Sculpin fish bdellosis in Lake Baikal is caused by leech ectoparasites, which are identified as belonging to the genus Baicalobdella. In addition to Cottocomephorus grewinkii, eight sculpin hosts for Baicalobdella are newly recorded: Paracottus knerii (Cottocomephorinae), and Abyssocottus korotneffi, Asprocottus platycephalus, Batrachocottus baicalensis, Batrachocottus multiradiatus, Cyphocottus megalops, Limnocottus griseus and Procottus major (Abyssocottinae). These host fishes are mass infected by Baicalobdella leeches (up to 75%) in different sites of Lake Baikal. Comparative morphological analysis of Baicalobdella infecting sculpin fishes vs. Baicalobdella torquata proper revealed nine distinctive features that allow confirming a separate systematic position and revalidating original name Baicalobdella cottidarum Dogiel, 1957.
贝加尔湖杜父鱼蛭病是由水蛭外寄生虫引起的，这些水蛭被鉴定为属于贝加尔湖蛭属。除了格氏杜父鱼外，新记录了8种杜父鱼作为贝加尔湖蛭的宿主：克氏副杜父鱼（杜父鱼亚科），以及科氏深海杜父鱼、扁头深海杜父鱼、贝加尔湖蟾杜父鱼、多辐蟾杜父鱼、大眼凹腹杜父鱼、灰湖杜父鱼和大杜父鱼（深海杜父鱼亚科）。这些宿主鱼类在贝加尔湖的不同区域被贝加尔湖蛭大量感染（感染率高达75%）。对感染杜父鱼的贝加尔湖蛭与贝加尔湖蛭本身进行比较形态学分析，发现了9个独特特征，这些特征有助于确认其独立的系统地位，并重新确认1957年Dogiel提出的原名杜父鱼贝加尔湖蛭。
