Whirling disease in brook trout? Not sure but I don't think they are prone to it.

Yeah, that was news to me as well. I thought it only affected west slope trout species (rainbow, cutthroat, golden). The report says that the brook trout tested positive for the presence of the bacteria... perhaps some species can carry it and pass it to on others without suffering from it themselves???
I read that whirling disease was imported from northern Europe (1956). Hatcheries in PA accidentally imported/cultivated/stocked rainbows with the disease and the rest is now history.
There is a strain of rainbows (also from Europe) that are thought to be immune to it. Wyoming and Colorado (maybe others) have experimented with stocking this strain.
