Pioneers in the history of microbiology Flashcards
He suggested that disease was caused by “invisible living creatures”
Girolamo Fracastoro
He is the one of the early microscopists whose self-made single lens microscope enabled the study of microorganisms, leading him to the discovery of bacteria, free-living and parasitic miscroscopic protist, sperm cells, blood cells, parasites and fungi.
The father of Bacteriology and Protozoology, Anton van Leeuwenhoek
Another term for microorganisms
Minute organisms
He disouted the Theory of Spontaneous Generation and believed that fly maggots did not arise spontaneously from decaying meat if the meat was covered to prevent the entry of insects
Francesco Redi
He believed that organic matter possesses a unique force that brings forth life. He also showed that tightly-covered boiled meat broth became cloudy due to microbial contamination.
John Needham
He improved Needham’s experiment by controlling the entry of air in the flask set-up and observed that no microbial growth is suggestive of air as a possible source of contamination
Lazzaro Spallanzani
He developed the principles of vaccination, microbial fermentation, and pasteurization. He also proves that yeasts are useful in converting sugar into alcohol (wine) in the absence of air (fermentation) but if done wrong, vinegar is produced instead, caused by the presence of bacteria which causes the souring of wine and dairy products.
Louis Pasteur
A British surgeon and pioneer of antiseptic surgery who introduces the use of carbolic acid (phenol) as a chemical sterilizing agent for surgical instruments
Joseph Lister
He is credited for the Gram-staining technique used to distinguish two major groups of bacteria: Gram positive (+) and Gram negative (-)
Hans Christian Gram
He discovered the powerful anti-biotic, bezylpenicillin (Penicillin G) from mold, Penicillium notatum
Alexander Fleming
He established the theory that etiologic agents cause diseases. He also discovered the agents, Bacillus antracis (anthrax), Mycobacterium tuberculosis (TB), and Vibrio cholera (cholera)
Robert Koch
