| myxobolus cerebralis in tubifex tubifex from a whirling disease epizootic in montana. | aquatic oligochaetes from a whirling disease enzootic area in southwest montana were examined for infection with myxobolus cerebralis. anterior portions of oligochaetes were preserved for specific identification, whereas dna was purified from posterior portions. the purified dna was used in a nested polymerase chain reaction (pcr) assay specific for m. cerebralis small-subunit ribosomal dna. naturally infected oligochaetes were identified by a resulting 415-bp fragment of amplified parasite dna. ... | 1998 | 9714199 |
| risk of myxobolus cerebralis infection to rainbow trout in the madison river, montana, usa. | myxobolus cerebralis, the parasite that causes salmonid whirling disease, has had detrimental effects on several salmonid populations in the intermountain west, including the rainbow trout in the madison river, montana, usa. the goal of this study was to examine relationships among characteristics of the environment, tubifex tubifex (the alternate host) populations, and rainbow trout whirling disease risk in the madison river. environmental characteristics were measured in side channels of the m ... | 2006 | 16711061 |
| epizootiology of myxobolus cerebralis, the causative agent of salmonid whirling disease in the rock creek drainage of west-central montana. | whirling disease, caused by the myxozoan parasite myxobolus cerebralis, remains a health threat to salmonid fish in the western united states. although various aspects of this host-parasite system have been studied, investigations examining the overall epizootiology of whirling disease in an ecosystem are lacking. therefore, in june 1998, studies were initiated in the rock creek watershed of west-central montana and continued through 2003 to assess the intensity of infection in trout using senti ... | 2007 | 17436949 |
| epizootiology of myxobolus cerebralis, the causative agent of salmonid whirling disease in the rock creek drainage of west-central montana: 2004-2008. | whirling disease, caused by the myxozoan parasite myxobolus cerebralis , remains a serious health threat to salmonid fish in the western united states. a previously published study on the epizootiology of whirling disease in the rock creek watershed of west-central montana, conducted from 1998 to 2003, showed that the intensity of m. cerebralis infections in sentinel trout increased significantly throughout the drainage and that the range of m. cerebralis had expanded considerably. in addition, ... | 2010 | 19891515 |
