Swimming of Bacteria at low Reynolds numbers is relatively well understood. Much less is known about bacteria crawling on surfaces. In particular as some species leave sticky trails that are believed to help them coordinate. I will introduce a simple semi-microscopic model for the bacteria-trail interaction. Based on this model I will discuss the effects of the trail-mediated self-interaction on a single bacterium and whether or not it actually allows trail-following behaviour.
