Bacteriophages are viruses that infect bacteria and archaea and are classified as virulent or temperate phages based on their life cycles. A temperate phage, also known as a lysogenic phage, integrates its genomes into host bacterial chromosomes as a prophage. Previous studies have indicated that temperate phages are beneficial to their susceptible bacterial hosts by introducing additional genes to bacterial chromosomes, creating a mutually beneficial relationship. This article reviewed three primary ways temperate phages contribute to the bacterial pathogenicity of foodborne pathogens, including phage-mediated virulence gene transfer, antibiotic resistance gene mobilization, and biofilm formation. This study provides insights into mechanisms of phage-bacterium interactions in the context of foodborne pathogens and provokes new considerations for further research to avoid the potential of phage-mediated harmful gene transfer in agricultural environments.
噬菌体是感染细菌和古细菌的病毒,根据其生命周期可分为烈性噬菌体或温和噬菌体。温和噬菌体,也称为溶原性噬菌体,将其基因组作为原噬菌体整合到宿主细菌染色体中。先前的研究表明,温和噬菌体通过将额外的基因引入细菌染色体,与易感细菌宿主建立互利关系,从而对宿主有益。本文综述了温和噬菌体促成食源性病原体细菌致病性的三种主要方式,包括噬菌体介导的毒力基因转移、抗生素抗性基因移动和生物膜形成。本研究深入探讨了食源性病原体背景下噬菌体与细菌相互作用的机制,并引发了新的思考,以便进一步研究,避免农业环境中噬菌体介导的有害基因转移的可能性。
