<i>Legionella</i> affects biofilm structural response to detachment upon shear stress increase.

ABSTRACT: Poor hydraulic management at water systems is associated with an increased risk of Legionnaires' disease caused by Legionella. Stagnation periods, followed by sudden water flow, can promote biofilm detachment and the release of Legionella into the bulk water. Regardless of its importance, the simultaneous effects of shear stress on biofilm detachment and Legionella release into the bulk water remain poorly understood. This study investigates how shear stress affects biofilms containing Legionella pneumophila in terms of: a) biofilm detachment, b) release of L. pneumophila into the bulk phase, and c) shifting of L. pneumophila into the viable but nonculturable (VBNC) state. Pseudomonas fluorescens biofilms were formed in a Center for Disease
