ANyone know where I can find a Plague Bearer Template or PrC?

ie a Character/Monster whose very breath can cause nausea and whose touch will cause disease...

 

[BigFreekinGoblinoid]

Cancer Mage from BoVD (pg 52) fits this description pretty well, acting as a host for any disease it encounters, and then special touch attacks ( at 5th level )

Vermin Host from CC2 ( pg 204 ) is a template that can be added to any creature

Pretty much exactly everything you want is right here on the WotC site.
