| tubifex tubifex from alaska and their susceptibility to myxobolus cerebralis. | although widespread throughout the continental united states, myxobolus cerebralis, the myxozoan parasite that causes whirling disease in salmonids, has not been reported from the state of alaska. as part of a risk assessment for the introduction and establishment of m. cerebralis into alaska, the distribution of the invertebrate host tubifex tubifex was surveyed, and its genetic composition and susceptibility to the parasite were determined. many oligochaetes, but no t. tubifex, were collected ... | 2007 | 18314677 |
| 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 |
| potential for dissemination of the nonnative salmonid parasite myxobolus cerebralis in alaska. | myxobolus cerebralis, the myxozoan parasite responsible for whirling disease in salmonids, was first introduced into the united states in 1958 and has since spread across the country, causing severe declines in wild trout populations in the intermountain western united states. the recent detection of the parasite in alaska is further evidence of the species' capability to invade and colonize new habitat. this study qualitatively assesses the risk of further spread and establishment of m. cerebra ... | 2008 | 18942590 |
| expanded geographical distribution of myxobolus cerebralis: first detections from alaska. | the parasite responsible for salmonid whirling disease, myxobolus cerebralis, was introduced to the usa in 1958. it has since spread across the country causing severe declines in wild trout populations, but has never been documented from alaska. however, while assessing the risk of introduction of m. cerebralis into the state, we detected the parasite using a species-specific polymerase chain reaction (pcr) assay. testing of 180 hatchery rainbow trout, oncorhynchus mykiss (walbaum), by pepsin tr ... | 2007 | 17640251 |
