ScienceDaily (Jan. 11, 2010) Bacteria can swim, propelling themselves through fluids using a whip-like extension called a flaggella.
They can also walk, strolling along solid surfaces using little fibrous legs called pili.
It is this motility that enable some pathogenic bacteria to establish the infections -- such as meningitis -- that cause their human hosts to get sick or even die.
