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
microorganisms. It is a bioscience for the
study of the evolution, Classification ,
morphology, physiology, genetics, ecology of
microbes under certain definite conditions,
The law of their life activities, and their
interaction with human being, animals or
plants as well as with natural environment.

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.
