Lesson 3: History of Microbiology, a walk through the past Flashcards
he introduced the Theory of Spontaneous Generation
Aristotle (384 BC- 322 BC)
states that life come from non-living matter
Theory of Spontaneous Generation
there were some intellectuals that believed were not able to provide proof.
Lucretius
Girolamo Fracastoro
developed an experiment which demonstrated that organisms did not spontaneously appear.
Francesco Redi
He hypothesized that maggots come from flies. He filled jars with rotting meat
Francesco Redi
popularized the use of compound microscope
Robert Hooke
first invented the compound microscope, a dutch spectacle-maker.
Zacharias Janssen
he was the first person to use the word “cell” to identify microscopic structures when he was describing cork.
Robert Hooke
Robert hooke featured many drawings, some of which have been attributed to;
Christopher Wren
a merchant of textiles and an amateur lens grinder, to get interested in microscope.
Antony van Leeuwenhoek
he improved Hooke’s microscope by grinding lenses to achieve magnification.
Antony van Leeuwenhoek
he became the first person to view living microorganisms, so tiny that they were invisible to the naked eye, which he called “ANIMALCULES”.
Antony Van Leeuwenhoek
father of microbiology
Antony Van Leeuwenhoek
he showed that microorganisms are present in the air.
Louis Pasteur
He proved that sterilized medical’s equipment became contaminated once they were exposed to the air.
Louis Pasteur
one of the best known sterilization techniques, was developed and named after Louis Pasteur.
Pasteurization
they led to one of the most important discoveries in sterilization and bacteriology.
John Tyndall and Ferdinand Cohn
They discovered the thermoresistant phase of bacteria to boiling temperatures.
John Tyndall and Ferdinand Cohn
he discovered that bacteria existed in two forms: a heat-stable form and a heat-sensitive form, and that prolonged or intermittent heating called Tyndallization destroys heat stable form of bacteria.
Tyndall
He discovered that these heat-stable forms are spores which develop into microorganisms in inadequately heated infusions
Ferdinand Cohn
he observed that communicable diseases were caused by invisible creatures called contagion be it by direct or indirect contact
Girolamo Fracastoro
belief that infections are caused by bad air went on for years.
miasma theory
states that living matter is generated from another living matter gained popularity.
theory of biogenesis
which states that microorganisms or germs can lead to a disease in humans, animals or other living hosts.
Germ Theory of Disease
saved lives by encouraging fellow doctors to wash their hands after performing autopsy and before proceeding to deliver a baby.
ignaz semmelweis
suggested to filter and boil water before use, short after he suggested that a “cell” is causing the disease.
John Snow
believed that cholera is transmitted by water contaminated with waste of other cholera patients.
John Snow
who first conducted formal experiments to promote germ theory of disease with his experiment on fermentation of wine.
Louis Pasteur
he also credited for his discovery of weakened or attenuated vaccine against fowl cholera, anthrax for small ruminants and rabies.
louis pasteur
elaborated the theory and practice of antiseptic surgery, which included washing the hands with carbolic acid to prevent infection. Known as the Father of modern Antisepsis
Joseph Lister
what germ does Robert Koch successfully linked?
Bacillus Anthracis (anthrax and mycobacterium bacillus)
