BSL-2
BSL-2 Biosafety level 2. A level of biosafety considered appropriate for agents that can cause human disease, but whose potential for transmission is limited.
RELATED TERMS--------------------------------------
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.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
SIMILAR TERMS--------------------------------------
BSL-1
Biosafety level 1. The lowest level of biosafety, a level that applies to agents that do not ordinarily cause human disease.
BSL-3
Biosafety level 3. A level of biosafety considered appropriate for agents that may be transmitted by the respiratory route which can cause serious infection.
BSL-4
Biosafety level 4. The highest level of biosafety. This level is used for the diagnosis of exotic agents such as the Ebola virus 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.
PREVIOUS AND NEXT TERMS--------------------------------------
Brunhilde virus
Type 1 poliovirus. Named after a female chimpanzee from which it was first isolated. There are two other strains of poliovirus: Type 2 (known as the Lansing virus) and Type 3 (known as the Leon virus). Immunity to one strain does not provide protection against the other two. All three strains are therefore included in the poliovirus vaccine.
Bruton agammaglobulinemia tyrosine kinase
A genetic type of immunodeficiency characterized by failure to produce mature B lymphocytes and gamma globulin, due to mutation (change) in the agammaglobulinemia tyrosine kinase gene situated on the X chromosome (in the region Xq21.3-q22). The disorder is inherited as an X-linked recessive trait.
