Abstract: | Background Pathogenic Leptospira species cause leptospirosis, a zoonotic disease of global importance. The spirochete displays active rotative mobility which
may contribute to invasion and diffusion of the pathogen in hosts. FliY is a flagellar motor switch protein that controls
flagellar motor direction in other microbes, but its role in Leptospira, and paricularly in pathogenicity remains unknown. |
