Introduction Microorganisms(Microbes) Microbiology Medical Microbiology
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 Air Soil Water Animals Human body
100m 300m 1400m 2100m 3150m 4050m 6000m
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 Environment Medicine Food Industry Biotechnology Research

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.
Emerging and Reemerging Infectious Disease AIDS Tuberculosis Hepatitis Gastric ulcer SRAS
Medical Microbiology The medical microbiology is one of the essential basic sciences for medine. It is the study of Biological characteristics of microorganisms and their relationships with human hosts Medical Bacteriology Medical Viriology Medical Mycology Parasitology Immunology
