his findings were a serious blow to the long-held belief that large forms of life could arise from nonlife

HISTORY OF MICROBIOLOGY:
observed that boiled mutton broth eventually cloudy with microorganisms after pouring it into a flask and sealed tightly
John Needham (1748)
HISTORY OF MICROBIOLOGY:
proposed that organic matter possessed a “vital force: that could give rise to life
John Needham (1748)
HISTORY OF MICROBIOLOGY:
improved the previous experiments of Needham by heating the broth placed in a sealed jar
Lazarro Spallazani (1729-1799)
HISTORY OF MICROBIOLOGY:
observed that no growth took place as long as the flasks with broth remained sealed
Lazarro Spallazani (1729-1799)
HISTORY OF MICROBIOLOGY:
proposed that air carried microorganisms to culture medium and that might be the reason for the growth of organisms present already in the medium
Lazarro Spallazani (1729-1799)
HISTORY OF MICROBIOLOGY:
concluded that microorganisms from the air probably had entered Needham’s solutions after they were boiled
Lazarro Spallazani (1729-1799)
HISTORY OF MICROBIOLOGY:
showed the importance of oxygen to life
Laurent Lavoisier
HISTORY OF MICROBIOLOGY:
concept of living cells arising only from preexisting living cells
Biogenesis
HISTORY OF MICROBIOLOGY:
challenged spontaneous generation with the concept of “biogenesis”
Rudolf Virchow (1858)
HISTORY OF MICROBIOLOGY:
observed that no growth occurred in a flask containing nutrient solution after following air to pass through a red-hot tube
Theodore Schwann (1810-1882)
HISTORY OF MICROBIOLOGY:
resolved the issue of spontaneous generation
Louis Pasteur (1882-1895)
HISTORY OF MICROBIOLOGY:
stated that microorganisms are indeed present in the air and can contaminate seemingly sterile solutions, however the air itself does not create microbes
Louis Pasteur (1882-1895)
HISTORY OF MICROBIOLOGY:
showed that microorganisms can also be present in non-living matter
Louis pasteur (1882-1895)
HISTORY OF MICROBIOLOGY:
stated that microbial life can be destroyed by heat
Louis Pasteur
HISTORY OF MICROBIOLOGY:
technique to prevent contamination by unwanted microorganism
Aseptic Technique
HISTORY OF MICROBIOLOGY:
found that no matter how long some flasks were boiled, they always produced certain growth-heat resistant bacterial spores
Ferdinand Cohn
HISTORY OF MICROBIOLOGY:
showed that dust carry germs which contaminates sterile broth
John Tyndall (1820-1893)
HISTORY OF MICROBIOLOGY:
formed the concept of tyndallization
John Tyndall
HISTORY OF MICROBIOLOGY:
form of sterilization for three consecutive days
tyndallization
HISTORY OF MICROBIOLOGY:
stated that yeast cells were responsible for the conversion of sugars to alcohol
Theodore Schwann
HISTORY OF MICROBIOLOGY:
basis of the concept pasteurization
Louis Pasteur
HISTORY OF MICROBIOLOGY:
heating beer and wine just enough to kill most of bacteria is an example of a concept of:
pasteurization
HISTORY OF MICROBIOLOGY:
T/F:
Fermentation was not due to microorganisms but due to a chemical instability that converted sugars to alcohol
TRUE
HISTORY OF MICROBIOLOGY:
T/F:
Pasteur described that certain microorganisms known as yeast converts sugar to alcohol in the absence of air (fermentation)
TRUE
HISTORY OF MICROBIOLOGY:
T/F:
Souring and spoilage of wine are caused by different microorganisms called bacteria
TRUE
HISTORY OF MICROBIOLOGY:
Pasteur’s THREE Contribution to Science
: disproved the theory of spontaneous generation
: developed vaccines against anthrax (1881) and rabies (1885)
: improved wine industry through theory of fermentation
HISTORY OF MICROBIOLOGY:
created a porcelain bacterial filter (1884) and developed anthrax vaccine together with Pasteur
Charles Chamberland
HISTORY OF MICROBIOLOGY:
demonstrated that routine handwashing can prevent spread of disease
Ignatz Semmelweis (1816-1865)
HISTORY OF MICROBIOLOGY:
developed the antiseptic system of surgery
Joseph Lister (1827-1912)
HISTORY OF MICROBIOLOGY:
introduced British surgery to handwashing and the use of phenol as antimicrobial agent for surgical wound dressings
Joseph Lister (1827-1912)
HISTORY OF MICROBIOLOGY:
demonstrated the use of phenol for treating surgical wounds and also sprayed phenol over the surgical area
Joseph Lister (1827-1912)
HISTORY OF MICROBIOLOGY:
theory that is based on the concept that microorganisms might cause disease
Germ Theory of Disease
HISTORY OF MICROBIOLOGY:
established the first proof that bacteria causes diseases
Robert Koch (1843-1910)
HISTORY OF MICROBIOLOGY:
discovered Bacillus anthracis, the causative agent of anthrax (1867-1877)
Robert Koch
HISTORY OF MICROBIOLOGY:
discovered Mycobacterium tuberculosis
Robert Koch
HISTORY OF MICROBIOLOGY:
was the first to culture bacteria on boiled potatoes, gelatin and used meat extracts and protein digests for cultivation
Robert Koch
HISTORY OF MICROBIOLOGY:
developed culture media for observing growth of bacteria isolated from human body
Robert Koch
HISTORY OF MICROBIOLOGY:
Koch’s Postulates:
: microorganism must be present in every case of the disease but absent from healthy organisms
: the suspected microorganism must be isolated and grown in pure culture
: same disease must result when the isolated microorganism is inoculated into a healthy host
:same organism must be isolated again from the diseased host
HISTORY OF MICROBIOLOGY:
suggested the use of agar as a solidifying agent
Fannie Eilshemius Hesse
HISTORY OF MICROBIOLOGY:
developed petri dish (plate)
Richard Petri
HISTORY OF MICROBIOLOGY:
developed the enrichment-culture technique and the use of selective media
Martinus Beijenrick and Sergie Winogradsky
HISTORY OF MICROBIOLOGY:
experimented on how people can be protected against small pox

HISTORY OF MICROBIOLOGY:
collected scrapings from cowpox blisters and inoculated a healthy volunteer with cowpox material by scathing the person’s arm with pox-contaminated needle
Edward Jenner
HISTORY OF MICROBIOLOGY:
used the term “vaccine” for cultures of avirulent microorganisms use for preventive inoculation
Louis Pasteur
