Intro to Microbiology Flashcards
The first to use a lens to observe the smallest unit of
tissues he called “cells”
Robert Hooke
The first person to observe and accurately
describe microorganisms (bacteria & protozoa)
called “animalcules” (little animals)
Anton van Leeuwenhoek
States that life arose from nonliving matter
Theory of spontaneous generation
Father of handwashing
Ignaz Philipp Semmelweis
Infection control
Handwashing
Father of modern epidemiology
John snow
Demonstrated that different types of microbes produce different fermentation products
Louis Pasteur
Disproved theory of spontaneous generation/ abiogenesis (life can arise spontaneously from non-
living materials)
Louis Pasteur
Heating liquids to - for 30 minutes
63 - 65°C
Heating liquids to _ for 15 seconds
73 - 75°C
Type of sterilization, only kills pathogens
Pasteurization
Specific microbes cause specific infectious
diseases
Germ theory of disease
Germ theory of disease help developed vaccines to prevent
Chicken cholera, anthrax, and swine erysipelas
Made many significant contributions to the
germ theory of disease
Robert Koch
Bacteriums discovered by Robert Koch
m. tuberculosis, vibrio cholerae
Robert Koch Discovered that ___ produces spores, capable of resisting adverse conditions
B. anthracis
First proposed the use of agar in culture media
Fanne Eilshemius Hesse
Developed the Petri dish (plate), a container used
for solid culture
Richard petri
Provided the initial evidence that some of the
microbes in dust and air have very high heat
resistance and that particularly vigorous
treatment is required to destroy them
John Tyndall
Aseptic techniques using physical & chemical
agents
Joseph lister
Vaccination , smallpox vaccine
Edward Jenner
Phagocytic theory of immunity
Elie metchnikoff
Developments of chemotherapy
Paul Ehrlich
the first antibiotic penicillin
Alexander flemming
Streptomycin
Seaman Waksman
Is an area of biologic science that compromises three distinct but highly interest interrelated disciplines
Taxonomy
3 interrelated disciplines of taxonomy
Classification, nomenclature (naming), and identification of organisms
method of classification that combines the
traditional genotypic, phenotypic, & phylogenetic
or evolutionary relationships into a general
purpose classification system
Polyphasic taxonomy
Provides a more detailed but very complex analysis of the current classification system
Polyphasic taxonomy
A method for organizing microorganisms into groups or taxa based on similar morphologic, physiologic, and genetic traits
Classification
Contain the environmental prokaryotes und the heterotrophic medically relevant bacteria
Bacteria
Are environmental isolates that live in extreme environments
Archaea
