Hematological and histopathological changes in Hoplias malabaricus from the São Francisco River, Brazil caused by larvae of Contracaecum sp. (Nematoda, Anisakidae)

open access: yesHelminthologia, 2015
Until now studies in Brazil of the pathological action of Contracaecum sp. larvae in Hoplias malabaricus have been rare. The aim of the present study was to analyze and describe histopathological changes in the stomach of H.

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

open access: yesEFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Practical PCR tools for the delineation of Contracaecum rudolphii A and Contracaecum rudolphii B (Ascaridoidea: Anisakidae) using genetic markers in nuclear ribosomal DNA

open access: yesMolecular and Cellular Probes, 2007
Using genetic markers defined previously in the internal transcribed spacers (ITS-1 and ITS-2) of nuclear ribosomal DNA (rDNA), PCR-coupled restriction fragment length polymorphism (PCR-RFLP) and specific PCR assays were established for the specific detection of each of two morphologically indistinguishable operational taxonomic units (Contracaecum ...

Mullus barbatus L. and Mullus surmuletus L. from western Mediterranean waters (SE Spain) are infected by Hysterothylacium fabri, but not by zoonotic nematodes. Possible impact on fish hosts#

open access: yesJournal of Fish Diseases, Volume 47, Issue 10, October 2024.
Abstract In order to know whether there is a risk of anisakiasis (or anisakidosis) by consumption of fish of the genus Mullus from the western Mediterranean Sea, which are appreciated for their quality, an epidemiological survey was carried out to evaluate the occurrence of zoonotic or potentially zoonotic nematodes in M. barbatus and M.

Opening a can of worms: Archived canned fish fillets reveal 40 years of change in parasite burden for four Alaskan salmon species

open access: yesEcology and Evolution, Volume 14, Issue 4, April 2024.
Parasitic nematodes of the family Anisakidae (anisakids) can use salmon fishes as intermediate hosts in life cycles that terminate in marine mammal definitive hosts. To assess whether the anisakid burden has changed in salmon over time, we dissected a novel data source: chum, coho, pink, and sockeye salmon that were caught, canned, and thermally ...

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 1: ToRs1–3

open access: yesEFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Surveillance data published since 2010, although limited, showed that there is no evidence of zoonotic parasite infection in market quality Atlantic salmon, marine rainbow trout, gilthead seabream, turbot, meagre, Atlantic halibut, common carp and European catfish.
