The final AMR Digest of 2023 features microbial wars and weaponry evolution, “plastisphere” as a new home for bacterial communities, inter-phylum ARGs exchange, peculiarities of honeybee and stray cats microbiota, and how the distance that your steak travels before ending-up on your plate is related to MDR contamination. And much more!

Gene Transfer/Plasmids
Inter-phylum circulation of a beta-lactamase – encoding gene: a rare but observable event – Rémi Gschwind, Marie Petitjean, Claudine Fournier, Julie Lao, Olivier Clermont, Patrice Nordmann, Alexander Mellmann, Erick Denamur, Laurent Poirel, Etienne Ruppé – bioRxiv preprint
*While transfer of beta-lactamase encoding genes typically occurs between closely-related bacteria, the research documents a unique case of inter-phylum transfer between the Peudomonadota and Bacteroidota phyla. The investigation focuses on an extended-spectrum beta-lactamase (ESBL)-encoding gene, blaMUN-1, from an Escherichia coli strain. This study marks the first reported instance of inter-phylum transfer of an ESBL-encoding gene, indicating that while inter-phylum barriers are generally robust, they are not insurmountable.
