1. 3'-azido-3'-deoxythymidine (AZT)
An antibiotic used to treat infection by HIV (the AIDS virus ). The drug works by blocking replication of the HIV genetic material (in this case it is composed of RNA rather than DNA ) by preventing the viral RNA from inserting into the host DNA.
2. Acquired immunodeficiency syndrome (AIDS)
A collection of disorders that develop as a result of infection by the human immunodeficiency virus (HIV) , which attacks helper T cells , crippling the immune system and greatly reducing the body's ability to fight infection; results in premature death brought about by various diseases that overwhelm the compromised immune system.
3. Acycloguanosine (acyclovir)
An antiviral medication used to treat herpesvirus infections; it works by inhibiting viral DNA synthesis.
An icosahedral (20-sided) virus that contains DNA (as opposed to RNA ); there are over 40 different adenovirus varieties, some of which cause the common cold.
* In chemistry, refers to the accumulation of molecules of a gas or liquid on the surface of another substance; note that the accumulating molecules do not actually penetrate the substance they're on. * In virology, refers to the adhesion of a substance to an organic particle in a solution, e.g. the adhesion of a virus to a cell. Compare absorption .
6. African green monkey kidney cells
Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain virus es like poliovirus.
A method of using the t-DNA of plasmid s to infecting plant cells with DNA from a plant virus .
8. AIDS (acquired immunodeficiency syndrome, HIV, human immunodeficiency virus)
Acronym for Acquired Immunodeficiency Syndrome. An epidemic disease caused by an infection by human immunodeficiency virus (HIV-1), a retrovirus that causes immune system failure and debilitation and is often accompanied by cancers such as Kaposi's sarcoma as well as secondary infections such as tuberculosis . AIDS is spread through direct contact with bodily fluids.
9. AIDS-related complex (ARC)
A set of symptoms, such as lymph node enlargement, fever, loss of weight, diarrhea, and minor opportunistic diseases associated with a weakened immune system, which indicates a less severe form of infection by the HIV virus than AIDS itself. In some cases this is diagnosed as a precursor to AIDS. Also known as "AIDS-related condition" or "AIDS-related syndrome".
10. Alpha viruses
These are the major virus es in the Togavirus group and include eastern and western equine encephalitis viruses, the Sindbis virus and the Semliki Forest virus. The last two viruses are being researched as vector s for expressing heterologous gene s.
