The life history of Pygidiopsis macrostomum Travassos, 1928 (Digenea: Heterophyidae) [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2009
The life history of the trematode Pygidiopsis macrostomum Travassos, 1928 is described for the first time. Rediae and cercariae were obtained from naturally infected snails Heleobia australis (d´Orbigny), a new first intermediate host. Metacercariae were

Variation in the parasite communities of three co‐occurring herbivorous coral reef fishes

open access: yesJournal of Fish Biology, Volume 102, Issue 4, Page 757-772, April 2023., 2023
Abstract Parasites are important, diverse, and abundant components of natural ecosystems and can influence the behaviour and health of their hosts, inter‐ and intraspecific interactions, and ultimately community structure. Coral reefs are one of the world's most biodiverse ecosystems, yet our understanding of the abundance, diversity, and composition ...

A global review of problematic and pathogenic parasites of farmed tilapia

open access: yesReviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

An Integrated Coproscopic and Molecular Method Provides Insights into the Epidemiology of Zoonotic Intestinal Helminths of Dogs across Cambodia

open access: yesTransboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
Introduction. In Cambodia, a limited number of focal surveys targeting dogs in rural communities have reported intestinal helminths of potential zoonotic risk as highly endemic. In this study, we investigated the prevalence, diversity, distribution, and risk predictors associated with zoonotic intestinal helminths infecting pet, community, and pagoda ...

Stictodora fuscatum (Heterophyidae) metacercariae encysted in gobies, Acanthogobius flavimanus [PDF]

open access: yesThe Korean Journal of Parasitology, 1994
The metacercariae of the genus Stictodora encysted in gobies, Acanthogobius flavimanus, purchased from a local market of Haenam-gun, Chollanam-do, were identified as those of S. fuscatum. A total of 1,437 metacercariae were collected from 30 gobies and some of them were orally fed to cats in order to obtain the adult worms. The metacercariae were 0.194-

Annotated checklist and genetic data for parasitic helminths infecting New Zealand marine invertebrates

open access: yesInvertebrate Biology, Volume 141, Issue 3, September 2022., 2022
Abstract Parasitic helminths with complex life cycles require multiple hosts in a particular order to complete their life cycles. Although almost all helminths infect invertebrates at some point in their life cycle, we know very little about which species of invertebrates harbor parasites compared with what is known for vertebrates. In New Zealand, <1%

Unravelling another mystery: Parasite escape and host‐switching vary spatially in non‐indigenous populations of Japanese mystery snails

open access: yesFreshwater Biology, Volume 67, Issue 8, Page 1316-1332, August 2022., 2022
Abstract Due to anthropogenic mechanisms, global freshwater biodiversity is declining, and non‐indigenous species are consistently cited as a major threat to native ecosystems. In particular, exotic freshwater gastropods and their parasites have invaded ecosystems through deliberate introductions and/or accidental transfer.

Optimization of tools for the detection and identification of Cryptocotyle metacercariae in fish: Digestion method and viability studies

open access: yesJournal of Fish Diseases, Volume 44, Issue 11, Page 1777-1784, November 2021., 2021
Abstract Some trematode metacercariae, including marine digeneans belonging to the genus Cryptocotyle, induce black spots in target tissues due to the attraction of fish host melanophores. To promote precise quantification of infection, the counting of black spots has to be confirmed by reliable quantification of metacercariae after tissue digestion ...
