Myxobolus cerebralis, the parasite that causes whirling disease, has been a major contributor to the reduction in trout populations in the Intermountain West, U.S.A. Myxobolus cerebralis has a obligate, two host life cycle: trout produce spores that are infective to the tubificid worm host, Tubifex tubifex, and the worm produces spores that are infective to trout. Evidence collected from both field surveys in watersheds in Montana as well as laboratory experiments suggest that the structure of the worm community plays an important role in the prevalence and severity of disease in fish. Tubifex tubifex is comprised of several genetic lineages that often coexist in stream communities. Our field work has shown lineage I and III (TI and TIII) coexist in Montana
