Hysterothylacium Explained

Hysterothylacium is a genus of parasitic roundworms in the family Raphidascarididae. As of 2020 it consists of over 70 species[1] [2] [3] [4] [5] [6] and is considered one of the largest of the ascaridoid genera parasitising fish.

Ecology

Species in the genus complete their life cycle between predatory teleost fish[7] as their final host and various species of invertebrates and teleost as their intermediate hosts. These parasites are not host specific in the larval stages and infect a broad range of fish species; thus they are widely distributed throughout the aquatic ecosystem and exhibit a global distribution. Hysterothylacium aduncum infection in fish has been associated with mechanical damage to the heart, eye and fish musculature which occurs as a result of parasite larval migration.[8] [9] Catastrophic loss of fish fry due to infection with an unknown species of Hysterothylacium has been reported.[10] Human infection is not common but has been reported in Japan.[11]
