Despite geographic differences in microbiota composition, patients with COVID-19 in both continents exhibited significant gut microbiota alterations, which were more pronounced in severe cases, with similar features compared with controls. Functional pathways, including L-Tryptophan biosynthesis, were disrupted, particularly in patients with severe disease.

In early-stage cervical lesions, the HPV 16/18 group showed reduced Lactobacillus-dominant community state types compared to other HR-HPVs, while invasive CC exhibited increased pathogenic bacteria, including Streptococcus agalactiae, Fannyhessea vaginae, and Sneathia vaginalis. The VM associated with HPV 16/18 was enriched in immune response and inflammation pathways, whereas other HR-HPVs were linked to cellular metabolism and hormonal signaling. Notably, HPV 16/18 exhibited stronger bacterial-fungal correlations, indicating shifts in the microbial community. Furthermore, 137 metagenome-assembled genomes provided insights into unique microbial genomic signatures.

An accepted mathematical model based on one-dimensional balances with diffusion-reaction of substrates and convection of multiple microbial types in a cross-feeding biofilm was used to describe emerging microbial distributions. The model allowed isolation of the effects of diffusion from other factors (kinetics, stoichiometry, specific symbiotic interactions), pointing to a possible mechanism for stratification in anaerobic biofilms. The secondary degrader consuming waste metabolite from a primary degrader was retained in anaerobic biofilms in an apparent growth yield disproportion. However, diffusion of an intermediate substrate can be responsible for this disproportion, even in longer food chains. This microbial distribution was not observed in independent feeding. In aerobic biofilms, this mechanism remains inactive, explaining the preference for full oxidation of organic matter in aerobic degradation.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"102"},"PeriodicalIF":7.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12159163/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144275493","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}

Yet, research on the urbanization impact on environmental and host-associated microbiomes, particularly on the ecological processes that mediate their assembly and function, remains scarce. This study investigated the effects of an urbanization gradient on the diversity and assembly processes of the soil microbiome and the microbiomes of three epiphytic lichen species (Candelaria concolor, Physcia adscendens, and Xanthoria parietina). Our findings revealed that the urbanization gradient shaped the soil microbiome, while the lichen microbiomes exhibited strong host specificity and showed no significant changes in diversity along the urbanization gradient. Heterogeneous selection and dispersal limitation primarily governed the soil community assembly and higher community turnover in medium- and highly urbanized zones compared to low-urbanized zones, indicating an increased influence of environmental pressures, altered resources, and habitat fragmentation in more urbanized areas. The lichen microbiome assembly in each species was primarily governed by undominated processes regardless of urbanization level, indicating that both selection and stochasticity contributed to, but neither dominantly influenced, their assembly. The lichen microbiomes further revealed species-specific co-occurrence networks, with microbial compositional signatures and potential functions being essential for lichen fitness and urban ecosystem health. Taken together, our study contributes to understanding how microbial communities are assembled in urban environments, bridging the gap between conceptual theories and empirical findings in the urban ecology of soil and lichen-associated microbiomes.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"99"},"PeriodicalIF":7.8,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152141/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266918","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}

We investigated the recolonisation of pre-formed live biofilms and the residual matrix left behind after bacterial eradication with N-acetyl cysteine (NAC). P. aeruginosa ΔmucA, which overproduces alginate, prevented recolonisation through swelling and increased elastic modulus. In contrast, the wild-type P. aeruginosa biofilm matrix exhibited minimal swelling and decreased elasticity, suggesting crosslink breakage. These observations align with polymer physics theories where alginate's polyelectrolyte nature drives swelling through the Donnan effect, enhancing matrix stability. Meanwhile, the Psl-rich wild-type matrix limited swelling but showed reduced mechanical stability. This study underscores the critical role of matrix composition in biofilm mechanics, influencing bacterial protection regardless of viability.","PeriodicalId":19370,"journal":{"name":"npj Biofilms and Microbiomes","volume":"11 1","pages":"98"},"PeriodicalIF":7.8,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149293/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144258628","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}
