Monitoring AMR in Campylobacter jejuni from Italy in the last 10 years (2011–2021): Microbiological and WGS data risk assessment

Campylobacter jejuni is considered as the main pathogen in human food‐borne outbreaks worldwide. Over the past years, several studies have reported antimicrobial resistance (AMR) in C. jejuni strains. In Europe, the official monitoring of AMR comprises the testing of Campylobacter spp. from food‐producing animals because this microorganism is responsible for human infections and usually predominant in poultry. Food‐producing animals are considered to be a major source of campylobacteriosis through contamination of food products. Concerns are growing due to the current classification of C. jejuni by the WHO as a ‘high priority pathogen’ due to the emergence of resistance to multiple drugs such as those belonging to the fluoroquinolones, macrolides and other classes, which limits the treatment alternatives.
