Developing his theme of bacteriocins in the food industry, Yi Xu looks in to their applications in food safety.

抗生素抗药性已成为21世纪最严峻的公共卫生挑战之一。随着细菌的快速进化,常规抗生素的有效性正在减弱,这导致即使是最普通的感染也可能变得致命。这一现象已引起全球范围内的关注和行动紧急性。 了解抗生素抗药性 Antimicrobial resistance (who.int) 抗生素抗药性是指细菌对抗生素的改变,从而使抗生素变得无效。这种抗药性的细菌可能感染人类和动物,由它们引起的感染比非抗药性细菌引起的感染更难治疗。随着时间的推移,这种抗药性可以传播给其他细菌,形成一个更大的抗药性细菌群体。 抗药性机制 An overview of the antimicrobial resistance mechanisms of bacteria – PMC (nih.gov) 抗药性的形成通常是抗生素滥用和过度使用的直接后果。这包括在健康动物中大量使用抗生素以及为病毒感染(抗生素对此无效)开抗生素处方。每当人类使用抗生素时,敏感的细菌会被杀死,但可能会留下耐药的细菌繁殖和增加。反复和不当使用抗生素是导致细菌耐药性增加的主要原因之一。此外,环境中的抗生素残留也促使细菌进化出抗药性。...
