Possible zoonotic implications of the discovery of the advanced third stage larva of Gnathostoma turgidum (Spirurida: Gnathostomatidae) in a Mexican fish species

Helminthologia, 2023
Gnathostomiasis in humans is acquired by consumption of any infected second intermediate host or paratenic host. This includes amphibians, snakes and poultry as well as fish. In this work we report for the first time in Mexico the presence of an AdvL3 of

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Abundance of Procamallanus (Spirocamallanus) inopinatus (Nematoda: Camallanidae) in Characiformes fish and associated factors in Midwest Brazil

Anais da Academia Brasileira de Ciências, 2023
The success of Procamallanus (Spirocamallanus) inopinatus infection in fish involves a complexity of variables. This study aims to evaluate the relationship between abundance of P.

Harmonia axyridis (Coleoptera: Coccinellidae) as a host of the parasitic fungus Hesperomyces virescens (Ascomycota: Laboulbeniales, Laboulbeniaceae): A case report and short review

European Journal of Entomology, 2013
Hesperomyces virescens is an ectoparasite of some Coccinellidae, which until the mid-1990s was relatively rarely only reported from warm regions in various parts of the world. Analysis of the host and distribution data of H.

Armless mitochondrial tRNAs in Enoplea (Nematoda) [PDF]

RNA Biology, 2012
The mitochondrial genome of metazoan animal typically encodes 22 tRNAs. Nematode mt-tRNAs normally lack the T-stem and instead feature a replacement loop. In the class Enoplea, putative mt-tRNAs that are even further reduced have been predicted to lack both the T- and the D-arm. Here we investigate these tRNA candidates in detail.

Environmental Filtering Maintains Macroinvertebrate Diversity in the Upper Jinsha River

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Macroinvertebrate community structure differed significantly among water bodies. Species and functional diversity are higher in tributaries than in mainstems, whereas phylogenetic diversity shows no significant spatial differences. The macroinvertebrate community in the upper Jinsha River are mainly deterministic processes.

Molecular determinants archetypical to the phylum Nematoda [PDF]

BMC Genomics, 2009
AbstractBackgroundNematoda diverged from other animals between 600–1,200 million years ago and has become one of the most diverse animal phyla on earth. Most nematodes are free-living animals, but many are parasites of plants and animals including humans, posing major ecological and economical challenges around the world.ResultsWe investigated phylum ...

A globally influential area‐condition metric is a poor proxy for invertebrate biodiversity

Journal of Applied Ecology, Volume 62, Issue 10, Page 2529-2540, October 2025.
Our results highlight the need to incorporate factors beyond habitat type and condition into site evaluations, and to complement metric use with species‐based surveys. Abstract There is increasing demand for standardised, easy‐to‐use metrics to assess progress towards achieving biodiversity targets and the effectiveness of ecological compensation ...

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Advancing aquatic biodiversity assessments of invertebrates using eDNA metabarcoding: A systematic evaluation of primers for marine and freshwater communities

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2408-2430, October 2025.
Abstract Invertebrate richness and community composition are key indicators of aquatic ecosystem health. Compared with morphotaxonomy‐based survey methods, DNA metabarcoding is a highly efficient and scalable biomonitoring approach that has become increasingly used in invertebrate surveys.
