Check out our quiz-page with tests about: Explorable.com (Jan 13, 2010). Two men are credited today with the discovery of microorganisms using primitive microscopes: Robert Hooke who described the fruiting structures of molds in 1665 and Antoni van Leeuwenhoek who is credited with the discovery of bacteria in 1676. Six years later in 1654, he returned to Delft to establish his own draper business and got married. He soon established good reputation with the Royal society through his deep analysis and careful observations. No problem, save it as a course and come back to it later.

Van Leeuwenhoek discovered "protozoa" - the single-celled organisms and he called them "animalcules". With the passage of time, he got keenly interested in glass processing and lens grinding. Spontaneous generation of bacteria and other organisms was thought to be the driving process of putrefaction. This represents a strikingly different etiology of deaths and it will be interesting to see how these trends continue to change.Â. This project has received funding from the. Fleming also discovered very early that bacteria developed antibiotic resistance whenever too little penicillin was used or when it was used for too short a period.

Sir Alexander Fleming, a Scottish biologist, defined new horizons for modern antibiotics with his discoveries of enzyme lysozyme (1921) and the antibiotic substance penicillin (1928). Despite some went unacknowledged, knowing how many lives saved from their discovery should be a sign of gratitude to their great discovery. He also studied physical structure of ivory and discovered parasites in flea using more powerful microscopes. The species name, madseniana, reflects the legacy of Madsen’s work in the field of environmental microbiology. He also improved the microscope and laid foundation for microbiology. The bacteria disappeared. He is often cited as the first microbiologist to study muscle fibers, bacteria, spermatozoa and blood flow in capillaries. In Micrographia (1665), Hooke presented the first published depiction of a microganism, the microfungus Mucor. Three weeks later, on April 10, he published an article entitled "The Etiology of Tuberculosis" (1).

He experimented to calculate the number of microorganisms in water and examined other objects like skin, hair and blood. This, however, was debunked by Louis Pasteur whose research on sterilization clearly indicated that this was not the case. With his superior light adjusting techniques, he was able to make microscopes which could magnify over 200 times and to some he even had microscopes magnifying up to 500 times.
