Molecular confirmation of pearl formation in arctic mussels (Mytilus edulis) caused by Gymnophallus bursicola (Odhner 1900) metacercariae [PDF]

open access: yesParasitology, 2023
In recent field studies, suspected gymnophallid metacercariae were histologically located in the mantle of mussels from the Norwegian Sea. Mussels from the sites in which that infection was detected also presented abnormally high pearl numbers.

Alternative Development Strategies of Clinostomum chabaudi (Digenea) Metacercariae in Frog Hosts (Hyperolius spp.)

open access: yesDiversity, 2021
Clinostomum metacercariae are common endoparasites of fish and frogs. In this study, we examine taxonomic identity and developmental strategy of Clinostomum metacercariae infesting reed frogs Hyperolius kivuensis and H. viridiflavus in Rwanda.

Morphological and molecular assessment of muscle metacercariae infecting tench Tinca tinca from fish farms and wild populations in Germany [PDF]

open access: yesScientific Reports
Fish can be infected with metacercariae (the final larval stage) of different species of potentially zoonotic digenetic trematodes (flukes). The fish-borne zoonotic trematodes thus compromise food safety and present a major threat for human health ...

METACERCARIAL INFECTION IN THE MUSCLES OF TILAPIA NILOTICA AND CLARIAS LAZERA AND THE EFFECT OF SOME PHYSICAL AND CHEMICAL FACTORS ON THE VIABILITY OF ENCYSTED METACERCARIAE [PDF]

open access: yesAssiut Veterinary Medical Journal, 1993
Macroscopic encysted metacercariae in muscles of Clarias lazera were proved to be the larval stage of Cynodip < /em>lostomum azimi, while the microscopic ones obtained from both Clarias lazera and Tilapia nilotica were found to be those of ...

Cockle as Second Intermediate Host of Trematode Parasites: Consequences for Sediment Bioturbation and Nutrient Fluxes across the Benthic Interface

open access: yesJournal of Marine Science and Engineering, 2021
Trematode parasites are distributed worldwide and can severely impact host populations. However, their influence on ecosystem functioning through the alteration of host engineering behaviours remains largely unexplored.

Spatial distribution of skin and muscle metacercariae (Digenea) of roach, Rutilus rutilus, and bleak, Alburnus alburnus (Actinopterygii: Cypriniformes: Cyprinidae), from an estuary lake in central Europe [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2019
Adult stages of digenean flukes are usually well studied, but their larval forms, the metacercariae, do not receive comparable attention of researchers.

COMPARISON BETWEEN TWO METHODS OF METACERCARIAE OF Ascocotyle sp (Trematoda: Digenea) EXTRACTION FROM TISSUES OF Mugil liza Valenciennes, 1836 (Teleostei: Mugilidae)

open access: yesCiência Animal Brasileira, 2014
The demand and consumption of fish and their derivatives has increased considerably in recent years. However, fish are ideal hosts of numerous parasites, highlighting the need to develop new research methodologies for its detection.

The influence of environmental factors on Clinostomum sp. (Digenea) infection in the fish Cichlasoma paranaense (Kullander, 1983) in Central Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2021
This study analyzed the parasitism by Clinostomum sp. metacercariae of the neotropical fish Cichlasoma paranaense (Kullander 1983) and environmental variables’ influence on their host-parasite relationship in Central Brazil.

Molecular and morphological characterisation of flatworm larvae parasitising on fish in Cat Tien National Park, Vietnam

open access: yesNature Conservation Research: Заповедная наука, 2020
Cat Tien National Park in southern Vietnam provides a unique opportunity to study the diversity of parasites associated with animals of the plains of tropical forests and lowland river basins in Southeast Asia.
