Les Cestodes Pseudophyllidae dans les écosystèmes aquatiques

Abstract

The Pseudophyllidean cestodes are mainly parasites inhabiting aquatic ecosystems. Their life cycle involves several intermediate hosts, predominantly copepods and fish, before reaching the definitive host, particularly piscivorous animals. Diphyllobothrium latum, parasite responsible for diphyllobothriosis in humans following the ingestion of raw or undercooked fish, Tetragonoporus calyptocephalus, a marine parasite generally found in whales, are among the most notable species. These parasites play a significant role in aquatic ecosystems while also being of interest to medicine and animal health. This work highlights the general characteristics of Pseudophyllidean cestodes, their morphology, life cycle, and medical and veterinary importance. It also emphasizes the methods of diagnosis, treatment, and prevention of these parasitic diseases.
