Die Chronic Wasting Disease (CWD; englisch chronic wasting disease, deutsch wörtlich Chronische Auszehrungskrankheit) ist eine ansteckende Erkrankung des zentralen Nervensystems bei Hirschen, die zu den spongiformen Enzephalopathien gerechnet wird. The DNR is working to limit its spread. Wie bei den anderen transmissiblen spongiformen Enzephalopathien handelt es sich beim Erreger vermutlich um ein abnorm gefaltetes Prion, das allerdings bisher nicht isoliert werden konnte. Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. Die Prävalenz kann in befallenen Herden in Gefangenschaft bis zu 100 % betragen; in freier Wildbahn werden Prävalenzen von unter einem bis über 30 Prozent gefunden. JACKSON, Miss. S. L. Benestad, G.

Die Chronic Wasting Disease wurde erstmals in den späten 1960er Jahren in einer Herde von Maultierhirschen in Colorado als Syndrom beschrieben. Prions are unconventional pathogenic agents that are comprised mostly, if not entirely, of an abnormal, infectious form of a normally occurring host protein called a prion protein. Als Vorsichtsmaßnahmen werden empfohlen, in den Enzootiegebieten keine offensichtlich kranken Tiere zum Verzehr zu schießen, beim Ausweiden Latexhandschuhe zu tragen, Kontakt mit Nerven- und Lymphgewebe zu vermeiden, alle zum Zerlegen der Beute verwendeten Messer und anderen Geräte in 50 % Javelwasser zu desinfizieren und das Tier auf CWD testen zu lassen. This application provides an easy-to-use interface for conducting weighted surveillance for chronic wasting disease (CWD) in white-tailed deer populations. When disease-associated prions contact normal prions, they cause them to refold into their own abnormal shape. Some of these collaborative efforts include, but are not limited to: Research performed at the NWHC has been instrumental in developing surveillance strategies for early detection of CWD in Montana (Montana Fish, Wildlife and Parks Department) and Shenandoah National Park (National Park Service), identifying potential disease risks posed by CWD to noncervid species such as bighorn sheep, and identifying environmental factors, like soil and plants, that may facilitate CWD transmission on the landscape.
