Figure 1. Chemotactic responses of the classical V. cholerae strain O395N1 to bile and bile components.

(a) O395N1 (Che⁺, closed circles) or VcheA2 (∆cheA2, open triangles) cells were subjected to capillary assays with bile. (b) O395N1 cells were subjected to capillary assays with taurine (closed circles), cholic acid (open triangles) and taurocholic acid (closed triangles). Representative data of multiple experiments are shown.
