Turns out the order of your scRNA-seq QC pipeline matters more than we thought: removing ambient RNA before doublet detection can reduce doublet detection performance!

New research suggests that the risk of developing bacterial pneumonia, sepsis, and meningitis after air pollution exposure could depend on the subtype of bacteria a person has.

Big paper alert! This project has been years in the making. A comprehensive description of somatic mutation rates and signatures across 53 tissues or cell types using NanoSeq. A large collective effort led by Mimy Pham, Mike Stratton and @r-rahbari.bsky.social. www.biorxiv.org/content/10.6...
Glad to share StrainSpy, a new method developed by Sudaraka and co which identifies strain-level associations in metagenomics using ANI estimates from tools like Sylph. www.biorxiv.org/content/10.6...
StrainSpy’s GLMM framework enables straightforward integration of large, multi-cohort microbiome studies. Re-analysis of a large colorectal cancer dataset identified both known and novel strain-level associations, including in E. coli, with an accompanying enrichment of adhesin-encoding genes.
Beyond association testing, we found that StrainSpy-derived cANI features led to similarly accurate downstream machine learning models as comparable abundance based approaches. Thanks very much to all our co-authors including @danielleingle.bsky.social and others not on Bluesky

Inspired by @jimshaw.bsky.social's Sylph paper, StrainSpy makes it easier to apply association tests to ANI estimates. Applying it to a well-characterised study of antibiotic exposure identified sub-species perturbations that would have been obscured by species-level abundance methods.
Exciting collaboration with @annabiosys.bsky.social's lab just went online. @isbscience.org

Happy to share the latest work from Zunair Khurram, a PhD student in our lab! Zunair has developed a new method, MxSure, to infer within-host substitution rates and transmission thresholds from longitudinal isolate and metagenomic sequencing data.
www.biorxiv.org/content/10.6...
Using MxSure, we estimated within-host substitution rates and transmission SNP thresholds for multiple commensal bacterial species, including Bifidobacterium longum and Bifidobacterium bifidum.

In addition to accurately identifying strain replacement events in S. pneumoniae, we show that phylogenetically informed thresholds outperform methods that do not model the underlying evolutionary process, such as Youden's J statistic, which is often used in metagenomic transmission studies.

A preprint reports that the predictions are based on splice variants. Using only this info (no sequences, no AI) achieves AUROC=0.944 across noncoding variants.
