Microbiology |
|
|
They suggested that diseases weres caused by invisible living creatures. |
Lucretius Girolamo Fracastoro |
|
|
He made the earliest observation on bees and weevio using a microcope supposedly supplied by Galileo |
Francesco Stelluti |
|
|
First true microbiologist |
Anton van leeuwenhoek |
|
|
Father of bacteriology and protozoology |
Anton van leewenhoek |
|
|
Anton van leewenhoek created his own single lens microscope. What is the magnification of his microscope? |
50x to 300x |
|
|
It states that life arises from non living matters |
Spontaneous Generation |
|
|
According to him, simple invertebrates could arise from spontaneous generation |
Aristotle |
|
|
The results of his investigation invalidated the long heled belief that life forms could could arise from non living things. (maggots does not rise in decaying meat) |
Francesco Redi |
|
|
He asserted that organic matter possessed a vital force that could give rise to life. |
John Needham |
|
|
He improved Needham's experiments by heating broth placed in a sealed jar There is no growth took place as long as the flask remained sealed Concluded that microorganisms from the air probably had entered Needham's solutions after they are boiled |
Lazzaro Spallanzani |
|
|
It states that living cells can only arise only from pre-existing living cells |
Biogenesis |
|
|
He challenged the doctrine of spontaneous generation with the concept of biogenesis |
Rudolf Virchow |
|
|
He observed that no growth occured in the flask that contained a nutrient solution after allowing the air to pass through a heated tube. |
Theodor Schwann |
|
|
They noticed that no growth occured after allowing the air to pass through a sterile cotton wool placed on a flask of heat sterilized medium |
Heinrich Schroder Theodore von Dusch |
|
|
He disapproved doctrine of spontaneous generation. Air does not generate the microbes itself it only contaminates the sterile solution Microorganisms does not originate from mystical forces present in non living materials |
Louis Pasteur |
|
|
He showed that dusts carry germs that could contaminate a sterile broth |
John Tyndall |
|
|
It is a form of sterilization in the 19th century that uses moist heat for 3 consecutive days ro eradicate vegetative cells and endospores. |
Tyndallization |
|
|
He discovered that there are bacteria that could withstand a series of heating and boiling because of heat resistant structure called endospores |
Ferdinand Cohn |
|
|
He showed the importance of oxygen to life |
Antoine- Laurent Lavoisier |
|
|
He stated that yeast is responsible for the conversion of sugars to alcohol |
Theodor Schwann |
|
|
He developed anthrax and rabies vaccine |
Louis Pasteur |
|
|
Accorisng to him, yeasts convert sugar to alcohol in the absence of air (fermentation) |
Louis Pasteur |
|
|
He proposed the use of heat in killing microorganisms and now called aseptic technique |
Louis Pasteur |
|
|
He proved that in the presence of air, bacteria converts the alcohol in the beverage to vinegar or acetic acid. |
Louis Pasteur |
|
|
He suggested that minimal heating level of beers and wines that is sufficient to kill most of the bacteria (pasteurization) |
Louis Pasteur |
|
|
He demonstrated that routine handswashing can prevent the spread of disease |
Ignaz Semmelweis |
|
|
He introduced the system if antiseptic surgery in Britain |
Joseph lister |
|
|
It is based on the concept that microorganisms can cause diseases |
Germ theory of disease |
|
|
He discovered Bacillus anthracis and Mycobacterium tuberculosis |
Robert Koch |
|
|
He developed a culture media for observing bacterial growth isolated from the human body. |
Robert Koch |
|
|
What is the koch postulates? |
1. The microorganisms must be present in every case of the disease but absent from a healthy host. 2. The suspected microorganisms must be isolated from a diseased host and growth in a pure culture. 3. The same disease must be present when the isolated microorganisms is inoculated into a healthy host. 4. The same organism kust be isolated again from the diseased host. |
