Dataset: Prevalence of M. cerebralis infection in T. tubifex
| Project: Relationship of Myxobolus cerebralis Infected Tubifex to Infection Rates and Severity of Whirling Disease in Trout: An Integrated Study of Rock Creek, Montana
| |
| Dataset Abstract: Prevalence of Myxobolus cerebralis infections in Tubifex tubifex was measured by determining which collected worms were actively shedding triactinomyxons (TAMs). A subset of worms that were not shedding TAMs were screened for infection using the PCR diagnostic test, and the prevalence of infection was determined. This data table shows results for total prevalence of infected worms. | |
| Significance of Results: Infected T. tubifex exist in hot spots and very specific locations in the drainage; many locations have worms that are not infected, and many locations do not have T. tubifex at all. Infected hot spots can cause disease in fish downstream. | |
| Relevance to Managers: In conjunction with habitat data, these data could be used to identify hot spots. There are only a limited number of regions where T. tubifex are infected, so there may be ways to manage spread of whirling disease by targeting those regions of the drainage that support populations of infected T. tubifex. | |
| Questions Generated: Examine consequences of remediating hot spots. | |
