Variant Creutzfeldt-Jakob disease (vCJD)

A human disease thought due to the same infectious agent as bovine spongiform encephalopathy (BSE), or mad cow disease. Both the human and bovine disorders are invariably fatal brain diseases with unusually long incubation periods measured in years, and are caused by an unconventional transmissible agent, a prion, resulting in the deposition of amyloid tissue that causes a breakdown of brain tissue leaving the infected brain with a "spongy" ("spongiform") appearance. The disease in humans is sometimes called new variant Creutzfeldt-Jakob disease (nvCJD).

West Nile virus (WNV)

The mosquito-borne virus that causes West Nile fever. One of the flaviviruses, a family of viruses also responsible for dengue, yellow fever, and tick-borne encephalitis virus. Like the other flaviviruses, the West Nile virus is a positive-strand RNA virus containing three structural proteins and a host-derived lipid bilayer. The West Nile virus is an icosahedral structure of about 500 angstroms in diameter. The overall structure of the West Nile virus most closely resembles that of dengue fever virus but the surface proteins are slightly different, which may give West Nile virus some of its unique features.

White blood cell (WBC)

Blood cell that fights infection, also called leukocyte. White blood cells are protective cells in the bloodstream. They attack bacteria by squeezing through capillary walls to reach the area of infection. The major portion of the buffy coat is composed of white blood cells.

Whole blood (WB)
