disease producing microbes.
- also referred to as “infectious agents”
Pathogen
microbes that do not cause disease.
Nonpathogens
Known as infectious particles
Acellular microbes
Ex: prions and viruses
Cellular microbes
a. ) prokaryotes (organisms composed of cells that lack a true
nucleus) . Ex. Achaea and Bacteria
b. ) eukaryotes ( organisms composed of cells that contain a true nucleus). Ex. Algae, protozoa, fungi
these are microbes that live on and in the human body.

microbes that do not cause disease under ordinary conditions, but have the potential to cause disease should the
Opportunistic pathogens
The study and classification of microorganisms and how they function.
General Microbiology

Veterinary Microbiology

studies of different microorganisms that are both harmful and or beneficial in soil formation and fertility.
Agricultural Microbiology
This includes processing and disposal of garbage and sewage waste as well as purification and processing of water supply.
Sanitary microbiology
Industrial Microbiology
Businesses and industries
Microbial Genetics
Study of function and structures of DNA
- made more than 500 microscopes.
- Father of Microbiology.
Antony van
First to see live bacteria and protozoa.
Antony van
discovered fermentation
introduced the aerobes and anaerobes”
he developed a process known as PASTEURIZATION
Louis Pasteur
he discovered the infectious agent that caused the silkworm diseases
made significant contribution to the GERM THEORY OF DISEASE
developed vaccines
Louis Pasteur
proved that anthrax bacillus (B. anthracis) is the causative agent of anthrax.
- developed methods of fixing, staining and photographing bacteria.
Robert Koch
developed methods of cultivating bacteria on solid media.
- introduced the term PURE CULTURE
Robert Koch
Developed the process of
Tyndallization
John Tyndall
Developed the Concept of Aseptic Technique
he instituted the practice of using phenol (carbolic acid)
He made surgeons wear gloves and wash their hands
before and after operations with carbolic acid diluted in water
