Susceptibility of two strains of rainbow trout (one with suspected resistance to whirling disease) to Myxobolus cerebralis infection.
The susceptibility of 2 strains of rainbow trout Oncorhynchus mykiss, 1 from North America (TL) and 1 from Germany (GR), to Myxobolus cerebralis (the cause of salmonid whirling disease) was assessed following exposure to the infectious stages (triactinomyxons). Two laboratory experiments were conducted with age-matched rainbow trout of each strain. At the beginning of the study, the 2 trout str...
متن کاملThe effects of Myxobolus cerebralis on the physiological performance of whirling disease resistant and susceptible strains of rainbow trout.
The development of rainbow trout Oncorhynchus mykiss strains that are resistant to whirling disease has shown promise as a management tool for populations in areas where Myxobolus cerebralis is present. However, the physiological effects of the disease on characteristics necessary for fish survival in natural river conditions have not been tested in many of these strains. Five rainbow trout str...
متن کاملPersistent infection of Myxobolus cerebralis, the causative agent of salmonid whirling disease, in Tubifex tubifex.
The objective of this study was to quantify and determine the periodicity in the release of the triactinomyxon (TAM) stage of Myxobolus cerebralis, the causative agent of salmonid whirling disease, by its aquatic oligochaete host Tubifex tubifex. For this, 24 individual T. tubifex (infected as a group at 15 C) were examined daily for the release of M. cerebralis TAMs, and the number of waterbor...
متن کاملA RNAi-based therapeutic proof of concept targets salmonid whirling disease in vivo
Myxobolus cerebralis is a cnidarian-myxozoan parasite that causes salmonid whirling disease. M. cerebralis alternates between two hosts: (1) a vertebrate salmonid and (2) an invertebrate oligochaete, Tubifex tubifex. There is no successful treatment for salmonid whirling disease. MyxSP-1 is a M. cerebralis serine protease implicated in whirling disease pathogenesis. We hypothesized that short-i...
متن کاملHatchery Performance of a Whirling-Disease Resistant Strain of Rainbow Trout
The hatchery and field performance of a whirling disease resistant strain of rainbow trout (Oncorhynchus mykiss) was compared to a traditional Utah strain: Ten Sleep (TS). The resistant strain consisted of progeny from a German strain (GR) x Harrison Lake strain (HA) backcrossed with the German strain, resulting in fish that were 3⁄4 German strain x 1⁄4 Harrison Lake strain. The disease resista...
