I have microbe Mad Cow Disease (I forgot the scientific name already...)
Also known as Bovine Spongiform Encephalopathy http://en.wikipedia.org/wiki/Bovine_spongiform_encephalopathy
And I bet you didn't know that Leptospirosis (Weil's disease) that is mostly carried by rats is also found in cattle as well as many other animals.
The disease is rare in humans who mainly contract it by not cleaning and covering wounds or washing there hands before eating/smoking.
