Bovine brucellosis, which is caused by Brucella abortus, is a global zoonotic disease that primarily affects livestock (Rhyan, et al. 2013). The highly contagious bacterial disease can be found in both humans and animals. In humans, brucellosis can cause night sweats, recurrent fever, back and joint pain, arthritis, and other influenza like symptoms (Rhyan, et al. 2013). In livestock, it is known to cause abortions, arthritis, male reproductive tract lesions, retained placentas, and bursitis (Rhyan, et al. 2013). Many bison carry antibodies to the virus. The active virus is present in only the reproductive tract of pregnant females (Lavigne, 2002). The most common route of transmission is oral. Bison and elk, like most ungulates, lick…
Hunting is often portrayed purely as a form of sport or the quest for a big trophy. But what most people do not acknowledge is that it does much more for the human population in general. Hunting provides us with the resources that allow us to live comfortably. Not only does it do this, but it provides health to our environment as well as our economy. Hunting large game plays a vital role in the protection of our people, our resources, and the animals themselves. To begin, the killing of large…
The PRNP gene and Variant Creutzfeldt-Jakob disease (vCJD) vCJD is a rare and fatal neurodegenerative disease, first described in 1996 in the United Kingdom (UK) (WHO,2014). It is off a group known as prion diseases which are also known as transmissible spongiform encephalopathies (TSE), effecting both humans and animals. There are three types of prion diseases acquired, genetic and sporadic. Acquired diseases are those such as vCJD and Kuru, these require exposure to external prions to become…
Creutzfeldt-Jakob Disease Creutzfeldt-Jakob Disease is a transmissible, rapidly progressing, neurodegenerative disorder, closely related to “mad cow disease” (Gale, 2013). CJD is can be confused as Alzheimer's, but CJD is more rapidly progressing and ultimately leads to death. It is one of many ‘spongiform encephalopathies’ disease that causes fluid filled spaces in the brain called vacuoles that make the brain have a sponge-like appearance. There is an estimated 250 cases per year in the United…
Additionally there have been strict restrictions placed on imported goods from other countries (especially Western Europe) known to have suffered from infections by prions. “To prevent BSE [bovine spongiform encephalopathy or Mad Cow Disease] from entering the United States, severe restrictions were placed on the importation of live ruminants, such as cattle, sheep, and goats, and certain ruminant products from countries where BSE was known to exist. These restrictions were later extended to…
Viviana Esteves Biology 1A Lab October 19, 2015 Mad Cow BSE Mad Cow disease is otherwise known as bovine spongiform encephalopathy (BSE). Bovine means that the disease affects mainly cows and cattle. Spongiform refers to the spongy look of an infected cows brain, prion causes holes and tissues to fold. Encephalopathy is any form of disease to the brain. BSE is found in more in younger cattle and cows. Other forms of BSE are found in humans, cats (feline spongiform encephalopathy), sheeps…
Mad cow disease is a condition that effects the brain. The medical terminology for it is Bovine Spongiform Encephalopathy. If you break down the name, it tells what the disease is. Bovine is the term for a cow, encephalopathy means a disease in the brain, and spongiform describes the appearance of the brain. The term mad cow disease came from the way the cow acts when it has the disease. It is a progressive neurologic disease, affecting the central nervous system. It also effects the immune…
Mad Cow Disease Bovine spongiform encephalopathy (mad cow disease) not only affects cattle, but also public health and commerce. Mad cow disease is a progressive neurological disorder of cattle that results from an unusual transmissible agent called a prion. The nature of the agent is not well understood but scientists think it is a modified form of a normal protein called a prion protein. This prion is pathogenic and it slowly damages a cow’s central nervous system (Bovine). This disease leads…
nature of neural tissue sometimes caused by the expansion of vacuoles in the neurons of the brain (known as vacuolation). The dead neuron (caused by the prions) alert lysosomes to clear up, however these lysosomes burst and kill other neurons (Cobb, 2009). The harmful Prion proteins gather at the synapses of neurones, stopping them functioning; however the ‘spongey’ changes occur in cisternae of the smooth endoplasmic reticulum, between the axons of neurones, and glial cell processes (Soto,…
identifying what mad cow disease is Mad Cow disease is known as bovine spongiform encephalopathy (BSE) in the scientific community. It is a transmittable, degenerative, slow growing fatal disease, which affects the central nervous system of adult cow, formed when a cow eats the central nervous tissue of another cow. Human can be affected by eating Beef that fed on food contain Central nervous system tissue, like the brain. When a human contracts this disease, it is called variant…
