Biosafety level: A specific combination of work practices, safety equipment, and facilities which are designed to minimize the exposure of workers and the environment to infectious agents.
The biosafety levels are:
Level 1 — This level applies to agents that do not ordinarily cause human disease.
Level 2 — This level is appropriate for agents that can cause human disease, but whose potential for transmission is limited.
Level 3 — This level applies to agents that may be transmitted by the respiratory route which can cause serious infection.
Level 4 — This level is used for the diagnosis of exotic agents that pose a high risk of life-threatening disease, which may be transmitted by the aerosol route and for which there is no vaccine or therapy.
Biotechnology: The fusion of biology and technology, the application of biological techniques to product research and development. In particular, biotechnology involves the use by industry of recombinant DNA, cell fusion, and new bioprocessing techniques to produce large molecules useful in treating and preventing disease. Slang biotech.
Terrorism using biologic agents that are harmful to humans. Biological diseases and the agents that might be used for terrorism have been listed by the US Centers for Disease Control and Prevention (CDC). These agents include viruses, bacteria, rickettsiae (microorganisms that have traits common to both bacterial and viruses), fungi, and biological toxins. The biologica […]
Biotherapy: Treatment to stimulate or restore the ability of the immune (defense) system to fight infection and disease. Biological therapy is thus any form of treatment that uses the body’s natural abilities that constitute the immune system to fight infection and disease or to protect the body from some of the side effects of treatment. […]
Biotin: A water-soluble B-complex vitamin involved in carbon dioxide transfer and therefore essential to the metabolism of carbohydrate and fat. A balanced diet usually contains enough biotin. Foods with high biotin levels include nuts, cereals, green leafy vegetables and milk. Biotin deficiency, which is characterized by hair loss and a scaly red rash, can occur […]
