Microorganisms and Human Beings


Beneficial activities:

Most microbes are of
benefit to human beings, some are
necessary( nitrogen, carbon cycles, etc)


Harmful activities:

A portion of microbes
cause diseases and are poisonous to human,
and these are really that concern us in the
study of medical microbiology, etc.

Microbiology


Microbiology is the biology of
micro
organism
s
. It is a bioscience for the
study of the evolution, Classification ,

Koch’s postulates




The microbe must be found in the body in all
cases of the disease



It must be isolated from a case and grown in a
series of pure culture in vitro



It reproduce the disease on the inoculation of a
late pure culture into a susceptible animal



The microbe must be isolated again into pure
culture from such experimentally caused
infection.
