Insights into the role of deep-sea squids of the genus Histioteuthis (Histioteuthidae) in the life cycle of ascaridoid parasites in the Central Mediterranean Sea waters

open access: yesScientific Reports, 2021
Ascaridoid nematodes comprise a wide range of heteroxenous parasites infecting top fish predators and marine mammals as definitive hosts, with crustaceans, squids, and fishes acting as intermediate/paratenic hosts.

Various evolutionary avenues of Nematoda to parasitism in Gastropoda

open access: yesSoil Organisms, 2018
The various associations between nematodes and gastropods, which range from random transportation to endophoresis, necromeny, larval parasitism and an entire parasitic or parasitoidic life-style with and without intermediate or paratenic hosts, are ...

To grow or not to grow? Intermediate and paratenic hosts as helminth life cycle strategies [PDF]

open access: yesJournal of Theoretical Biology, 2009
Larval helminths in intermediate hosts often stop growing long before their growth is limited by host resources, and do not grow at all in paratenic hosts. We develop our model [Ball, M.A., Parker, G.A., Chubb, J.C., 2008. The evolution of complex life cycles when parasite mortality is size- or time-dependent. J. Theor. Biol.

Contrasting the population genetic structure of a specialist (Hexaglandula corynosoma: Acanthocephala: Polymorphidae) and a generalist parasite (Southwellina hispida) distributed sympatrically in Mexico

open access: yesParasitology, 2023
Polymorphidae is a monophyletic group of acanthocephalans distributed worldwide. Within this family, Hexaglandula corynosoma is a specialist species that uses a single bird species as a definitive host.

Possible Role of Fish and Frogs as Paratenic Hosts ofDracunculus medinensis, Chad [PDF]

open access: yesEmerging Infectious Diseases, 2016
Copepods infected with Dracunculus medinensis larvae collected from infected dogs in Chad were fed to 2 species of fish and tadpoles. Although they readily ingested copepods, neither species of fish, Nile tilapia (Oreochromis niloticus) nor fathead minnow (Pimephalis promelas), were found to harbor Dracunculus larvae when examined 2-3 weeks later ...

Nematode eel parasite found inside acanthocephalan cysts - a "Trojan horse" strategy?

open access: yesParasites & Vectors, 2014
Background The invasive eel parasite Anguillicoloides crassus (syn. Anguillicola crassus) is considered one of the major causes for the decline of the European eel (Anguilla anguilla) panmictic population. It impairs the swim bladder function and reduces
