Louis pasteur first to connect cause and effect (microorganisms are responsible for disease, growth, metabolic processes. Broth did not become contaminated without contact with the end of the flask. The suspected pathogen must be present in all cases of the disease and absent in healthy animals. The suspected pathogen must be grown in pure culture. Cells from a pure culture of the suspected pathogen must cause disease in a healthy animal. The suspected pathogen must be reisolated and shown to be the same as the original. Some animals may be carriers (appear healthy, but carry the pathogen) Some pathogens are not culturable (obligate intracellular pathogens) Each organism has two names: genus and species. Prokaryotes are generally smaller in size than prokaryotes. Model system of complex prokaryotic life cycle - regulation of cell cycle = important. Chloroflexus (ancient, photosynthetic but does not produce oxygen) Arthrobacter undergoes morphogenesis from rod to coccus during growth. Fatty acids + glycerol + phosphate + ethanolamine.
