Introduction to Microbiology and Parasitology Flashcards
study of living organisms
Biology
advanced biology course and study of microbes
Microbiology
Living microbes are known as
Cellular microbes
Non-living microbes are known as
Acellular microbes
examples of cellular microbes
bacteria
archaea
protozoa
some fungi
some algae
examples of acellular microbes
viroids
prions
viruses
microbes that cause disease are sometimes referred to as
germs
scientific term or disease causing microbes is
pathogens
microbes that do NOt cause disease are called
non-pathogens
microbes that live on and in our bodies are referred to as
Indigenous microflora
some members of indigenous microflora are
Opportunistic pathogens
microbes that can cause disease, but usually do NOT, and microbes that are awaiting the opportunity to cause disease
Opportunistic pathogens
2 Categories of Diseases Caused by Pathogens
Infectious disease
Microbial disease
Many microbes play essential roles in various elemental cycles; examples are?
Carbon
Nitrogen
Oxygen
Sulfur
Phosphorus
serve as food for tiny animals; they are important links in food chains
algae and bacteria
For many years, microorganisms have been used as
“cell models”
microbes are used in many industries; examples are
food
beverage
chemical
antibiotic industries
genetic engineering
candidates for the first microorganisms on earth are
archaea and cyanobacteria
Earliest known account of pestilence occured in
Egypt in about 3180 BC
Father of Microbiology
not a trained scientist
made many simple single lens microscopes
observed “animalcules”
Anton van Leeuwenhoek(1632-1723)
French Chemist
investigated diff. fermentation products
developed the Pasteurization process
discovered the life forms that could exist without oxygen
developed several vaccines, including rabies and anthrax vaccines
Louis Pasteur(1822-1895)
German physician
made significant contributions to the germ theory of disease
discovered that Bacillus anthracis produced spores
developed methods of fixing and staining bacteria
developed methods to cultivate bacteria
Robert Koch(1843-1910)
