Fasciolopsis buski (Digenea: Fasciolidae) from China and India may represent distinct taxa based on mitochondrial and nuclear ribosomal DNA sequences

Parasites & Vectors, 2017
BackgroundFasciolopsis buski is a zoonotic intestinal fluke infecting humans and pigs, but it has been seriously neglected. It is yet to know whether there is any genetic diversity among F.

Developmental stages in the Digenea

Parasitology, 1964
The naturally oviposited egg ofDasymetra confertais fully embryonated and it hatches only after it is ingested by the snail host,Physaspp.Hatching appears to be in response to some stimulus supplied by the living snail. The stimulus causes the larva to exercise a characteristic series of body movements and to liberate a granular sustance (hatching ...

UTILIZATION OF EXOGENOUS GLUCOSE BY THE REDIAE OF PARORCHIS ACANTHUS (DIGENEA: PHILOPHTHALMIDAE) AND CRYPTOCOTYLE LINGUA (DIGENEA: HETEROPHYIDAE)

The Biological Bulletin, 1967
1. The rediae of P. acanthus and C. lingua and their gastropod hosts T. lapillus and L. littorea, contained substantial amounts of "free" carbohydrate and polysaccharide. The free fraction consisted of glucose and at least one other sugar probably trehalose.2. Rediae and host heptopancreas tissues absorbed exogenous glucose and incorporated significant

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Ultrastructural and molecular study of the microsporidian Toguebayea baccigeri n. gen., n. sp., a hyperparasite of the digenean trematode Bacciger israelensis (Faustulidae), a parasite of Boops boops (Teleostei, Sparidae)

Parasite, 2022
A new microsporidian Toguebayea baccigeri n. gen., n. sp., hyperparasite of Bacciger israelensis (Digenea, Faustulidae), parasite of Boops boops (Teleostei, Sparidae) is described by means of transmission electron microscopy.

The Opecoelidae sperm model and its contribution to phylogeny: spermatozoon ultrastructural particularities of Allopodocotyle pedicellata (Plagioporinae, Digenea, Platyhelminthes)

, 2017
The ultrastructure of the spermatozoon of Allopodocotyle pedicellata (Digenea, Opecoelidae), an intestinal parasite of the teleost Sparus aurata (gilt-head bream), is described by means of transmission electron microscopy (TEM).

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Syllogistic System for the Propagation of Parasites. The Case of Schistosomatidae (Trematoda: Digenea)

Studies in Logic, Grammar and Rhetoric, 2015
In the paper, a new syllogistic system is built up. This system simulates a massive-parallel behavior in the propagation of collectives of parasites.
