Document Summary
Depend on the host cell for replication and metabolism and biosynthetic products that they need such as nucleic acid and amino acid. Hepatitis c virus, coronavirus, herpes virus, bird flu (pig can be the host), smallpox virus, influenza. Mushroom is the sexual organ-macroscopic but it has microscopic. *******disproved the theory of spontaneous generation- non-living objects can give rise to living organisms. He used "swan-necked" flask-allowed air to enter but not the microbes. Conclude: microbes are in the air, there is no "life force" Staining methods-able to see microbes that without pigment. Used solid growth media (agar)-purify microbes from mixture. Able to identify bacteria which caused tuberculosis, cholera, anthrax. Discovered spores-explain survival of anthrax for long periods in soil. Be found in all cases of the disease. Be isolated from the diseased host in pure culture. Limitation: can"t grow all microbes in the lab. Discovered mould growing in petri dish killed staphylococcus.
