Document Summary
Of some cells: differentiation, communication, genetic exchange, motility. Three domains are: bacteria (prokaryotic, archaea (prokaryotic, eukarya (eukaryotic) Three groups we can see without a microscope: animals, fungi, plants. Archaea and bacteria are not closely related. Archaea are closely related to eukarya then bacteria. Eukaryotic microorganisms were the ancestors of multicellular organisms. From the last universal common ancestor ( luca) evolution proceeded to for two domains: archaea, bacteria. Archaea later diverged to form two domains: archaea, eukarya. Robert hooke 1665 was the first book devoted to microscopic observations. Van leeuwenhoek- 1676 first to see bacteria. Ferdinand cohn -1850 first to see bacterial endospores. Louis pasteur- 1864 disproved spontaneous generation theory: designed and successfully used vaccines for rabies anthrax and chicken cholera, 1885 administered rabies vaccine to a boy bitten by a rabid down. The suspected pathogen must be present in all cases of the disease and absent from healthy animals. The suspected pathogen must be grown in pure culture.
