- Scientists: Infection Control - -John Snow
,- Scientists: Etiology - -Robert Koch
- Scientists: Epidemiology - -John Snow
- Scientists: Biotechnology - -Louis Pasteur
- Scientists: Food microbiology - -Louis Pasteur
- Developed smallpox immunization - -Edward Jenner

Christian Gram
- Leeuwenhoek's observations of microbes introduced most types of
microorganisms to the world. HIs discoveries were names and classified by
who and in what system? - -Linnaeus in his taxonomic system
- Small prokaryotes (bacteria and archaea) live in a variety of communities
and most habitats. Are most harmful or beneficial? - -Most are beneficial,
some cause disease
- Molds and Yeasts - -large microscopic eukaryotic fungi
- Animal-like protozoa - -single-celled eukaryotes, some cause disease
, - Plantlike eukaryotic algae - -important providers of oxygen
serve as food for many marine animals
make chemicals used in microbiological growth media
- Parasitic worms - -largest organisms studies by microbiologists, often
visible without a microscope, although their immature stages are
microscopic
- Viruses - -the smallest microbes, so small they can be seen only by using
an electron microscope
- The study of the Golden Age of Microbiology includes a look at the men
who proposed or refuted the theory of spontaneous generation: - -Aristotle,
Redi, Needham, Spallanzani, and Pasteur (Father of Microbiology). The
scientific method that emerged then remains the accepted sequence of
study today
- The study of fermentation by Pasteur and Buchner led to the fields of
what? - -Industrial microbiology (biotechnology)
biochemistry
study of metabolism
- Koch, Pasteur, and others proved that _____ cause infectious diseases, and
idea that is knows as the _______ theory of disease. ___________ is the study of
the causation of diseases. - -1. pathogens
2. germ theory of disease
3. Etiology
- Koch's Postulates - -The logical steps he followed to prove the cause of an
infectious disease, remain an important part of microbiology today.
1. The suspected causative agent must be found in every case of the disease
and be absent from healthy hosts
2. The agent must be isolated and grown outside the host
3. When the agent is introduced to a healthy, susceptible host, the host must
get the disease
4. The same agent must be found in the diseased experimental host

to differentiate bacteria into two categories - -Gram stain
Gram positive and Gram negative
- The investigations of Semmelweis, Lister, Nightingale, and Snow are the
foundations on which ___________ ___________ are built. - -infection control,
including control of healthcare-associated infections (HAI), and epidemiology
