Thanks for highlighting our work. There’s a couple very slight inaccuracies in the release, so we encourage folks to read the papers, but an excellent synopsis nonetheless! We also do not refute Amy’s thought of intact bacteria in patients, and we’ve ’looked’, the numbers don’t add up…

Rocky Mountain Labs, NIH, is where I did my post doc. Scientists have already been fired, and many more firings will likely follow. A scientific gem is being destroyed 🦠🧫🧪🧬🔬 www.kpax.com/news/ravalli...

A University of Basel study shows that antibiotic failure is due to nutrient-starved Salmonella, not persister bacteria, as traditional methods underestimate surviving bacteria. Researchers suggest focusing on nutrient-related resilience to improve treatments. #AMR www.nature.com/articles/s41...
