This thesis highlights the intricate relationship between antimicrobial resistance, pathogenic bacteria and protective cultures, emphasising the need for comprehensive strategies to address emerging food safety and public health challenges. Antimicrobial resistance is a significant global threat, fuelled by the widespread use of antibiotics in various sectors, including human medicine, agriculture and aquaculture. The emergence of multi-resistant strains and the transfer of resistance mechanisms between microorganisms in the environment, food and the human gut are growing concerns. This thesis explores the dynamics of antimicrobial resistance, focusing on its origins, mechanisms of transmission to microorganisms.The pathogenic bacteria, Listeria monocytogenes and Escherichia coli, contribute significantly to food-borne diseases in humans. Transmission occurs mainly through the ingestion of contaminated food. In addition, zoonotic agents and environmental pathogens can be transmitted between animals and humans, underlining the interconnectedness of the food chain and the need for a holistic approach to food safety. Integrating protective cultures into food production represents a promising avenue to improve microbial safety and minimise the risks associated with antimicrobial resistance.
Questa tesi evidenzia l'intricata relazione tra resistenza antimicrobica, batteri patogeni e colture protettive, sottolineando la necessità di strategie globali per affrontare le sfide emergenti in materia di sicurezza alimentare e salute pubblica. La resistenza antimicrobica è una minaccia globale significativa, alimentata dall'uso diffuso di antibiotici in vari settori, tra cui la medicina umana, l'agricoltura e l'acquacoltura. L'emergere di ceppi multiresistenti e il trasferimento di meccanismi di resistenza tra microrganismi nell'ambiente, negli alimenti e nell'intestino umano sono preoccupazioni crescenti. Questa tesi esplora le dinamiche della resistenza antimicrobica, concentrandosi sulle sue origini e sui meccanismi di trasmissione ai microrganismi.I batteri patogeni, Listeria monocytogenes ed Escherichia coli, contribuiscono in modo significativo alle malattie di origine alimentare nell'uomo. La trasmissione avviene principalmente attraverso l'ingestione di alimenti contaminati. Inoltre, agenti zoonotici e patogeni ambientali possono essere trasmessi tra animali ed esseri umani, sottolineando l'interconnessione della catena alimentare e la necessità di un approccio olistico alla sicurezza alimentare. L'integrazione di colture protettive nella produzione alimentare rappresenta una strada promettente per migliorare la sicurezza microbica e minimizzare i rischi associati alla resistenza antimicrobica.
