Brownian Motion
Brownian movement is caused by the molecules of a suspending liquid colliding with an organism, moving it around in a completely random fashion. If the liquid is flowing in one direction, however, the motion may not appear random. True motility is directional and goal-oriented, such as pursuing the chemical trail of a food source or moving towards light. The motility is controlled by the organism, not by chance.
Staphylococcus epidermidis belongs to the genus Staphylococcus. It is part of the human skin flora and is a non-motile bacterium.
Should be flagellar motion since it has falgella
it is called the atomis it is called the atomis
the movement of bacteria which posses flagella. Flagellar motion is considered to be true motility.
The Brownian movement is a result from random motion of water molecules that bombard the bacteria and causes the bacteria to move. True motility involves the 3 modes of motility and self propulsion does so as well.

Just by the sheer fact that any vibration of any kind can be considered Brownian motion for a hanging drop test. the longer you observe your bacteria, the more chance there are of Brownian motion interfering with your motility test ( I assume you're talking about the motility hanging drop, right?). It is because of this fact that the hanging drop test is quickly falling out of favor for more secure tests for motility, the semi-solid media being one of them.
Brownian motion is the random moving and mixing of particles.

The haphazard motion of particles of matter is called brownian motion.
