Group 2 and 3 ABC-transporter dependant capsular K-loci contribute significantly to variation in the invasive potential of Escherichia coli
The major opportunistic pathogen Escherichia coli is the largest cause of antimicrobial resistance (AMR) associated infections and deaths globally. Considerable antigenic diversity has been documented...

Imagine we could travel back in time ⏪⌛️to explore the world of bacterial pathogens before humans discovered and industrialised antibiotics
We just did that to study the history of #AMR spread @science.org

Pre- and postantibiotic epoch: The historical spread of antimicrobial resistance
Plasmids are now the primary vectors of antimicrobial resistance, but our understanding of how human industrialisation of antibiotics influenced their evolution is limited by a paucity of data predati...

New preprint reveals bacteria can't just collect all resistance genes like Pokemon cards.
We found mutually exclusive evolutionary pathways to multidrug resistance in E. coli & P. aeruginosa - some resistance mechanisms actively prevent others from coexisting www.biorxiv.org/content/10.1...

Genomic constraints shape the evolution of alternative routes to drug resistance in prokaryotes
Background Variation within the prokaryotic pangenome is not random, and natural selection that favours particular combinations of genes appears to dominate over random drift. What is less clear is wh...

Being able to data plasmid acquisition, and to see the diversity of plasmids being gained and lost from lineages, was really eye opening! It was a pleasure to contribute my tiny bit to this huge paper and the data has so much more to give! @arredondo.bsky.social @gerrythill.bsky.social et al.

I'm putting together a Microbial Bioinformatics starter pack to help get everyone connected in our community. Let me know if there are any bluesky users to be added and share so that twitter refugees can tune back in to the fantastic world microbes go.bsky.app/3ezLo7e

RTs much appreciated... would love to reach both AMR and biomath folks!
"Evolutionary accumulation modelling in AMR: machine learning to infer and predict evolutionary dynamics of multi-drug resistance"
arxiv.org/abs/2411.00219
We think EvAM methods have some potential in AMR. 🧵

Altmetric is thrilled and also LITERALLY RELIEVED to officially announce:
We are now tracking research attention as it happens on Bluesky!
We have been picking up posts on the site since late Oct.
Our team is on Bluesky all day answering questions.
Let's get into it!

New paper:
We show that population exposure to colibactin producing E. coli lineages ST95 and ST73 largely explains global variation in colorectal cancer incidence. Same STs are also major causes of UTIs and may be similarly involved in urinary tract cancers.
