Long-term epidemiological survey of Kudoa thyrsites (Myxozoa) in Atlantic salmon (Salmo salar L.) from commercial aquaculture farms [PDF]

open access: yes, 2017
Kudoa thyrsites (Myxozoa) encysts within myocytes of a variety of fishes. While infected fish appear unharmed, parasite-derived enzymes degrade the flesh post-mortem.

A New Species of Myxobolus (Cnidaria: Myxosporea: Myxobolidae) from the Mesenteries of Blackspotted Topminnow, Fundulus olivaceus (Cyprinodontiformes: Fundulidae), from the Upper Ouachita River Drainage, Arkansas, USA

open access: yesDiversity
Between March and August 2024, three species of Fundulus topminnows, including two northern studfish, Fundulus catenatus, six blackspotted topminnows, Fundulus olivaceus, and eleven blackstriped topminnows, Fundulus notatus, were collected from various ...

Serine protease inhibitors of the whirling disease parasite Myxobolus cerebralis (Cnidaria, Myxozoa): Expression profiling and functional predictions

open access: yesPLoS ONE, 2021
Here, we studied the expression pattern and putative function of four, previously identified serine protease inhibitors (serpins) of Myxobolus cerebralis, a pathogenic myxozoan species (Cnidaria: Myxozoa) causing whirling disease of salmonid fishes.

How to build single‐celled cnidarians with worm‐like motility: Lessons from Myxozoa

open access: yesJournal of Anatomy, 2021
Metazoans with worm‐like morphologies across diverse and disparate groups typically demonstrate motility generated by hydrostatic skeletons involving tissue layers (muscles and epithelia).

Description of Myxobolus balatonicus n. sp. (Myxozoa: Myxobolidae) from the common carp Cyprinus carpio L. in Lake Balaton [PDF]

open access: yes, 2015
Myxobolus balatonicus n. sp. was detected in the gill filaments of the common carp Cyprinus carpio L. collected in Lake Balaton, Hungary. Its oval plasmodia measuring 600–800 × 300–400 µm were located intravasally in the filamental arteries.

A genome wide survey reveals multiple nematocyst-specific genes in Myxozoa

open access: yesBMC Evolutionary Biology, 2018
Background Myxozoa represents a diverse group of microscopic endoparasites whose life cycle involves two hosts: a vertebrate (usually a fish) and an invertebrate (usually an annelid worm). Despite lacking nearly all distinguishing animal characteristics,

Tetracapsuloides bryosalmonae infection affects the expression of genes involved in cellular signal transduction and iron metabolism in the kidney of the brown trout Salmo trutta [PDF]

open access: yes, 2015
Tetracapsuloides bryosalmonae is an enigmatic endoparasite which causes proliferative kidney disease in various species of salmonids in Europe and North America. The life cycle of the European strain of T.

Host sexual dimorphism and parasite adaptation [PDF]

open access: yes, 2012
In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response.

An evolutionary genomics view on neuropeptide genes in Hydrozoa and Endocnidozoa (Myxozoa)

open access: yesBMC Genomics, 2021
Background The animal phylum Cnidaria consists of six classes or subphyla: Hydrozoa, Scyphozoa, Cubozoa, Staurozoa, Anthozoa, and Endocnidozoa. Cnidarians have an early evolutionary origin, diverging before the emergence of the Bilateria.

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.
