Fish Gut Metabarcoding Detects Diets and Parasites Simultaneously

Environmental DNA, Volume 6, Issue 6, November–December 2024.
Understanding dietary habits and trophic niches of species is crucial for the conservation and management of species and ecosystems. We applied a multimarker metabarcoding approach to assess the diet and parasites of commercially exploited beaked redfish (Sebastes mentella).

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

EFSA 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.

Ultrastructure of the extraordinary pedal gland in Asplanchna aff. herricki (Rotifera: Monogononta)

Journal of Morphology, Volume 285, Issue 9, September 2024.
The freshwater rotifer Asplanchna aff. herricki possesses a singular pedal gland that secretes a long mucus thread while swimming. The gland is syncytial, binucleate, and produces large membrane‐bound secretion vesicles that fuse and eventually go through a phase transition to a mesh‐like secretion.

CRISPR‐Cas9‐mediated host signal reduction for 18S metabarcoding of host‐associated eukaryotes

Molecular Ecology Resources, Volume 24, Issue 6, August 2024.
Abstract Metabarcoding‐based methods for identification of host‐associated eukaryotes have the potential to revolutionize parasitology and microbial ecology, yet significant technical challenges remain. In particular, highly abundant host reads can mask the presence of less‐abundant target organisms, especially for sample types rich in host DNA (e.g ...
