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

J Fish Dis
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.

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.

Ecological, Molecular, Histopathological and Public Health Implications of Zoonotic Metacercariae Clinostomum complanatum (Rudolphi, 1814) in the Endemic Anatolian Fish, Alburnus escherichii. [PDF]

Vet Med Sci
• Clinostomum complanatum metacercariae, which has been reported in 23 fish species worldwide and 12 in Türkiye to date, continues to infect local and endemic fish species and will persist in the future. • Considering that Alburnus escherichii and other fish species in which this parasite has been recorded in Türkiye are used in traditional local ...

Fish morphological and parasitological traits as ecological indicators of habitat quality in a Mediterranean coastal lagoon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1229-1244, November 2023., 2023
Abstract Coastal lagoons are key ‘transitional’ aquatic environments for biodiversity conservation. Ecological indicators are useful tools for the management of water resources in the European Union. Among different biological communities, fish are a very sensitive tool to assess environmental integrity.

Loss of species and genetic diversity during colonization: Insights from acanthocephalan parasites in northern European seals

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023
Acanthocephalan parasite communities in northern European landlocked seal populations are impoverished with respect to both species and intraspecific genetic diversity. Interestingly, the loss of genetic diversity within Corynosoma species seems to have been less drastic than in their seal hosts, possibly due to their large local effective population ...

Unlocking the genome of perch – From genes to ecology and back again

Ecology of Freshwater Fish, Volume 32, Issue 4, Page 677-702, October 2023., 2023
Abstract Eurasian perch Perca fluviatilis has been a popular model species for decades in the fields of aquatic ecology, community dynamics, behaviour, physiology and ecotoxicology. Yet, despite extensive research, the progress of integrating genomic perspective into existing ecological knowledge in perch has been relatively modest.

Multispecies coinfections and presence of antibiotics shape resistance and fitness costs in a pathogenic bacterium

Molecular Ecology, Volume 32, Issue 15, Page 4447-4460, August 2023., 2023
Abstract Increasing antimicrobial resistance (AMR) poses a challenge for treatment of bacterial diseases. In real life, bacterial infections are typically embedded within complex multispecies communities and influenced by the environment, which can shape costs and benefits of AMR.

Diplostomum spathaceum and related species.

Parasitology, 2011
This book chapter describes various aspects of diplostomiasis caused by Diplostomum spathaceum: diagnosis, epidemiology, life cycle, transmission, developmental stages, population dynamics, effects of climate change on parasite distribution, and disease control and prevention.
