X. fastidiosa mutant TM14 (pilY1) is shown moving via
type IV pili twitching-motility (right to left) against a stream of medium
flowing 50,000 μm per minute from left to right in a microfluidic
chamber. Cells observed travelling from left to right are either floating
free with the medium or they are dragged on the chamber surface with the
flow of medium.
