Runamuk, I know there are a bunch that deny the problem as one caused by domestic sheep. I've looked at the research and the real world examples. There are too many examples of herds doing well, they intermingle, then they all die. Like I said, it's like the topic of evolution. If you choose to turn your head at where the science is pointing, you can do that. I can say the grazing constituents are strong and like to throw a wrench in the spoke. I have read much of what Besser has said and the issue is fairly clear. This issue was being studied 15 years ago, and the consensus then was domestic sheep caused the problems. We are still researching it and can forever. The point is that when you put domestic sheep and bighorns in the same pen, the bighorns die. I can't tell you the exact reason why, but they do. That's all the research I need.
Pasturella is a lovely human bug as well. (to answer your ? Run) immunity is alot easier to stimulate with viruses. Has to do with your memory cells and immunoglobulin levels. It does happen to a certain extent with some bacteria. ..but its sort of like how you never get immune to Strep Throat. You can have it time and time again, whereas most viruses, like Mono, you can have it then immune to that strain for life. They are getting better and better at figuring out the protiens etc, like the pneumovax. Thanks for weighing in Doublelung and ramslam.
