      Hi,

      I have a question considering a swarming assay on E.coli…
      I did a soft agar (0.3%), in LB, and placed a drop of bacteria in the middle of a plate. But after 24h, they just grew in a small radius, like in the photo:

      DO you think I have non-motile E.coli? Cause I would expect a bigger circle. Or Im just doing something wrong…
      How is this different from a swimming assay?
