Acanthocephalan Diseases The phylum Acanthocephala is a relatively small taxon with respect to species number. Arthropods are generally required as intermediate hosts, with adult worms residing in the gut of vertebrates. Characteristic features of the phylum include the state of eutely, a single proboscis that is armed with spines or hooks, and they are generally small and cylindrical. Pathology: Infection of the arthropod intermediate host is passive, occurring when the host ...

Acanthocephala is a phylum of parasitic worms known as acanthocephalans, thornyheaded worms, or spinyheaded worms, characterized by the presence of an evertable proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host. Acanthocephalans have complex life cycles, involving at least two hosts, which may include invertebrates, fishes, amphibians, birds, and mammals. About 1150 species have been described.

Acanthocephala a phylum of elongate, mostly cylindrical organisms with an anterior proboscis covered with many hooks, parasitic in the intestines of most classes of vertebrates. Acanthocephalans are not encountered as commonly as parasitic flatworms (trematodes and tapeworms) or nematodes, but are found in many species of fishes, amphibians, birds, and mammals. The most distinguished morphological characteristic to separate acanthocephalans from other parasitic worms is ...
