within the “Microbial biotechnology and host-pathogen interaction” group led by Dr Antonio Juárez Giménez, where I investigated plasmid-encoded antibiotic resistance in Salmonella.

In October 2015 I started my PhD at the Quadram Institute Bioscience with the project “A risk assessment of pandemic monophasic Salmonella Typhimurium (1,4,[5],12:i:-), a recently emergent serovar in the pork chain” in collaboration with the Teagasc Food Research Centre in Dublin (Ireland), through whom the research is funded.

The aim of the study is to investigate an epidemic variant of Salmonella enterica serovar Typhimurium through phenotypic and phylogenomic characterisation of isolates from the Irish pork chain. This variant has rapidly established itself as dominant in Europe, where it has been responsible for several major outbreaks. Pigs constitute the main reservoir of the pathogen whose meat products represent an important source of infection.
