Real-time qPCR analysis using bacterial 16S rRNA gene quantified the abundance of six key bacterial groups (Firmicutes, <em>Lactobacillus</em> spp., <em>Bifidobacterium</em> spp., <em>Fusobacterium</em> spp., <em>Bacteroides fragilis</em>, and <em>Faecalibacterium prausnitzii</em>) in faecal samples from 30 IBD patients (13 Crohn's disease, 17 ulcerative colitis) and 30 healthy controls. A correlation matrix was employed to assess relationships between these bacteria.</div></div><div><h3>Results</h3><div>Real-time qPCR revealed significant differences (<em>p</em>-value &lt;0.05) in the abundance of several bacterial groups between IBD patients and healthy controls. Firmicutes, Fusobacterium spp., and <em>B. fragilis</em> were significantly more abundant (<em>p</em>-value &lt;0.05) in IBD patients compared to controls. Conversely, <em>Lactobacillus</em> spp. and <em>F. prausnitzii</em> were both significantly less abundant (<em>p</em>-value &lt;0.05) in IBD patients. While some bacterial groups exhibited trends toward higher abundance in either CD or UC patients, these differences were not statistically significant (<em>p</em>-value &gt;0.111). The correlation matrix analysis revealed specific co-occurrence patterns: <em>Bacteroides</em> showed a strong negative correlation with <em>Prevotella</em>, more abundant in healthy controls, suggesting a shift in dominance in IBD patients. <em>Lactobacillus spp.</em> and <em>F. prausnitzii</em> exhibited a positive correlation in healthy individuals, indicating their potential cooperative role in maintaining gut homeostasis.</div></div><div><h3>Conclusion</h3><div>This study identified significant alterations in gut microbiota composition in adult IBD patients compared to healthy controls, with notable differences in the abundance of specific bacterial groups. These findings suggest that gut microbiota dysbiosis may play a critical role in IBD pathogenesis. The identification of specific bacterial imbalances provides a foundation for developing microbiota-based therapies, such as probiotics, prebiotics, and fecal microbiota transplantation, as potential interventions for restoring microbial balance and mitigating disease progression. Further research is needed to translate these insights into targeted therapeutic strategies and to explore their effectiveness in clinical settings.</div></div>","PeriodicalId":38074,"journal":{"name":"New Microbes and New Infections","volume":"64 ","pages":"Article 101567"},"PeriodicalIF":2.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
