The strain has spontaneous loss of function of fliI and behaves the same also after motA deletion. Pic left: 0.5% agar and pic right: 0.5% agar + 0.5% glucose.

A few years back we were developing a motility screen and were left puzzled by an immotile E. coli that does not swim but somehow "crawls" on agar with glucose and was inhibited by surfactant... In retrospect - it might be swashing, just the type of motility was not yet described 😅 Pics in comments.
