Risk groups
Microorganisms can be classified in different risk groups and this classification is based on normal conditions in the facility, possible effects on healthy individuals, and culture volumes typical of experimental or diagnostic procedures.
- pathogenicity and lethality,
- virulence or attenuation,
- infection mechanism, infectious dose and transmission paths,
- concentration and scale,
- culture conditions,
- production of non-cellular derivatives, such as toxins and allergens,
- reproduction cycles and survival structures,
- host range
- degree of natural or acquired immunity of the host,
- resistance mechanism or sensitivity to antibiotics and to other specific agents,
- existence of suitable prophylaxis and therapies,
- existence of oncogene sequences,
- virus production by cell lines,
- parasitic properties,
- the clinical relevance or economic impact of the introduction or release into the environment.
