The landscape of microbial associations in human cancer www.science.org/doi/10.1126/...

TLDR -- most cancers do not have microbiomes...but a few do have consistent microbe associations (i.e., colorectal and oral cancers). Make sense!
The landscape of microbial associations in human cancer
Differences between cancer types, infectious disease, and potential prognostic markers are uncovered by studying microbes within cancer DNA.

Isolation and characterization of a bacterium affiliated with the hitherto uncultured candidate phylum WOR-3 from a deep-sea hydrothermal fluid | Applied and Environmental Microbiology
Genome analysis from various environments has revealed the overall diversity of microorganisms. However, there are many lineages for which culture representatives do not yet exist, and the characteristics and ecological significance of many of these ...

“Bacterial-MERFISH” provides ~1000-fold volumetric expansion of individual cells, charts gene expression in hundreds of thousands of cells, deciphering bacterial single-cell heterogeneity, intracellular transcriptome organization, and bacterial adaptation to µm-scale niches in vivo
Highly multiplexed spatial transcriptomics in bacteria
Single-cell decisions made in complex environments underlie many bacterial phenomena. Image-based transcriptomics approaches offer an avenue to study such behaviors, yet these approaches have been hin...
