A total of 190 deepwater sculpins, Myoxocephalus thompsoni, collected in 1995 from Michigan waters of Lake Michigan and Lake Huron was examined for parasites. Five parasite species occurred in sculpins from Lake Michigan with Echinorhynchus salmonis being most common. Six parasite species infected sculpins from Lake Huron, with Haplonema sp. the most common. Haplonema sp. is the only gravid helminth species reported from deepwater sculpins. Pleistophora sp. and Trichodina sp. infected sculpins from Lake Huron and Lake Michigan. Parasite species richness for sculpins at the 3 locations ranged from 5 to 6; mean values ranged from 1.18 to 1.39 for examined fish. The restricted diet of deepwater sculpin, which may be related to the depth of its habitat, appears to determine its helminth fauna. Deepwater sculpin may be an important transport host for E. salmonis, Cyathocephalus truncatus, and Eubothrium salvelini to lake trout and burbot that commonly feed on them.
1995年从密歇根湖和休伦湖的密歇根水域采集了共计190条汤普森氏杜父鱼，对其进行寄生虫检查。在密歇根湖的杜父鱼中发现了5种寄生虫，其中鲑棘头虫最为常见。休伦湖的杜父鱼感染了6种寄生虫，其中单线虫属最为常见。单线虫属是从深水杜父鱼中报告的唯一怀有虫卵的蠕虫物种。Pleistophora属和车轮虫属感染了来自休伦湖和密歇根湖的杜父鱼。这3个地点的杜父鱼的寄生虫物种丰富度在5到6之间；所检查鱼类的平均值在1.18到1.39之间。深水杜父鱼有限的食物来源可能与其栖息地深度有关，这似乎决定了它的蠕虫动物群。深水杜父鱼可能是鲑棘头虫、截头杯首绦虫和红点鲑真叶吸虫传播到通常以它们为食的湖鳟和江鳕的重要中间宿主。
