Oxygen levels can affect how resistance genes work, impacting antibiotic efficacy. This can be relevant for the most used ones: for example, resistance to fosfomycin varies with oxygen.

Excludons are pairs of overlapping genes that block each other’s expression (basically, reverse operons).
We built a tool to identify them in bacterial genomes using transcriptomic data, in an awesome collab led by Iñigo Lasa and Álvaro San Martín.

Four leading researchers on bacterial computing in the @femsmicro.org Workshop on the the topic during the Congress—quite amazing talks by @angelgm.bsky.social, Yolanda Schaerli, Manish Kushwaha & Samgram Bagh. Do bacteria compute? Can we make them to compute wth our logic or do they have their own?
