Haven't read the paper yet. But I expect to see a control where they plate the same starter culture directly on each log scale antibiotic concentration (1,10,100,1000) to see if it contained resistant bacteria from the get go. Thus testing if resistant mutants were always present in a population or they arise and are selected for by evolutionary process.
It is the origin of mutants that is the more interesting question.
- Retric 10y agoThe video shows mutations in real time as bacteria grow or fail to grow in various places. https://www.youtube.com/watch?v=plVk4NVIUh8 https://www.youtube.com/watch?v=plVk4NVIUh8 It's more a demonstration than experiment, but visually it's just really striking.
