Redi described and drew illustrations of over one hundred parasites, including ticks, nasal flies, and the sheep liver fluke. Sometimes, this bacteria is called the "Weizmann organism" after the name of Chaim Weizmann. 1. Those organisms are: Mycobacterium leprae and Treponema pallidum: They cannot be grown in vitro; however can be maintained in animals.

Hooke's 1665 book, Micrographia, contained descriptions of plant cells. His work made it more clear that diseases occur at the cellular level. The term microbe was first used by Sedillot (1878). The relative simplicity of the microorganism, their short life span and the genetic homogeneity provided an authentic simulated model to understand the physiological, biochemical and genetical intricacies of the living organisms. 98, pp. A Brief History of Microbiology - A Brief History of Microbiology He developed a scientific experiment to test the spontaneous creation of maggots from fresh meats using two jars (one of the jars was left open while the other was closed). No doubt Redis father helped him get the job: six years earlier, in 1642, he himself had been appointed physician to the Medici court.
