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

Invertebrate 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

Freshwater 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

Journal 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 ...

Stictodora sp. (Trematoda: Heterophyidae) recovered from a man in Korea [PDF]

The Korean Journal of Parasitology, 1988
Two adult specimens of heterophyid fluke, which belong to the genus Stictodora, were collected from the stool of a 24-year old man after chemotherapy. The flukes were morphologically characterized by their small body size (0.90~0.98 mm long and 0.38 mm wide) and peculiar structure of ventrogenital sac with armed gonotyl (with about 12~15 spines) not ...

Proteomic analysis of Ascocotyle longa (Trematoda: Heterophyidae) metacercariae

Molecular and Biochemical Parasitology, 2020
Ascocotyle longa is parasitic trematode with wide distribution throughout America, Europe, Africa, and Middle East. Despite the fact that this fish-borne pathogen has been considered an agent of human heterophyiasis in Brazil, the molecules involved in the host-parasite interaction remain unknown.
