Document Summary

Lecture one: micro = small, bio = life, logy = study (of) or science. (i. e. (cid:374)ot (cid:862)ger(cid:373)s(cid:863), (cid:862)(cid:271)ugs(cid:863): what are they made of, viruses: - nu(cid:272)lei(cid:272) a(cid:272)id (cid:894)either rna or dna (cid:374)e(cid:448)er (cid:271)oth! (cid:895) Attach, inject nucleic acid (penetration), highjack synthetic processes inside cells to make more viruses, package, get out while going is good : viruses are not self-sufficient, bacteria: - rigid cell wall to keep things in place. Some bacteria do not have a rigid cell wall and are more fragile (i. e. , mycoplasmas) Biotechnology, spoilage of foods, bioremediation, functional foods, etc. Brian, heart etc. ph environment: most can only stay in your body for a short time, eukaryotes: - unicellular and multicellular animals and plants. Infectious disease and the human (immune) response: microbial disease. Interaction between microorganisms and the host (us) is continuous battle. High pathogenicity but low virulence: you have a high chance to get sick but only for a short time e. g. chickenpox.
