I wouldnt think that many would survive without water to begin with.

It's a toss up on many. I believe most can't survive without a host longer than a few days. Some like Nematodes can survive up to two weeks without a host.

The animal they live off of is the host, not the water lol.

Most bacteria thou need certain conditions to survive in not just the host. Typical airborne bacteria can live on many surfaces but ones that require hosts that are always submerged I would think would require different conditions than those found in the terestrial environment.
