Detailed explanation-1: -Bacterial flagella are filamentous organelles that drive cell locomotion . They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments.
Detailed explanation-2: -The flagellar motors of E. coli and Salmonella rotate in both counterclockwise (CCW) and clockwise (CW) without changing the direction of ion flow. E. coli and Salmonella cells can swim in a straight line by bundling left-handed helical filaments behind the cell body (run) when all of them rotate in CCW direction.
Detailed explanation-3: -Examples of flagellate bacteria include Vibrio cholerae and Campylobacter jejuni, which use multiple flagella to propel themselves through the mucus lining of the small intestine to reach the epithelium and produce toxin.
Detailed explanation-4: -Flagella propel bacteria through the body The flagellum has three components-the motor, hook, and filament. The rotation of the filament allows bacteria to move around in their environment.
