Document Summary
Shape: coccus: spherical shaped form, bacillus: rod shaped form, vibrio: curved rod shaped, pleiomorphic: variable or indistinct, spirilla: coiled shape, spirochete: wavy shaped; have an axial filament (flagella) How they group together: diplo-: pairs, staph(ylo)-: irregular grape-like clusters (more than pairs, strep(to)-: chains, palisades: cells that lie together with their sides parallel, tetrad: clustering of 4 cells together; also called sarcina. Definitions: microbiology: study of microorganisms or microbes, microbes: small organisms visible only with a microscope. Lack a true nucleus with a nuclear membrane. Dna enclosed in a nucleus by nuclear membrane. Lack a cell wall (except for plants & fungi) Natural bacteria becomes uncontrolled in their division; when balances are thrown off. Native bacteria in the body contributes to the immune process of the body. Cell wall: protects & provides shape; contains info to whether the bacteria is gram + or gram - (can identify bacteria & treatment we need to use)
