What is Microorganisms
 Microorganisms are creatures that are not
directly visible to the unaided eye, with
dramatical biologic diversity.
 Viruses , bacteria, fungi, protozoa and some
algae are all in this category
 All with the exception of plants and animals
Distribution of microorganisms

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.
The Importance of Microbiology

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.
