"Leptospirosis has been ruled out yet is pushed by a few who with an agenda. Best thing sports people can do is tell them to shut up or provide relevant information and protocol for investigating. Spraying has also been ruled out as a cause. Does not mean the spraying does not have other affects that may cause problems at the population level."
I don't think "ruled out" is a scientifically correct way to state that. If I remember correctly, they did a small study that had inconclusive results on Leptospirosis, and no studies at all rule out long term exposure effects of spraying herbicides and pesticides in timberlands. Correct me if I'm wrong, and show me the studies.
Google "hoof rot elk" and read more than just the WDFW literature. Call me stupid and a redneck, but I was microbiology major way back when, and I'm not signing off on Treponema as a sole cause of the affliction without further evidence. It goes against my training and nature.
Don't think for a moment that WDFW doesn't have their own political agendas that may be playing into the study of this disease.
