摘      要：The motion of small bacteria consists of two phases:relatively long runs alternate with intermittent stops,back-ups,or tumbles,depending on the *** polar monotrichous bacteria,the flagellum is anchored at the cell pole inherited from the parent generation(old pole) and is surrounded by a chemoreceptor *** forward swimming,the leading pole is always the pole recently formed in cell division(new pole).The flagella of the peritrichous bacterium Escherichia coli often form a bundle behind the old *** cell orientation and receptor positioning during runs generally mimic that of monotrichous *** encountering a solid surface,peritrichous bacteria exhibit a circular motion with the leading pole dipping *** polar monotrichous bacteria also perform circular motion near solid boundaries,but during *** this case,the leading pole points *** little is known about behavior near milieu-air *** simulations have revealed some of the mechanisms underlying these phenomena,but leave many questions *** biophysics with molecular techniques will certainly advance our understanding of bacterial locomotion.
