In general the smaller the mammal the faster it's metabolic rate (with some exceptions). A faster metabolic rate generates more heat. Flight also requires a lot of effort and the metabolic rate goes quite high while animals are flying. In birds we see a typical core temperature of 102-109F and bats 99-106F.

And since bats are the only mammals that fly it would be a good guess to say they might have the highest body temperature of all mammals.

Just the fact that they are mammals and can cover large distances make them pretty effective diisease vectors, it would seem.
