Document Summary

Hss1100 lecture #1 general principles of microbiology. 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 (1mm = 1000 microns, address them by their proper names, correct way to address these germs (underline the whole work for marks, listeria monocytogens, species, listeriae, listeriosis. Viruses: nucleic acid (either rna or dna . Never both!: surrounded by protein shell (capsid, attach, inject nucleic acid (penetration), highjack synthetic processes inside cells to make more viruses, package, get out while going is good. Bacteria: rigid cell wall to keep things in place, genetic material circular chromosome, no nucleus (nucleoid, both dna and rna, binary fission. ** some bacteria do not have a rigid cell wall and are more fragile (ex. Eukaryotes: unicellular and multicellular animals and plants, genetic material is organized into a nucleus.
