Evidence that prions were responsible for mad cow disease?
At one time, cattle were fed the unwanted parts of ground up sheep. Some of those cows became infected with mad cow disease. Mad cow disease spread to humans. Cattle were also fed parts of ground up cow parts, cows eating ground up cattle were infected with that disease. The breakthrough came in New Guinea. There, women and children would eat the brains of dead people. Men would not. Women and children would catch a disease similar to mad cow disease. Men would not. That made it obvious that the disease came from something common to women and children and not to men. Since they behaved the same as nearby groups except for eating the brains of dead people, that had to be the difference. The only difference in the brains of the dead people with mad cow disease and those without mad cow disease was the prions. This was then tested in England where mad cow disease was common. The only difference between cows with mad cow disease and those without mad cow disease were the same prions. The people with mad cow disease had the same prions in their brains.
What are ineffective proteins known as?
They are known as prions and cause many diseases such as Mad Cow Disease and Creutzfelt-Jacob disease.
How do prions get into a cow's brain?
Prions can enter a cow's brain through consumption of contaminated feed or by contact with infected bodily fluids. Once in the brain, prions cause misfolding of normal proteins, leading to the progression of diseases like BSE (mad cow disease).
What is a disease in cattle associated with prions?
One disease of cattle caused by a prion is BSE (Bovine Spongiform Encephalopathy) aka Mad Cow Disease
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 the likely causative microorganism in mad cow disease?
Prions.
Can mad cow disease by identified by a gram stain?
Mad Cow Disease cannot be identified by a gram stain. Mad Cow Disease is caused by prions, incorrectly folded proteins. Gram staining is a way to separate bacteria into two groups - positive and negative - and cannot be used to identify prions, since prions are not bacteria.
What is the causes mad cow disease?
infectious proteins called prions
Can you catch mad cow disease from person to person?
Yes, that is precisely how you contract mad cow.

Can you build up a resistance to mad cow disease?
No. Mad Cow Disease is caused by prions, or misfolded proteins, not bacteria or viruses. Your immune system cannot nor have any means of fighting these prions because they are not recognized by the immune system as a threat.
What are ineffective proteins known as?
They are known as prions and cause many diseases such as Mad Cow Disease and Creutzfelt-Jacob disease.
Do mosquitoes carry mad cow disease?
No, mosquitoes do not carry mad cow disease. Mad cow disease, or Bovine Spongiform Encephalopathy (BSE), is caused by prions that affect cattle and is not transmitted by insects. The disease primarily spreads through the consumption of infected animal products. Mosquitoes are not involved in the transmission of prion diseases like mad cow disease.
Is mad cow disease caused by microbes?
No. They're caused by prions, which are FAR tinier than microbes.

Does the viroid prion virus or the vector cause mad cow disease?
Mad cow disease, also known as bovine spongiform encephalopathy (BSE), is caused by prions. Prions are abnormal proteins that can cause normal proteins in the brain to become misshapen, leading to neurodegeneration. The disease can be spread through contaminated meat consumption.
