Description Understanding the pathogen and the pathogenesis at cellular levels are imperative in the studies
of disease causing organisms. With its very high resolving and magnifying powers, Electron
Microscopy has opened up new vistas in studying the ultra structure and has become an indispensable
tool in understanding many of the diseases and their etiological agents. The limitations of Light
Microscopes, low magnifying and resolving powers (1000 x magnification and a resolution of 0.2
micrometers) paved the way for the development of electron microscopes. Electron Microscopes
are instruments that use a beam of highly energetic electrons to examine objects on a very fine
scale and function exactly like their optical counterparts. Present day electron microscopes are
capable of giving magnifications up to 1000000 X and 800000 X and a resolving power of 0.1 nm
and 0.4 nm in T E M and S E M respectively. Transmission electron microscopy (TEM) can reveal
the ultra structural details at cellular levels, whereas Scanning electron microscopy (SEM) can show
the morphology of minute structures/organisms in its three-dimensional state. Combining the TEM
and SEM, it has become possible to study and classify the viruses and virus like organisms.
