Document Summary

Fly larvae can only develop in meat that fly can reach. Boiled broth in flask, curved neck of flask so air can enter but no dust, no microorganisms appeared. Supernatural forces, poisonous vapors, imbalances between the four humors. Showed microorganism (fungus) can cause disease in silkworms. Sterilized instruments with heat, phenol to prevent infections. First attenuated vaccine from pure culture of pathogen attenuated. Humoral immunity, antibodies produced in blood against toxin to be protective against infection. Cellular immunity, phagocytes engulfing disease-causing bacteria and provide immunological protection. Oxidation of iron, sulfur, ammonia by soil bacteria for energy, transformation of carbon dioxide to organic matter. Artificial classification of organisms, based on visible similarities. Natural classification of organisms, reflects evolutionary relatedness between organisms. Bacteria, archaea, eukaryotes equally distant, used 16s ribosomal rna gene. Primitive eukaryotic cell engulfed an ancient prokaryote to create the first eukaryotic cell. Stability, predictability, build larger groups, study a member, learn about the group.
