Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep. [2]
Found in deer in northern Colorado and southern Wyoming in the 1990s, chronic wasting disease (CWD) has been recorded in free-ranging deer, elk and moose in at least 32 states across all parts of ...
TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
Due to small differences in PrP between different species it is unusual for a prion disease to transmit from one species to another. The human prion disease variant Creutzfeldt–Jakob disease, however, is thought to be caused by a prion that typically infects cattle, causing bovine spongiform encephalopathy and is transmitted through infected ...
Aug. 1—Washington has its first case of chronic wasting disease. The Washington Department of Fish and Wildlife announced Thursday that it confirmed the state's first case of the always-fatal ...
The importance of ecopharmacovigilance is to monitor adverse effects of pharmaceuticals on humans through environmental exposure. [citation needed] Due to this relatively new field of science, researchers are continuously developing and understanding the impacts of pharmaceuticals in the environment and its risk on human and animal exposure ...
An opportunistic disease requires impairment of host defenses, which may occur as a result of genetic defects (such as chronic granulomatous disease), exposure to antimicrobial drugs or immunosuppressive chemicals (as might occur following poisoning or cancer chemotherapy), exposure to ionizing radiation, or as a result of an infectious disease ...
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
