| susceptibility to myxobolus cerebralis among tubifex tubifex populations from ten major drainage basins in colorado where cutthroat trout are endemic. | establishment of myxobolus cerebralis (mc) resulted in declines of wild rainbow trout oncorhynchus mykiss populations in streams across colorado during the 1990s. however, the risk for establishment and spread of this parasite into high-elevation habitats occupied by native cutthroat trout o. clarkii was unknown. beginning in 2003, tubificid worms were collected from all major drainages where cutthroat trout were endemic and were assayed by quantitative pcr to determine the occurrence and distri ... | 2014 | 24689955 |
| comparison of 18s and its-1 rdna sequences of selected geographic isolates of myxobolus cerebralis. | myxobolus cerebralis, the myxosporean parasite-causing salmonid whirling disease, was first reported among rainbow trout (oncorhynchus mykiss) in germany in 1903. the parasite was reported for the first time in north america in 1958 among hatchery-reared trout in the eastern usa, presumably arriving with frozen trout shipments from europe. a comparison of 18s and its-1 ribosomal dna sequences was conducted to identify potential strain differences between selected geographic isolates of this para ... | 1999 | 10404274 |
| myxobolus neurotropus infecting rainbow trout in alaska, a new geographic record. | the alaska department of fish and game fish pathology laboratory received a rainbow trout oncorhynchus mykiss from the alaska peninsula that was suspected of having whirling disease based on the display of aberrant swimming behavior and a deformed spine. we tested for myxobolus cerebralis using standard pepsin-trypsin digest and molecular procedures, which yielded negative results. however, many oval shaped myxospores were observed in brain smears and were confirmed to be those of the morphologi ... | 2012 | 23066815 |
