Strain-level translocation and enrichment dynamics of oral bacteria in the lower gastrointestinal tract of stunted children
Emerging evidence suggests that ectopic colonization of oral bacteria in the lower digestive tract may exacerbate gastrointestinal disorders. Nevertheless, it remains unclear whether bacteria of or...

🐝🦠 New paper: rdcu.be/eOf7A Phages may drive microbial diversity, yet we often don’t even know how phages & bacteria correlate in nature. Our new study tackles this in the honeybee gut, thanks to the great work of PhD student @malickndiaye.bsky.social at @dmf-unil.bsky.social @fbm-unil.bsky.social

In the review, we discussed strain-sharing and spreading of antimicrobial resistance (AMR) genes within and across domains as well as overall microbiome diversity and resilience to climate change and how this is influenced by the One Health concept.

You can get an accurate estimate of total bacterial biomass from stool metagenomes by simply normalizing by host read count, without needing any additional measurements. Excellent work by UW Master's student Gechlang Tang in @asm.org #mSystems Journal. journals.asm.org/doi/10.1128/... 🧵
