Hi all,

Recently, I have read quite a bit about these very issues, for some research I am working on. Please accept my small contribution to this strand, a partial metanalysis of information available about new theories of proteinaceous based diseases, illnesses or syndromes.

In simple terms, there are many diseases or syndromes such as Crutzfeld-Jakobs Syndrome, Mad Cow disease, etc. that scientists believe are being transmitted by RNA, not DNA. This means that a bit of protein (meat, skin, etc.) can carry the RNA to other living mammals by contact with their protein...eg. a cut.

These bits of RNA, as far as is known today, cannot be killed by normal methods with autoclaving or chemical based treatments.

The main idea here is ... throw any item that may have grabbed even a miniscule amount of skin (cutting, scraping, etc) away...if it is being used in the classroom.

I know this is discouraging, yet it is critical to know that the potential is out there. It is believed that these brain based diseases came to cattle (only in England) and man through the poultry and sheep vectors that were infected with their own species' version of these diseases.

There is a lot more to this story. If you have questions, email me.

Sheryl
