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.
No, prions are smaller still.
That applies to microorganisms of a wide variety of types: bacteria, viruses, prions, protists, fungi, and perhaps a few more. Note that not all bacteria are harmful to people; the same applies to the other categories.
