Document Summary
Learning objectives (los): microbiology basics/types of microbes. List and briefly describe the different sorts of organisms that are considered to be microbes/microorganisms. Archaea: prokaryotic, cell walls lack peptidoglycan, methanogens (produce methane as a waste from respiration), extreme halophiles (salt loving), extreme thermophiles (live in hot sulfurous waters, not known to cause disease in humans. Protozoa: unicellular eukaryotes, move by pseudopods, flagella or cilia, live as free entities or parasites, absorb or ingest organic compounds from their environment, some are photosynthetic (euglena, can reproduce sexually or asexually. Viruses: acellular, very small (need electron microscope); dna or rna, protein coat (sometimes with a lipid membrane envelope); parasitic of other forms of life. Animal parasites are eukaryotes: two major groups of parasitic worms are flatworms and the round worms called the helminthes, during some stages of their life helminthes are microscopic, describe similarities and differences between different sorts of microorganisms. Bacteria: cell walls contains protein-carbohydrate complex: peptidoglycan.
