To explore microbial variations between individuals with NMIBC and MIBC, 2bRAD sequencing (2bRAD-M) was applied to tissue samples from both conditions. The research study enrolled 22 patients with breast cancer (BCa), categorized into 7 cases of non-muscle-invasive bladder cancer (NMIBC) and 15 cases of muscle-invasive bladder cancer (MIBC). DNA extraction was performed on tumor tissue samples that were surgically removed. Microbial genomes for each microbe were enzymatically fragmented using Type IIB restriction endonucleases, which were then mapped to species-specific 2bRAD markers, thereby enabling qualitative and quantitative analyses of microbes across MIBC and NMIBC tissues. Out of all the observed organisms, 527 species were cataloged. Compared to MIBC tissues, NMIBC tissues presented a noticeably larger range of microbial diversity. A consistent microbial structure was seen across the two tumor tissues, with Ralstonia sp000620465 emerging as the dominant species. Acinetobacter guillouiae, Anoxybacillus rupiensis, Brevibacillus agri, and Staphylococcus lugdunensis experienced enrichment in NMIBC, a phenomenon not observed with Ralstonia mannitolilytica, Ralstonia pickettii, and Ralstonia sp000620465 in MIBC. Employing linear discriminant analysis effect size (LEfSe), 252 distinct character taxa demonstrating discrimination were detected. Analysis of species importance point plots revealed Ralstonia sp000620465, Cutibacterium acnes, and Ralstonia pickettii to be the three most important species amongst the two groups. In contrast, the functional annotation analysis revealed the presence of 3011 different COGs and 344 related signaling pathways within the MIBC and NMIBC microbiomes, respectively. The 2bRAD-M microbiome study, initially conducted on MIBC and NMIBC tissues, revealed substantial differences in the microbial milieu, indicating a plausible connection between tumor microbial dysbiosis and BCa, and providing a possible avenue and underpinning for future studies on BCa development and progression mechanisms. This 2bRAD-M microbiome study, focusing on MIBC and NMIBC tissues, demonstrated significant microbial discrepancies between the two groups, suggesting a potential link between tumor microbial dysbiosis and BCa, and offering a target and framework for subsequent research on the mechanisms of BCa development and progression. Through a thorough review of available information, this study sought to evaluate the correlation between the human oral microbiota and COVID-19, and to present a synthesis of the pertinent data accumulated during the pandemic. An exhaustive search for human studies was conducted in EMBASE, PubMed, and the Cochrane Library, encompassing all publications available up to October 2022. The study's main conclusions centred on variations in the oral microbiome's diversity and makeup, specifically at the phylum and genus levels, between individuals with laboratory-confirmed SARS-CoV-2 infection (CPs) and healthy control subjects (HCs). Using the Human Protein Atlas (HPA), GEPIA database, the STRING PPI network, and Metascape analysis, we evaluated the expression of DPP4 (the receptor for SARS-CoV-2) in oral tissues. We sought correlations between DPP4 expression and changes in oral microbiota composition, as well as viral gene expression. Analyzing 9 of the 706 studies, a meta-analysis showed that alpha diversity (Shannon index) was markedly lower in CPs than in HCs. This difference yielded a standardized mean difference (SMD) of -0.53, with a 95% confidence interval (95% CI) from -0.97 to -0.09. Older participants exhibited significantly lower alpha diversity (Shannon index), as indicated by subgroup meta-analysis, compared to younger individuals (SMD -0.54, 95% CI -0.86 to -0.23/SMD -0.52, 95% CI -1.18 to 0.14). Data from six out of eleven and five out of eleven studies, respectively, indicated substantial increases and decreases in the abundances of S
