Project: Characterization of the Response of Genetically Distinct Tubifex tubifex Populations to M. cerebralis Infection in Laboratory and Natural Systems

Primary Investigator: Charlotte Rasmussen
Project Summary: This project entailed a series of experiments to test previous information indicating that genetic differences among T. tubifex contribute to the differences in distribution and severity of whirling disease seen among wild fish populations. The results suggest there are four genetically-distinct clades. The two groups of worms showing high and moderate TAM production may comprise one large related groups, while the remaining two distinct clades consist of low producers and non-producers. Field studies to determine the genetic composition of naturally-occurring T. tubifex populations in order to compare the genetic and biological results obtained from the laboratory experiments were expanded. Preliminary genetic analysis from several streams in Montana indicates that these populations consist of individuals with moderate to high TAM production, which is consistent with the disease epidemiology seen on these river systems.
