Chronic Wasting Disease and Potential Transmission to Humans
نویسندگان
چکیده
Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Increasing spread of CWD has raised concerns about the potential for increasing human exposure to the CWD agent. The foodborne transmission of bovine spongiform encephalopathy to humans indicates that the species barrier may not completely protect humans from animal prion diseases. Conversion of human prion protein by CWD-associated prions has been demonstrated in an in vitro cell-free experiment, but limited investigations have not identified strong evidence for CWD transmission to humans. More epidemiologic and laboratory studies are needed to monitor the possibility of such transmissions

Chronic wasting disease.
Chronic wasting disease (CWD) is the only known prion disease affecting free-ranging animals and has become a serious epidemic in North America. Although any case was reported from Europe, the spread of the disease to other continents and regions cannot be excluded, because the transmission of CWD is the most efficient among prion diseases. This article reviews the host range of CWD including e...
متن کاملChronic wasting disease: Emerging prions and their potential risk
Prions cause fatal neurodegenerative diseases in humans and animals by converting the cellular prion protein PrP into aggregation-prone PrP. Chronic wasting disease (CWD) is a prion disease or transmissible spongiform encephalopathy (TSE) of free-ranging and farmed cervids. CWD is highly contagious and transmitted through horizontal transmission enabled by the shedding of prions in excreta and ...
متن کاملChronic wasting disease in deer and elk: scientific facts and findings.
Chronic wasting disease (CWD) is a prion disease of cervids such as deer and elk in North America. Unlike other transmissible spongiform encephalopathy (TSE) such as scrapie, CWD occurs in both captive and wild ranging animals, but not in domestic ruminants such as sheep and cattle. In this paper, the history of the disease, pathogenesis of CWD, susceptibility of animals, its transmission mecha...
متن کاملHuman prion protein sequence elements impede cross-species chronic wasting disease transmission.
Chronic wasting disease (CWD) is a fatal prion disease of North American deer and elk and poses an unclear risk for transmission to humans. Human exposure to CWD occurs through hunting activities and consumption of venison from prion-infected animals. Although the amino acid residues of the prion protein (PrP) that prevent or permit human CWD infection are unknown, NMR-based structural studies ...
متن کاملPrions in skeletal muscles of deer with chronic wasting disease.
The emergence of chronic wasting disease (CWD) in deer and elk in an increasingly wide geographic area, as well as the interspecies transmission of bovine spongiform encephalopathy to humans in the form of variant Creutzfeldt Jakob disease, have raised concerns about the zoonotic potential of CWD. Because meat consumption is the most likely means of exposure, it is important to determine whethe...
