We know the same thing we had at ycombas samatra rhino preserve in Indonesia, we all of a sudden were losing some rhinos and come to find that it was a trypanosome infection being spread in the area. And it was being passed from the local domestic cattle, which sort of had their own immunity build up to it, to the neophyte rhinos that didn’t have an immunity to it. So there are a lot of intricate things like this that only scientific studies can find. And you do this by doing the blood work on, not only the animal, having the problem, but on the surrounding animals that might be serving as vectors.
