1. Besides we see around us with naked eyes ,a group of point diameter
micro world surrounds us & affect all lives can be visible only under
microscope. This whole minute sized world attract us by causing
sometimes beneficial & sometimes harmful effects in numerous ways
like in formation of fermented food products, antibiotics as their
beneficial & by causing hazardous diseases in the form of endemics &
epidemics through out world as harmful effects. This group of
microorganisms is studied in branch of life science known as
microbiology which is classified in so many branches according to
category show same characters .These micro sized organisms are
ubiquitous in nature & also survive in dormancy in human, plant &
animals hosts for years & suddenly appear as severe illness .
This microscopic world was first discovered by
Louise Pasteur known as father of microbiology in laboratory in terms
of fermentation & Antony von Leuwan hock described bacteria as first
discovered microbe after a long experiment. In sequence of it, so many
genera, classes, strains & species are discovered by renowned
microbiologists. In spite of being minute size, they cause & spread
severe infectious diseases in flora & fauna. Large epidemics occur due
to these organisms with high mortality rates which are incurable &
even can’t be prevented.

2. Invention of new vaccines is the result of discovery of this micro world.
Years passed & except bacteria, viruses, fungi, many other organisms
were discovered. Cholera, tetanus, cancer, hepatitis are examples of
most hazardous diseases are caused by them.Time to time their
preventive measures are taken as prior oral & intravenous vaccination
in new born up to the age of one year.
In this sequence, now hepatitis like most severe & late detectable
cancer can be prevented & treated if it is detected in time. So big
problem can be created by these organisms which can be
communicable in generations in dormancy & can be visible on being
dominate on least immunity state of an individual & sometimes
genetically transfer generations to generations if not treated well.
This vast field of studies in medical science till now covered with the
gradual studies & discoveries of organisms & diseases caused by them
with subsequent discoveries of vaccines & inventions of instruments
related with their studies.
So as you see ,how a point diameter life in atmosphere equally special
& root of various important discoveries & inventions in medical field by
well known scientists through out the world.
