tubifex collected at 2 different times directly from the 2 field sites in Colorado were exposed to spores of M. The prevalence of infection following experimental exposures of these T. tubifex not releasing triactinomyxons was assessed by the number of these oligochaetes releasing triactinomyxons 3 mo following experimental exposures to spores of M. cerebralis directly following their collection from the field. In the first study, the prevalence of infection ranged from 0.4 to 1.5%, as determined by counting the number of T. The prevalence of infection and susceptibility of the aquatic oligochaete Tubifex tubifex to Myxobolus cerebralis, was examined in 2 studies on the upper Colorado River, Colorado, USA, where whirling disease occurs in wild trout populations. Prevalence and susceptibility of infection to Myxobolus cerebralis, and genetic differences among populations of Tubifex tubifex.īeauchamp, Katherine A Gay, Melanie Kelley, Garry O El-Matbouli, Mansour Kathman, R Deedee Nehring, R Barry Hedrick, Ronald P
