Wasting disease

Chronic Wasting Disease (CWD) is a fatal neurodegenerative transmissible spongiform encephalopathy (TSE ) found in some white tailed deer. CWD is associated with diseases such as Mad-Cow disease, Scrapie, and Creutzfeldt–Jakob disease. With well supported evidence it is hypothesized that CWD originated from Scrapie. The causation of CWD is an abnormal form of PrPcwd prion. This prion is a naturally occurring protein found in mammals. Prions lack genome and are highly resistant to degradation. Chronic

In the early stages of infection, animals do not show any symptoms of Chronic Wasting Disease (Rembert, 2014). In fact, most deer with Chronic Wasting Disease do not appear to be sick (Rembert, 2014). The incubation period can range from one to five years (Rembert, 2014). In later stages, infected animals begin to display abnormal behavior such as staggering, carrying their heads and ears lower, drooling, not showing fear of humans, and an exaggerated wide posture (Rembert, 2014). Sick animals may

million deer in the United States (Rooney, 2012). Although with these over-abundant populations comes the destruction of natural resources along with diseases and other factors that can tremendously affect the population. While there are many factors that play an active role in the declination of Whitetail deer populations, chronic wasting disease is just one of them. Densities Predators, hunters, and habitat contribute to the increasing densities of whitetail deer in some locations. The populations

Chronic wasting disease has been around for more than 60 years and has been destroying the deer and elk population in 23 US states. It is shutting down hunting in some states in United States and limiting it in other states. The Department of Natural Resources needs to the help the deer and elk population out by shutting down feeding and hunting. Chronic wasting disease is a transmissible spongiform encephalopathy of mule deer, white tailed deer, and moose. In 1967 chronic wasting disease was discovered

cases of Chronic Wasting Disease have increased to over 25% in bucks and over 10% in does (Marien). With CWD being such a deadly disease, the rising percentage of cases has led to decreasing deer populations. Because the spread of CWD has resulted in many deaths, fewer hunting tags are allowed in affected areas to help the deer herd get healthy again. It is possible, though, that as the populations grow back, CWD may also become more prevalent. Actually stopping this tragic disease is a challenge,

Can you imagine the impact of an always fatal disease on a population? Chronic Wasting Disease, or CWD for short is a prime example in the whitetail deer herd. CWD is a fatal neurological disease known as a type of transmissible spongiform encephalopathies (TSEs). In deer this disease causes a characteristic spongy degeneration of the brains of infected animals, resulting in emaciation, excessive drinking and urination, abnormal behavior, loss of bodily functions, and death (Witkowski 3). As a result

urchins and sand dollars? Did you guess it’s a starfish, also known as a sea star? Wasting syndrome disease What is wasting syndrome disease? No one knows for sure where Wasting syndrome disease came from, but when sea stars get it they curl and shrivel up causing them to turn into mush. Also it hurts the food chain because if animals eat starfish with the disease it will harm them causing them to die. This disease is happening from coast of Alaska to the coast of Mexico. Life as a starfish

Chronic Wasting Disease (CWD) is a brain disease in deer related animals that produces small lesions in the brains of diseased animals (CWD-Info 2013). Lesions are an area of severe tissue change in the brain (CWD-Info 2013). The lesions can range from harmless to very serious cases (CWD-Info 2013). Infectious parts of CWD are neither bacteria or viruses, but are thought as prions (CWD-Info 2013). Prions are dangerous proteins without nucleic acids (CWD-Info 2013). The prions break down the tissue

from a mysterious wasting syndrome. Similar die-offs have occurred before in the 1970s, 80s, and the 90s, but never before at this magnitude and over such a wide geographic area. Pisaster ochraceus and many other species of sea stars have been affected by the current sea star wasting syndrome event. The following paper by Hewson et al. “Densovirus associated with sea-star wasting disease and mass mortality” provides evidence for a link between a densovirus (SSaDV) and sea star wasting syndrome (SSWS)

needed resources. Wasted food is a strong loss as a result of wasted water, money and food for others in need. Moreover, food is a considerable loss considering it results in wasted water. In the article titled, “When You Waste Food, You're Wasting Tons Of Water, Too”, it says, “According to the World Resources Institute, an environmental think tank, inside the 1.3 billion tons of food wasted every year worldwide is 45 trillion gallons of water.” Another article titled, “Wasted Food=Wasted Water”
