Abstract
As a preliminary experiment, the motion of Vibrio is observed by use of dark field microscope with CCD camera and its image is recorded to video recorder, By using NIHImage, the video image is digitized and the position as well as inclined angle of bacterial cell is obtained numerically. It is shown that variations of the speed and the frequency of wobbling motion of the bacterium can be obtained. In the analytical study, a computational procedure is developed to simulate wobbling motion of bacteria with single helical flagellum, the axis of which is inclined to major axis of the bacterial cell. The resistance force theory is employed to estimated force exerted on rotating flagellum.
