BMS 212 Lecture Notes - Lecture 3: Gram-Positive Bacteria, Ribosomal Rna, Cytosine
Document Summary
Taxonomy: the system for organizing, classifying, and naming organisms. Nomenclature: the system for naming organisms genus species or genus species: generalities on classification, simple criteria, microscopic morphology. Spirilla and spirochetes: spiral-shaped bacteria: spirilla- rigid, twisting structure, flagella on the pole, spirochete- flexible, twisting structure, flagella inside (helps hold shape) Pleomorphic bacteria: contain no cell walls, vary in shape. Archaebacteria: can be cocci, bacilli, pleomorphic, etc. but can also be star-shaped, triangular, cuboidal, etc: macroscopic morphology. As seen on the growth plate: biochemical characteristics - Their ability to utilize or produce certain chemicals; their chemical composition: complex criteria, chemical analysis. Components of the cell wall or membrane: serological analysis. Utilizing antibodies for specific proteins on the cell: phage type. Using viruses or other bacteria to classify because they are specific with which bacteria they attack. Guanine and cytosine composition; genetic probes; rna sequence: genetic and molecular analysis. Only works with bacteria that we can grow to identify.
