Transmissible spongiform encephalopathy

Despite some speculation of scientific findings in regards to prion conversion, research continues. The prion disease, unlike other infectious diseases such as viruses or bacteria, cannot be diagnosed using PCR, cell culture assays, or serology attributable to lack of nucleic acids, which are not recognized by normal host immune responses. Also, owing to uneven distribution throughout the body, finding a tool that can be used on the central nervous system may be easier said than done (25). The

Animal cruelty continues to plague the meat and dairy industry and a policy to reverse this is enacting stricter regulations on meat and dairy labels that explicitly state the additives and preservatives used on the product. Moreover, my policy will persuade people to purchase meat and dairy that is ethically raised and is not made with preservatives or additives, this is my value of health. Moreover, my policy is for those who eat meat and dairy and are unaware of the health side affects of consuming

The word BSE is short but it stands for a disease with a long name, bovine spongiform encephalopathy. "Bovine" means that the disease affects cows, "spongiform" refers to the way the brain from a sick cow looks spongy under a microscope, and "encephalopathy" indicates that it is a disease of the brain. BSE is a progressive neurologic disease of cows. Research shows that the first probable cases of BSE in cows occurred during the 1970 's with two cases of BSE being identified in 1986. BSE possibly

Kuru is an infectious disease that attacks the central and peripheral nervous system. The pathogen itself is a prion protein, which is found commonly throughout the body and is usually anchored to the cell membrane of cells, with the highest concentration in the nervous system. These proteins are made from amino acids and are coiled into certain structures depending on their job. These harmless proteins only become a problem when they change their structure, whether by infection or mutation, and

The first new human prion is discovered in almost 50 years. Prions are misfolded proteins that make copies of themselves by inducing others to misfold, they multiply and cause disease. The resulting illness is MSA, a neurodegenerative disease similar to Parkinson's. An experiment shows that: the mice injected with these samples all developed disease within 3.5 to 5 months. Mice with two copies develop disease spontaneously, after about 10 months, but mice with one copy remain healthy. Injecting either

Pseudorabies Pseudorabies is also called the aujeszky’s disease or in cattle and sheep it’s called the mad itch. It is a contagious viral disease that mainly affects pigs and wild animals. Pigs are capable of carrying the disease without anybody knowing. Pseudorabies virus belongs to the family herpesviridae and is a double-stranded DNA virus. It is usually spread by direct contact with an infected animal. Ingestion of infected meat or carcasses is linked to pseudorabies virus transmission in

Causes for Creutzfeldt-Jakob disease involve abnormal infectious protein in the brain called prion. Proteins are molecules that help the cells in the body to function. These proteins fold into a 3-Dimensional shape (protein folding) that enables them to perform useful functions inside cells in the body. Prions are misfolded prion proteins that begin to build up in the brain causing others to misfold as well. This process causes brain cells to die which then release more prions to other cells of the

discusses the challenges leadership are faced with regarding their corporation and their employees. The challenge this corporation is faced involves the beef contamination of bovine spongiform encephalopathy (mad cow disease). “On December 23, 2011, the U.S. Department of Agriculture has announced that bovine spongiform encephalopathy had been discovered in a Holstein cow in Washington State” (O’Sullivan, 2004). This outbreak caused a global reaction from the eight countries and the meat processing plants

becomes toxic, major changes in the conformation occur as the alpha helix becomes beta pleated sheets. The sheets now expose the hydrophobic amino acid and aggregation, or clumping together of sheets occurs (Borges, 2014). In bovine spongiform encephalopathy (BSE), the disease is caused by the misfolding of proteins that cause proteins and peptides to develop a fibrillary structure. The PrPc is a correctly folded prion and the misfolded form is called PrPSc. BSE occurs when the normal PrPc

system of an animal and a human. The disease infested brain of the animal or human is slowly, progressively, and severely damaged. It has been categorized as a disease, which falls into the category of a disease known as Spongiform Encephalopathy. Having Bovine Spongiform Encephalopathy is an over-dramatized way of specifying that one has diseased brain tissue which is; spongy, porous, and no
