Professional profile

Antonia Anna Lettini graduated in Biological Sciences from the University of Modena and Reggio Emilia (Italy) and was awarded her postgraduate diploma in Biotechnological Applications at the University of Bari (Italy). She worked for some years in the framework of research projects in the biomedical sector, specifically in molecular oncology. To date, as part of the Department of Food Safety at the IZSVe, she works at SCS1, Risk Analysis and Surveillance Systems in Public Health – Biofood Laboratory.

Her research activities are focused on: development of typing and sub-typing methods to characterize bacterial strains, especially Salmonella spp. responsible for foodborne outbreaks; application of phenotypic and genotypic methods to characterize antimicrobial resistance profiles of different microorganisms.

Her diagnostic and research activities at the Biofood laboratory at IZSVe (Legnaro) involve: typing and sub-typing methods for Salmonella isolates from food and animal samples; identification of animal species from human food by molecular methods; characterization of genetically modified organisms in human and animal food products; development of molecular methods to characterize antimicrobial resistance profiles of Salmonella strains.

She is involved in activities to set up and coordinate the IZSVe Biofood laboratory.

Member of the Working Group of the network of Italian Istituti Zooprofilattici, established to harmonize the procedures regulating the development and validation of molecular methods applied to food safety control (IZSPLV, IZSLER, IZSVe).
