Facultative Anaerobe - ability to grow in aerobic and anaerobic
Opportunistic infection: caused by bacteria which are usually harmless but cause disease under certain conditions
Sterilization - destroys all forms of microbial life Disinfection - eliminates many pathogenic microorganisms EXCEPT BACTERIAL SPORES (dormant structures produced by bacteria which are heat resistant) Decontamination - removes pathogens from objects so they are safe to use
Bactericidal - kills bacteria Bacteriostatic - inhibits bacteria from growing
Antiseptics - used on living tissue Disinfectant - used of non living
Good microbial agent = antibacterial but not cytotoxic to host cell
small infectious obligate intracellular parasite Virus particle - virion
Taxonomy - classification of viruses. Group based on mode of transmission or structures.
HIV - diploid genome Adenovirus - no envelope
Virulence - capacity of virus to cause disease.
Viranaemia - presence of virus in blood
