Bovine spongiform encephalopathy (BSE, mad cow disease), kuru (a neurologic prion found in one tribe of humans that has since been eliminated after ritual cannibalism of deceased tribe members was discontinued), scrapie (a long-standing problem in sheep) and chronic wasting disease (a relatively new disease identified in deer, elk, moose and other cervids in North America).
What else can I help you with?
All the following diseases are caused by prions except?
Cholera. Prions are known to cause diseases like Creutzfeldt-Jakob disease, mad cow disease, and kuru, but not cholera, which is caused by a bacterial infection.
What Spongiform encephalopathies are thought to be caused by?
Spongiform encephalopathies are thought to be caused by abnormal prion proteins that trigger a cascade of events leading to neuronal death, resulting in sponge-like holes in the brain tissue. These diseases include Creutzfeldt-Jakob disease, variant Creutzfeldt-Jakob disease, and bovine spongiform encephalopathy (mad cow disease).
Can you give me all the information known about Prions?
Prions • Proteinaceous infectious agents (PrP) • Prions are misfolded proteins Diseases caused by prions: • spongiform encephalopothies • BSE (Bovine Spongiform Encephalopathy, aka Mad Cow Disease) • CJD (Creutzfeldt-Jakob disease) • kuru • scrapie in sheep Prions are only destroyed by: • incineration • autoclaving in 1N NaOH
What is the pathogen composed only of protein?
The pathogen composed only of protein is known as a prion. Prions are infectious agents that cause neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, particularly in the brain. Unlike viruses and bacteria, prions do not contain nucleic acids (DNA or RNA) and are resistant to conventional methods of sterilization. Examples of diseases caused by prions include Creutzfeldt-Jakob disease and mad cow disease (BSE).
What are potential dangers of a prion?
Prions are proteins that can cause misfolding of other proteins in the brain, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease in humans. Due to their ability to self-propagate and resist normal sterilization techniques, prions pose a significant risk of spreading through contaminated tissues or medical instruments. Transmissible spongiform encephalopathies caused by prions are currently incurable and fatal.
All the following diseases are caused by prions except?
Cholera. Prions are known to cause diseases like Creutzfeldt-Jakob disease, mad cow disease, and kuru, but not cholera, which is caused by a bacterial infection.
What is infectious diseases caused by?
"germs" -- bacteria, viruses, parasites, fungi, and possibly prions

What diseases are thought to be caused by point mutation?
Sickle cell anemia.
What is the pathogen composed only of protein?
The pathogen composed only of protein is known as a prion. Prions are infectious agents that cause neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, particularly in the brain. Unlike viruses and bacteria, prions do not contain nucleic acids (DNA or RNA) and are resistant to conventional methods of sterilization. Examples of diseases caused by prions include Creutzfeldt-Jakob disease and mad cow disease (BSE).
What is a disease that has a second letter O?
Gonorrhea is one, Bovine Spongiform Encephalopathy is another. Gonorrhea is a sexually transmitted disease caused by a bacteria, whilst BSE is a neurological diseased, thought to be caused by Prions.
What type of diseases can you have if you have a defect in your proteins?
All genetic diseases causes malformation of proteins, as genes are the code for the proteins within us. Also, diseases like mad cow are caused by a misshapen proteins called prions, but one must come in contact with a cow's brain to contract this.
What incomplete viruses have been linked to diseases like scrapie and mad cow?
Prions.
What are potential dangers of a prion?
Prions are proteins that can cause misfolding of other proteins in the brain, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease in humans. Due to their ability to self-propagate and resist normal sterilization techniques, prions pose a significant risk of spreading through contaminated tissues or medical instruments. Transmissible spongiform encephalopathies caused by prions are currently incurable and fatal.
What is the germ theory of disease?
the theory that all contagious diseases are caused by microorganisms...
Does prions cause Alzheimers?
No, prions do not cause Alzheimer's disease. Alzheimer's is characterized by the accumulation of beta-amyloid plaques and tau protein tangles in the brain, while prion diseases, such as Creutzfeldt-Jakob disease, are caused by misfolded prion proteins that lead to brain damage and cell death through a different mechanism.
