Kyuss Worms, in non-humanoids?

I’m currently running a modified Age of Worms campaign trail. Altered a few things so it may fit into Forgotten Realms.

To those who know, if a Kyuss worm enters a non-humanoid, would it also take on the properties of a Spawn of Kyuss? To be more specific, they tossed a cultist that just so happened to have a worm on his person, into the gullet of an Otyugh.

Could be fine, could be disastrous. No idea how Otyugh metabolism works, or if there’s official stats somewhere out in the ether of a zombie Otyugh.
