Crocodile's blood good for you?

Ehm, if not actually the blood, the crocodile's remarkable ability to fight bacterial infections might be a new source for powerful antibiotics, according to this article:

Perhaps they also should check out the blood to our dear dragon, the Komodo varan.
As I've heard, it isn't particularly assiduous in its use of toothbrush, so rotting pieces of meat filled with bacteria are commonly found wedged in between its teeth (I haven't checked whether this is true myself, though).
This rather bad oral hygiene is perhaps defensible if it has a very strong immune system, although I won't invite them to any parties unless they clean themselves properly.

 

Speaking of the devil..
