Document Summary
Immunology- study of protection from foreign macromolecules/ invading microorganisms & our responses. Classes of organisms: viruses/ chlamydia, mycoplasma (grow on nonliving media), bacteria & parasites. Vary in size (small, 1-2 microns), complexity & growth conditions. Bacteria in body- skin, gi tract (not stomach-too acidic) Sterile body parts- cns, urinary tract/ blood (when in body) Viruses- nucleic acids (rna or dna), surrounded by protein shell (capsid), enter living cells & inject nucleic acid so synthetic processes inside cells start making virus (chlamydia- more complex, multiplies in living cells) Bacteria (prokaryotes)- have rigid cell wall, genetic materials organized into circular chromosome, no nucleus (nucleoid), can create own proteins (rna & Dna) (mycoplasmas- no rigid cell wall, more delicate) Eukaryotes- all unicellular & multicellular animals & plants, have nucleus (contains genetic material) Either resident (always in body) or transient (found in specific location) Gi tract- colons inhabited by anaerobes & coliform organisms.
