Motility, and in particular directed motility, is decisively important for host colonization, as bacteria deliberately seek to colonize an organism and conquer all niches.

*shudders* The article is about stress hormones in people, and research into how bacteria are (not “may be”) using our hormones to signal when they (the bacteria, *shudder* again) should go on the offensive and move. I don’t have anything to add. This just struck me as creepy.
