Ichthyophthirius multifiliis as a potential vector of Edwardsiella ictaluri in channel catfish [PDF]

FEMS Microbiology Letters, 2012
There is limited information on whether parasites act as vectors to transmit bacteria in fish. In this trial, we used Ichthyophthirius multifiliis and fluorescent Edwardsiella ictaluri as a model to study the interaction between parasite, bacterium, and fish. The percentage (23-39%) of theronts fluorescing after exposure to E.

Application of Conservation Genomics to Investigate the Role of Pathogens on the Migration of Sea‐Run Brown Trout (Salmo trutta)

Journal of Fish Diseases, Volume 48, Issue 5, May 2025.
ABSTRACT Pathogens play a key role in individual function and the dynamics of wild populations, but the link between pathogens and individual performance has rarely been investigated in the wild. Migrating salmonids offer an ideal study system to investigate how infection with pathogens affects performance given that climate change and fish farming ...

Parasites of two coexisting invasive sailfin catfishes (Siluriformes: Loricariidae) in a tropical region of Mexico

Neotropical Ichthyology
Currently many species of Amazon sailfin catfishes (Loricariidae) have been introduced to wild environments outside their native range. There is, however, little knowledge about their role as vectors of parasites that can infect native fish or even ...

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom considered and may confound and influence the study species in situ.

The Pathobiome of Salmo trutta From the North Sea to the Barents Sea

Journal of Biogeography, Volume 52, Issue 3, Page 558-570, March 2025.
ABSTRACT Aim Salmonids are some of the best studied species with respect to their pathobiome, and at the northern range limit, there is potential for pathogens to expand with both climate change and increased fish farming in the north. Location We sampled sea‐run brown trout from throughout Norway for gill tissue and conducted both pooled and ...

A Reassessment of Phylogenetic Relationships in Class Oligohymenophorea (Protista, Ciliophora) Based on Updated Multigene Data

Ecology and Evolution, Volume 15, Issue 2, February 2025.
We report 97 new sequences, including SSU‐rRNA, ITS1‐5.8S‐ITS2 rRNA, LSU‐rRNA, mitochondrial cytochrome oxidase c subunit I, and mitochondrial small subunit ribosomal RNA genes of 30 oligohymenophorean populations. A comprehensive analysis of class Oligohymenophorea is conducted, encompassing 250 populations.

Effects of immunosuppression on protection of fry from Ichthyophthirius multifiliis Fouquet 1876 during mouthbrooding of Oreochromis mossambicus (Peters) [PDF]

, 1993
Members of the family Cichlidae belonging to the genus Oreochromis are maternal mouthbrooders. They protect their eggs and early fry from environmental hazards by keeping fry in their buccal cavities, a confined environment. It has been shown that female

eDNA Sampling Systems for Salmon Ecosystem Monitoring

Environmental DNA, Volume 7, Issue 1, January–February 2025.
The lack of simple sampling systems enabling high filtration volumes and rapid sample collection have thus far hindered broad scale eDNA adoption. To overcome these challenges, several modular water sampling systems that utilize hollow‐membrane filtration cartridges were developed that allowed for increased filtration volume and speed from diverse ...
