WebCharacteristic rapid darting motility by means of long sheathed polar flagellum at one (polar) or both (bipolar) ends of the cell that may be up to several times the length of the cell (see WebLinked image); motility slows quickly in wet mount microscopy preparation due to entangling of flagella and aerotoxicity (oxygen sensitivity) On the basis of the involvement of flagella in motility, bacterial motilitycan be divided into two main categories: (a) Motility involving flagella:The modes of bacterial motility which involve the function of flagella include swimming, swarming, darting, and cork-screw motility. (b) Flagella-independent motility:The … See more Brownian movement:Brownian movement in relation to bacterial motility is defined as the collision of micro-organisms, i.e. bacteria with the water molecules in the aqueous environment. This type of collision between … See more There are several reasons which make the bacteria motile.
