Transmissible spongiform encephalopathy

Variant Creutzfeldt-Jakob disease is an infectious and transmittable form of a prion, although extremely rare it still becomes highly fatal if infected. This disease can also be classified as a Transmissible Spongiform Encephalopathy (TSE) that is gained through exposure to the Bovine Spongiform Encephalopathy (BSE) from contaminated cattle or meat. As this is not a prominently spread disease around the world and considering it was only recognised in 1996 it has only held 175 cases in the United Kingdom

TSE: Unique Neuroinvasive Pathogens Overview Transmissible spongiform encephalopathies (TSEs), also referred to as prion diseases, are a range of progressive neurodegenerative diseases that affect various mammals, including humans. These diseases are caused by exposure to prions, infectious agents that result from the misfolded form of a glycoprotein found at the surface of cells: PrPc. The abnormal variant (PrPSc) is highly resistant to heat, chemicals and disinfection procedures such as formalin

different forms of prions: normal PrPC and the pathological isoform, PrPSc. The two forms are chemically similar but shaped, or folded differently. PrPC occurs naturally in most mammals but PrPSc seems to bring with it various diseases, or spongiform encephalopathies. Various forms of these diseases have been found in many animal species, including humans. The actual means by which PrPSc propagates itself remains unknown but scientists believe the modified protein alters the normal protein molecules

in the United States was found in Michigan in 1947 when the flock owner had imported sheep of British origin several years prior. Since then scientists have researched to find the cause of the scrapie agent that are classified as transmissible spongiform encephalopathy. At the present, scientists have presented three main theories that explain why the scrapie agent holds a dangerous threat against its host and how it elicits its symptoms. Scientists are finding genetic alternatives to prevent and

Prion Diseases Abstract Transmissible spongiform encephalopathies (TSEs) are neurodegenerative diseases that are thought to be caused by the misfolding of prion proteins. Prions are able to replicate in the absence of nucleic acids. TSEs include: scrapie, bovine spongiform encephalopathy, Creutzfeldt-Jakob disease, kuru, Gerstmann-Straussler-Scheinker disease, and Fatal Familial Insomnia. They can affect many different animals, including humans. Currently, there are no ways to diagnose, treat

Bovine Spongiform Encephalopathy is more commonly known to humans as Mad Cow Disease or BSE. BSE originated from scrapie or Endemic Spongiform Encephalopathy, which is a disease that has affected mostly sheep and goats. BSE is an illness that attacks the brain and spinal cord of adult cattle due to an infection by a transmissible agent known as a prion. Once affected by BSE cattle began to develop strange behavior such as aggression, lack of coordination with the inability to stand or walk, and abnormal

Most often when people think of proteins, we do not think of them as being harmful or infectious agents. In fact we are generally taught that proteins are essential for organisms to function and to function correctly. However, there are indeed proteins that one could consider to be killer proteins. These proteins are called prions. Prions are a particularly interesting type of protein just in the fact that they have the ability to misfold on their own and also to become infectious agents. In simplest

Cannibalism to say the least is a very "taboo" word. Cannibalism is known to be very disturbing and sets off a certain set of powerful emotions when spoken about. One thing about cannibalism is that it used to be considered a normal part of life, and has only recently been seen as "taboo" in the recent centuries. Many people believe Cannibalism should be legal world-wide, but only have reasoning's of culture and religions. Cannibalism should be illegal because of immorality, diseases , and murder

Twenty years after the wind down of the infamous Mad Cow Disease epidemic and thirty years following its first appearance in British cattle, Bovine Spongiform Encephalopathy continues to impact thousands. In 1996, it was discovered that bovine spongiform encephalopathy could be transmitted to humans in the form of Variant Creutzfeldt-Jakob disease (vCJD), most commonly through the ingestion of beef contaminated with BSE. Of the roughly 229 reported cases of vCJD, it’s believed that at least 3 cases
