Despite the availability of antimicrobial drugs to treat CDI, such as vancomycin, metronidazole, and fidaxomicin, recurrence of infection remains a significant clinical challenge. The use of live commensal microorganisms, or probiotics, is one of the most investigated non-antibiotic therapeutic options to balance gastrointestinal (GI) microbiota and subsequently tackle dysbiosis. In this review, we will discuss major commensal probiotic strains that have the potential to prevent and/or treat CDI and its recurrence, reassess the efficacy of probiotics supplementation as a CDI intervention, delve into lessons learned from probiotic modulation of the immune system, explore avenues like genome-scale metabolic network reconstructions, genome sequencing, and multi-omics to identify novel strains and understand their functionality, and discuss the current regulatory framework, challenges, and future directions.Pages 414-43421 page(s)application/pdfenIn CopyrightProbioticsC. difficileinhibitionvirulenceimmunomodulatorygenomic explorationdiscovery informaticsmetabolomicsmulti-omicsregulatory requirementsHumansClostridium InfectionsVancomycinAnti-Bacterial AgentsProbioticsClostridioides difficileClostridioidesProbiotics: insights and new opportunities for <i>Clostridioides difficile</i> interventionArticle - RefereedCritical Reviews in Microbiologyhttps://doi.org/10.1080/1040841X.2022.2072705493Seleem, Mohamed [0000-0003-0939-0458]355746021549-7828
