So, If I have a ratfolk plauge bringer alchemist, and he gets a 4,000 GP iron cobra, and then puts the plauge vial in it, what happens when the snake bites someone. Is it sickened for 1 round/level, or nauseated for 1 hour? The nauseated would be really powerful, but it makes some sense based on the fact that the cobra can be used to "drink" potions.
Edit: just realized it could work with your regular mutagen
