  Biosafety



Biosafety

   The application of knowledge, techniques and equipment to prevent personal, laboratory and environmental exposure to potentially infectious agents or biohazards. Biosafety defines the containment conditions under which infectious agents can be safely manipulated. The objective of containment is to confine biohazards and to reduce the potential exposure of the laboratory worker, persons outside of the laboratory, and the environment to potentially infectious agents.

Equipment
Expendable and nonexpendable equipment, supplies, apparatus, and instruments that are used in diagnostic, surgical, therapeutic, scientific, and experimental procedures.

Environment
The sum of the total of the elements, factors and conditions in the surroundings which may have an impact on the development, action or survival of an organism or group of organisms. The environment is as opposed to genetics. We are the product of our genetic inheritance and our environment.



SIMILAR TERMS

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.

Bioscrub
Bioscrub is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): chlorhexidine gluconate.

Biostatistics
Application of statistics to biological and medical problems.

Biosynthetic Human Insulin
A man-made insulin that is very much like human insulin.

Biotechnology
The fusion of biology and technology. Biotechnology is 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. Biotechnology is expected to become increasingly important in the 21st century.

Bioterrorism
"Terrorism using biologic agents. Biological diseases and the agents that might be used for terrorism have been listed by the US Centers for Disease Control and Prevention (the CDC). The list includes a sizable number of ""select agents"" -- potential weapons whose transfer in the scientific and medical communities is regulated to keep them out of unfriendly hands."

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 with prolonged intravenous feeding or the frequent consumption of raw egg whites which contain a biotin antagonist called avidin. Biotin supplementation is recommended during pregnancy because the biotin requirement rises during pregnancy and a substantial number of pregnant women become biotin depleted. Extra biotin is also needed during long-term anticonvulsant treatment which depletes biotin.

Bipolar disease
Manic-depressive disease. See: Bipolar disorder.
