In this study, virtual screening and thermal shift assays identified Baohuoside I (BI), a flavonol glycoside, as a potent inhibitor of the SaeR response regulator. BI significantly attenuated S. aureus pathogenicity without bactericidal effects, suppressing the expression of key virulence factors, such as hemolysin A (Hla) and Panton-Valentine leukocidin (PVL), while modulating immune evasion pathways. Additionally, BI disrupted biofilm formation, promoting the development of porous, less structured biofilms. Biochemical assays, including EMSA, CETSA, fluorescence quenching, and SPR, confirmed strong binding interactions between SaeR and BI. In vivo, BI demonstrated therapeutic efficacy in Galleria mellonella and rat MRSA models. These findings establish BI as a promising lead for nonbactericidal therapies to combat MRSA infections and mitigate resistance.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"45"},"PeriodicalIF":7.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11920273/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most dominant cluster of vOTUs in the cohort was related to Bacteroides phage Hanky p00', and it carried both diversity generating retroelements and genes involved in capsular polysaccharide synthesis. Paired analysis of viromes and metagenomes from the same samples revealed that most prophages within the infant gut were induced and that induction was unaffected by a range of environmental perturbers.

In this study, we identify gut microbiota-derived succinate as a driver of inflammation in ulcerative colitis (UC) by activating succinate-responsive, colitogenic helper T (Th) cells that secrete interleukin (IL)-9. We demonstrate that colitis is associated with an increase in succinate-producing gut bacteria and decrease in succinate-metabolizing gut bacteria. Similarly, UC patients exhibit elevated levels of succinate-producing gut bacteria and luminal succinate. Intestinal colonization by succinate-producing gut bacteria or increased succinate availability, exacerbates colonic inflammation by activating colitogenic Th9 cells. In contrast, intestinal colonization by succinate-metabolizing gut bacteria, blocking succinate receptor signaling with an antagonist, or neutralizing IL-9 with an anti-IL-9 antibody alleviates inflammation by reducing colitogenic Th9 cells. Our findings underscore the role of gut microbiota-derived succinate in driving colitogenic Th9 cells and suggesting its potential as a therapeutic target for treating IBD.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"44"},"PeriodicalIF":7.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11906746/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143625534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vacuolar proton pump (V-ATPase) is a vital enzyme regulating the growth and virulence of C. albicans, which is a potential target for caries prevention. However, the effect of V-ATPase on the cariogenicity of C. albicans-S. mutans biofilm remains to be explored. In this study, the detection rate of C. albicans in caries-active (group CA) (22.03%) was significantly higher than that in caries-free (group CF) children (8.00%), and the expression of V-ATPase related genes were higher in group CA. Then, the higher expressed V-ATPase coding genes VMA3, VMA4 and VMA11 in CA group were knocked out. Compared with the wild type SC5314, the mutants showed slower growth rate, inhibited hyphal growth, and defective integrity of cell wall. The biofilm biomass and extracellular polysaccharide (EPS) production of dual biofilm were significantly reduced, and the biofilm structure was impacted. Transcriptome analysis indicated that V-ATPase participated in various metabolisms and biosynthesis pathways of C. albicans, and influenced EPS metabolism of S. mutans. Finally, compared with the positive control, the caries severity, the biomass and EPS production of dental plaque were significantly reduced after deletion of VMA3, VMA4 and VMA11 in vivo. This study revealed for the first time the regulating effect of V-ATPase on the cariogenicity of C. albicans-S. mutans biofilm and its potential mechanisms. The results may provide basis for new strategies of ecological prevention and treatment of dental caries.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"41"},"PeriodicalIF":7.8,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11890576/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A detailed analysis of the intimate relationship between N. punctiforme and the isolate Agrobacterium tumefaciens Het4 using shotgun proteomics and microscopy uncovered a complex partnership characterized by competition for iron and facilitation for carbon. The prevalent extracarboxysomal localization of the carbon-fixing enzyme RubisCO suggests that a weak carbon-concentrating mechanism in N. punctiforme enforces a dependence on heterotrophic bacteria.

Here, the expression profile of c-di-GMP metabolism-related genes was analysed among 32 P. aeruginosa strains grown as aggregates in synthetic cystic fibrosis sputum. The diguanylate cyclase SiaD proved essential for auto-aggregation under in vivo-like conditions. Virtual screening predicted a high binding affinity of echinacoside towards the active site of SiaD.

This study showed that periodontitis patients exhibited elevated tryptophan metabolism and salivary pathogen abundance. Tryptophanase gene-deficiency altered proteome and metabolome of P. gingivalis, inhibited P. gingivalis virulent factors expression, biofilm growth, hemin utilization, cell adhesion/invasion and pro-inflammation ability.

In periodontitis mice, this pathway of P. gingivalis aggravated alveolar bone loss and gingival tissue destruction, causing oral and gut microbiota dysbiosis.
