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

BMC 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,

Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

Journal of Fish Diseases, Volume 49, Issue 6, June 2026.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

Spleen as an Alternative Tissue for Estimating Tetracapsuloides bryosalmonae Load, Prevalence and Its Relationship With Proliferative Kidney Disease in Brown Trout

Journal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Accurate pathogen detection is essential in fish health management and disease prevention. Pathogens often target different host tissues, and monitoring alternative target organs can provide important insights into disease progression. We evaluated the spleen as an alternative to the kidney for estimating the load and prevalence of the ...

Henneguya spp. (Myxozoa, Myxosporea, Myxobolidae) parasitizing fishes from Paraná river, Brazil - DOI: 10.4025/actascibiolsci.v20i0.4467

Acta Scientiarum: Biological Sciences, 2008
O exame das brânquias de 240 espécimes de peixes do rio Paraná, região de Porto Rico, Paraná, Brasil, mostrou que cinco espécies possuíam pequenos cistos, cuja observação revelou constituírem plasmódios de Henneguya spp. (Myxozoa, Myxosporea, Myxobolidae)

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

Reviews 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.

Proteomic Analysis of the Parasitic Cnidarian Ceratonova shasta (Cnidaria: Myxozoa) Reveals Diverse Roles of Actin in Motility and Spore Formation

Frontiers in Marine Science, 2021
Myxozoans are widely distributed aquatic obligate endoparasites that were recently recognized as belonging within the phylum Cnidaria. They have complex life cycles with waterborne transmission stages: resistant, infectious spores that are unique to ...

Dietary Differentiation Between Sympatric Ecotypes of Astatotilapia calliptera From Lake Masoko (Kisiba), Tanzania Revealed by Metabarcoding

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Differentiation between sympatric Astatotilapia calliptera ecotypes using dietary metabarcoding reveal presence of resource partitioning. ABSTRACT Sympatric speciation is defined as the formation of new species in the absence of geographic barriers, but the genomic and life history strategy mechanisms underpinning sympatric speciation are still far ...

Understanding Dynamic Molecular Responses Is Key to Designing Environmental Stress Experiments: A Review of Gene and Protein Expression in Cnidaria Under Stress

Molecular Ecology, Volume 34, Issue 9, May 2025.
ABSTRACT Gene and protein expression analyses are powerful tools to investigate the responses of cnidarians to stress, providing information on both genetic and functional variation and capturing dynamic shifts in organismal physiology. As the use of high throughput sequencing to understand responses of cnidarians to stressors is still relatively new ...

Morphological and molecular characterization of Henneguya cystigena n. sp. (Cnidaria, Myxosporea) parasitizing the alimentary tract of yellowfin seabream, Acanthopagrus latus, in the East China Sea

Parasite
A novel myxosporean species was identified. The species formed spherical to ellipsoidal pseudocysts within the alimentary tract wall of a yellowfin seabream Acanthopagrus latus fished in the East China Sea.

Immunological memory in a teleost fish: common carp IgM+ B cells differentiate into memory and plasma cells

Frontiers in Immunology
From ancient cold-blooded fishes to mammals, all vertebrates are protected by adaptive immunity, and retain immunological memory. Although immunologists can demonstrate these phenomena in all fish, the responding cells remain elusive, without the tools ...
