Schistocephalus solidus is a tapeworm of fish, fish-eating birds and rodents. This hermaphroditic parasite belongs to the Eucestoda subclass, of class Cestoda. This species has been used to demonstrate that cross-fertilization produces a higher infective success rate than self-fertilization .

Schistocephalus solidus is isolated in areas of western and eastern North America, including Alaska and provinces of Canada, Europe, and Eurasia. These areas are the ranges of its second intermediate host, Gasterosteus aculeatus (Poulin et al. 2011).

General: Schistocephalus solidus Müller, 1766 is a common, widely distributed fish cestode. The combination of the worm and the three-spined stickleback, Gasterosteus aculeatus (L.), as host is considered a well-studied model organism duo, which is investigated in nature and laboratory experiments all over the world.

Schistocephalus solidus is a tapeworm that requires three hosts in its life cycle: fish, birds and copepods. Sticklebacks become infected after eating an infected copepod.

2021年8月28日 · We studied Schistocephalus solidus during the life stage in which behavioural changes take place in its obligatory intermediate fish host, the threespine stickleback (Gasterosteus aculeatus). We produced a novel genome sequence and assembly of S. solidus to improve protein coding gene prediction and annotation for this parasite.

2018年7月10日 · The tapeworm Schistocephalus solidus develops into a fertile parasite exclusively in the three-spined stickleback. The parasites are best adapted to the fish from their own region of origin.

Schistocephalus solidus is a well-established model organism for studying the complex life cycle of cestodes and the mechanisms underlying host-parasite interactions. However, very few large-scale genetic resources for this species are available.

Our findings point to the presence of a distinct lineage of cryptic Schistocephalus in sculpins from Aleknagik and Iliamna lakes that warrants further investigation to determine appropriate evolutionary and taxonomic recognition.
