Do we need any more reasons to avoid bats really?

They are mobile germ incubation factories - 25% of mammals on the planet are bats just second after rodents.

And they roam quite incredible distances. Keep in mind that there are 1000+ species of bats and that some of them are huge.

25% by species. Bats only make up 1 billion out of 130 billion mammals, as near as I can tell from a quick Google.

Does that 130 billion include or exclude humans and their livestock?

Yep.
