WebThe loss-of-function mutation in hfq led to pleiotropic phenotypic effects, including an altered bacterial growth rate and reduced adherence to epithelial cells. Twitching motility and microcolony formation were not affected. Hfq also appears to play a minor role in inducing the inflammatory response of infected human epithelial cells.
