A bacteria that fooled us Published today; open-access: * Spiga et al. [An anaerobic pathogen rewires host metabolism to fuel oxidative growth in the inflamed gut: Cell](https://www.cell.com/cell/fulltext/S0092-8674\(26\)00401-0)   It's an instance of an [extended phenotype](https://pmc.ncbi.nlm.nih.gov/articles/PMC2658563/), like the [fungus](https://www.reddit.com/r/evolution/comments/1lly441) I've previously shared that manipulates the host into overfeeding. This bacteria was thought to be anaerobic, which was puzzling since it thrives in oxygen-rich environments, but as it turns out, it was cryptically aerobic, and it manipulates the host into creating an oxygen-rich environment, to kill the competition: > How ETBF, a classically anaerobic pathogen, successfully persists in the inflamed, oxygen-enriched gut it induces,50 has remained unclear.…
