This systematic review examines the transmissibility of Bifidobacterium strains from mothers to infants. Adhering to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, 31 articles from 2009 to 2024 were selected from 2825 screened titles and abstracts. Using a narrative synthesis and meta-analysis, the review focuses on studies employing strain-level metagenomic approaches (Protocol registry CRD: CRD42023490507). Ten studies using shotgun metagenomic sequencing identified specific strains of B. adolescentis, B. angulatum, B. bifidum, B. breve, B. pseudocatenulatum, B. catenulatum, and B. longum shared between mothers and infants. A meta-analysis of 810 mother-infant pairs revealed an overall species transmissibility estimate of 30% (95% CI: 0.17; 0.44), with B. longum strains persisting in infants' guts for up to 6 months. Strain transmissibility was higher in vaginally delivered infants compared to those delivered by caesarean section. This review highlights the high transmission rates of maternal Bifidobacterium strains in early-life gut seeding, particularly B. bifidum and B. longum. Despite ongoing research, uncertainties remain regarding the precise characteristics, transmission routes, and mechanisms of transmitted strains. Comprehensive approaches, including metagenomic sequencing and longitudinal studies, are needed to understand the role of vertical transmission in infant gut microbiome engraftment and its functional implications.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"121"},"PeriodicalIF":7.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144541646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indigenous liquor fermentation typically relies on complex microbiome metabolism, making it difficult to steer fermentation towards consistent high-quality products. Here, we conducted a three-step experiment to identify instability factors and explore ways to steer fermentation stability in lab-scale settings. We found that the metabolic stability of the microbiome fluctuates due to fermentation parameters, dynamic benefit allocation between yeasts and Lactobacilli, and metabolic network redundancy. In addition to parameters control, short-term metabolic stability requires stable microbial benefit allocation, whereas long-term stability requires proper functional redundancy. Rationally setting initial parameters and the microbial inoculation ratio is a practical way to optimize metabolic stability for stable indigenous liquor fermentation. Our study provides new insights into microbiome metabolism control and shows the feasibility of enhancing fermentation stability through appropriate initial conditions, enabling more controlled and efficient microbial food production systems.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"124"},"PeriodicalIF":7.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144541639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

S. mutans, a prominent pathogen of dental caries, is acknowledged for its role in cariogenic biofilm formation, utilizing Sortase A (SrtA) to catalyse surface proteins, thus promoting biofilm formation. In our previous studies, the inhibitory effect of the berberine chloride hydrate (BH) on S. mutans biofilms was confirmed. Here, we further investigate the influence of BH on S. mutans biofilm-induced bovine enamel caries model and explore the effect of BH on S. mutans SrtA activity. We found that BH inhibited S. mutans biofilm formation in bovine enamel model, leading to a reduction in demineralization. Furthermore, we identified and characterized SrtA, which might catalyze SpaP of S. mutans to form fibrillar amyloid aggregates. Our findings showed that BH inhibited SrtA activity by binding to essential amino acid residues LEU-111, MET-123, and ARG-213. BH inhibited amyloid fibers formation by downregulating the expression of srtA gene, thus disrupting S. mutans biofilm formation. Taken together, our study provides new insight into the mechanism of antibiofilm activity of BH and reveals great potential for anticaries clinical applications.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"120"},"PeriodicalIF":7.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144541638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to its ancestor, the variant exhibited shorter generation times, reduced sporulation, auto-aggregation, and lower biomass in mixed-species biofilms.

BV is a dysbiotic condition defined by a deviation from the healthy Lactobacillus dominance to a polymicrobial anaerobic bacterial community that increases the risk of sexually transmitted infections and adverse reproductive outcomes, including spontaneous preterm birth. The increasing number of infectious agents in BV, biofilm persistence and antibiotic resistance in the vaginal canal hinder effective treatments with antibiotics leading to consistent recurrence of BV in many women (30-70%). Like in the gut, these vaginal drug-microbiome interactions termed pharmacomicrobiomics could alter drug disposition, mechanism of action, and toxicity that reduce the efficacy of antibiotics and increase the risk of persistent and recurrent BV and its sequelae. For instance, both vaginal epithelial and bacterial cells co-exist and possess enzymes that metabolize antibiotics, and transporter proteins that expel drugs and toxins, rendering them ineffective. Despite significant progress on pharmacomicrobiomics in the gut, little is known about this phenomenon in the vaginal microenvironment, which harbors a consequential microbiota and a major source of infection and antibiotic resistance. Therefore, to improve therapeutic outcomes and reduce the rate of persistent/recurrent BV and infection-associated preterm birth, we present an overview of the evidence pertaining to the effect of vaginal microbiome-drug interactions and efficacy of antibiotics against recurrent BV. We also highlight plausible mechanistic underpinnings of these interactions and implications for treatment modalities to combat infection-associated preterm birth.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"115"},"PeriodicalIF":7.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144541648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
