Bacterial Mobile Evolution. Staff Scientist at Sanger Institute. I study how pathogens emerge and evolve by sharing genes. Interested in AMR, Plasmids, Phages, ICEs, and everything that moves within and between genomes.

Happy to share that our latest research on the eco-evolutionary dynamics of MDR plasmids and PDPs is now out (open access vAuthor) in The ISME Journal doi.org/10.1093/isme... Here, we explored how plasmid-dependent phages (PDPs) act as a selective pressure against the spread of multidrug resistance

Eco-evolutionary responses to plasmid-dependent phage constrain the spread of multidrug resistance plasmids

Abstract. Phage therapy offers a promising alternative to antibiotics for treating multidrug-resistant infections. Plasmid-dependent phages (PDPs) are part

Out in @natcomms.nature.com! We show that while most MGEs are blocked by RM systems🛡️, the chromosome is still mobile! 🧬And that cells with defective systems act as "gateways" for HGT. Can you find the hidden Easter egg🐇🥚? Hint: There's a nod to my 🇲🇽 heritage in one of the figures! rdcu.be/fbUC8

Immune-deficient bacteria serve as gateways to genetic exchange and microbial evolution

Nature Communications - The efficiency of horizontal gene transfer between different bacterial lineages is often unclear. Here, Figueroa et al. show that lateral transduction is the primary driver...

New preprint! Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠 Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare! An epic effort by Rosanna Wright www.biorxiv.org/content/10.1...

Resistance mutation supply modulates the benefit of CRISPR immunity against virulent phages

Only a fraction of bacterial genomes encode CRISPR-Cas systems but the selective causes of this variation are unexplained. How naturally virulent bacteriophages (phages) select for CRISPR immunity has...

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 doi.org/10.1126/scie... If you like time travel & biology, this 🧵is for you👇

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...
