“…Based on infestation levels observed, the highest prevalence of T. nodulosus infestation in Teletskoye Lake was found for burbot L. lota (100%) and is in good agreement with data (93.0%) reported in 1954 [8]. L. lota has been reported as a common host for T. nodulosus from a wide range of water bodies: Bothnian Bay, Finland (prevalence ranged from 36 to 92%) [17,18]; Baikal Lake, Russia (prevalence 26.7%) [19]; Tsipo-Tsipikan and Kuanda-Chara lakes, Russia (prevalence ranged from 60 to 100%) [20]; etc. We also found T. nodulosus in intestines of L. lota, but these worms apparently were not able to attach to the intestinal mucosa of L. lota and, consequently, were eliminated from the intestine.…”

In the present study, we estimated the levels of infestation of the main fish species that are hosts for two Triaenophorus species: T. crassus and T. nodulosus. The prevalence of T. crassus and T. nodulosus infestations in the intestine of their definitive host–pike Esox lucius was similar (71.0% and 77.4%, respectively). At the same time, the prevalence of T. crassus infestation in muscle tissue was significantly different between the second intermediate hosts, Coregonus lavaretus pidschian (31.4%) and Cor. l. pravdinellus (91.2%), due to considerable differences in their diets. For T. nodulosus, we found significant variations in the levels of prevalence among the second intermediate hosts—100% for Lota lota, 81.8% for Cottus sibiricus 31.9% for Thymallus arcticus, and 24.5% for Perca fluviatilis—that we also explained using different diets. Moreover, analysis of the symmetry of parasite infestations did not reveal any asymmetry between the number of cysts in the left and right body surfaces of the “planktivorous” form/species of whitefish, whereas in the ‘‘benthivorous”, an asymmetry of parasite infestations was found.
