Document Summary
Sterilization: the elimination of all viable microbes (including spores) Disinfection: the use of agents to eliminate nearly all pathogens from a non-living surface. Germicides: act by targeting microbial cell envelopes or by denaturing proteins. Antiseptic: an agent that kills or inhibits microbial growth and can be applied to living tissues. Antibiotics: therapeutic drugs that act by interfering with cellular processes (e. g. cell wall and protein synthesis. Antibiotics (from paper disks) diffuse into the agar and the zone of inhibition can be measured to determine antibiotic susceptibility/resistance. To find out if bac is sensitive or resistant, use the table. Tppse start w 14, 19, 20, 21, 11, 22, 11, 15, 15, 18. Autoclave: achieves sterilization; 121 c moist heat and 15psi pressure. Uv radiation: directed at the nucleic acid of the cell causing thymine dimers in the dna.
