Integrative taxonomic approach to the cryptic diversity of Diplostomum spp. in lymnaeid snails from Europe with a focus on the ‘Diplostomum mergi’ species complex [PDF]

Parasites and Vectors, 2015
Background Recent molecular studies have discovered substantial unrecognised diversity within the genus Diplostomum in fish populations in Europe and North America including three species complexes.

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response? [PDF]

Journal of Fish Diseases
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

Competent Non-Native Alternative Host Reduces Infection Success in a Generalist Parasite. [PDF]

Ecol Evol
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

Parasitic Infections of Freshwater Fish in Kenya: Prevalence Patterns, Ecological Drivers, and Implications for Aquaculture Sustainability. [PDF]

J Parasitol Res
Fish parasitic infections present a growing threat to freshwater aquaculture in Kenya, affecting fish health, reducing productivity, and limiting the economic potential of small‐scale and commercial farms. This review provides the first consolidated national checklist of freshwater fish parasites in Kenya, synthesizing evidence from lakes, rivers, and ...

Helminth fauna of the black goby Gobius niger L. (Gobiiformes: Gobiidae) from the Finnish Archipelago, Baltic Sea: Molecular and morphological data [PDF]

Current Research in Parasitology and Vector-Borne Diseases
Black gobies (Gobius niger) from the Finnish Archipelago, Baltic Sea, were screened for helminth infections in summer 2020. Helminths were identified morphologically and/or molecularly.

Hybridization and Immunology in Animals: A Review. [PDF]

Ecol Evol
Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathogen dynamics, with important implications for disease ecology and One Health.

Natural occurrence of Diplostomum spp. in farm-raised African catfish ( Clarias gariepinus ) from Oyo state, Nigeria

International Journal of Veterinary Science and Medicine, 2016
Diplostomum species are the parasites responsible for diplostomiasis in fish which may cause blindness, eyefluke, severe ocular disease, opacity of the lens and many other affections. The parasites use many organisms including fish as a host.

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

J Fish Biol
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 ...

The Effects of Hybridization and Parasite Infection on the Survival and Behaviour of Endangered Landlocked Salmon Subject to Predation-Implications for Genetic Rescue. [PDF]

Evol Appl
ABSTRACT A prerequisite of genetic rescue in endangered and genetically depauperate populations is to pre‐evaluate between possible pros and cons of hybridization for the life history and survival of the target population. We hybridized the critically endangered Saimaa landlocked salmon (Salmo salar m.

Another plea for 'best practice' in molecular approaches to trematode systematics: Diplostomum sp. clade Q identified as Diplostomum baeri Dubois, 1937 in Europe. [PDF]

Parasitology, 2022
AbstractDNA sequence data became an integral part of species characterization and identification. Still, specimens associated with a particular DNA sequence must be identified by the use of traditional morphology-based analysis and correct linking of sequence and identification must be ensured.
