(rod-shaped bacteria) Spirilla (spiral bacteria).

Which is the smallest bacteria in the world?
Mycoplasma genitalium is the smallest known bacteria. The size ranges
from 200 to 300 nm. It is a parasite.

Who named the cell?
Hooke detailed his observations of this tiny and previously unseen world in
his book, Micrographia. To him, the cork looked as if it was made of tiny pores,
which he came to call “cells” because they reminded him of the cells in a monastery.
Who is father of virus?
Martinus Beijerinck is often called the Father of Virology. Beijerinck's
laboratory grew into an important centre for microbiology.


Who found virus?
Beijerinck, in 1898, was the first to call 'virus', the incitant of the tobacco
mosaic. He showed that the incitant was able to migrate in an agar gel, therefore
being an infectious soluble agent, or a 'contagium vivum fluidum' and definitively not
a 'contagium fixum' as would be a bacterium.
