Document Summary

Immunology = study of our protection from foreign macromolecules or invading organisms and our responses to them. Viruses / chlamydia (grow only in living cells) Small (microscopic): 1-2 microns (1 mm = 1000 microns); proper name (not germs bugs ) Nucleic acid (either rna or dna never both) Attach, inject nucleic acid (penetration), highjack synthetic processes inside cells to make more viruses, package, get out while going is good Rigid cell wall to keep things in place. Some bacteria do not have a rigid cell wall and are more fragile (i. e. mycoplasmas) Genetic material is organized into a nucleus. Gi-tract: colon is inhabited by anaerobes and coliforms. Transient as a result of displacement of resident flora, injury or trauma, human behaviors. No bacteria: central nervous system, respiratory system, blood, sub-cleaning system. Complement (a complex system of plasma proteins that work together to resist bacterial infection) How do the bad guys get in.
