Genomic insights into the evolutionary origin of Myxozoa within Cnidaria [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance Myxozoans are a diverse group of microscopic parasites that infect invertebrate and vertebrate hosts. The assertion that myxozoans are highly reduced cnidarians is supported by the presence of polar capsules, which resemble cnidarian stinging structures called “nematocysts.” Our study characterizes the genomes and ...

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)

Molecular characterization of two Myxidium species (Cnidaria: Bivalvulida: Myxidiidae) infecting barbs in the Sea of Galilee, Israel [PDF]

Parasitology
Myxozoans are parasitic cnidarians that can cause severe damage to fish, resulting in economic losses to aquaculture and fisheries. In Israel, only a few taxonomic studies have been conducted on Myxozoa infecting freshwater fish and none on barb ...

Comparative Multi-Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment. [PDF]

Mol Ecol Resour
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Proteases as Therapeutic Targets Against the Parasitic Cnidarian Ceratonova shasta: Characterization of Molecules Key to Parasite Virulence In Salmonid Hosts

Frontiers in Cellular and Infection Microbiology, 2022
Proteases and their inhibitors play critical roles in host-parasite interactions and in the outcomes of infections. Ceratonova shasta is a myxozoan pathogen that causes enteronecrosis in economically important salmonids from the Pacific Northwest of ...

The Mitochondrial Genomes of a Myxozoan Genus Kudoa Are Extremely Divergent in Metazoa. [PDF]

PLoS ONE, 2015
The Myxozoa are oligo-cellular parasites with alternate hosts--fish and annelid worms--and some myxozoan species harm farmed fish. The phylum Myxozoa, comprising 2,100 species, was difficult to position in the tree of life, due to its fast evolutionary ...

The myxozoan minicollagen gene repertoire was not simplified by the parasitic lifestyle: computational identification of a novel myxozoan minicollagen gene

BMC Genomics, 2021
Background Lineage-specific gene expansions represent one of the driving forces in the evolutionary dynamics of unique phylum traits. Myxozoa, a cnidarian subphylum of obligate parasites, are evolutionarily altered and highly reduced organisms with a ...

A Chitinase from Aeromonas veronii CD3 with the potential to control myxozoan disease. [PDF]

PLoS ONE, 2011
The class Myxosporea encompasses about 2,400 species, most of which are parasites of fish and cause serious damage in aquaculture. Due to the concerns about food safety issues and limited knowledge of Myxozoa life cycle and fish immune system, no ...

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

J Fish Dis
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 ...

Foodborne Illness Outbreaks in Gyeonggi Province, Korea, Following Seafood Consumption Potentially Caused by between 2015 and 2016 [PDF]

Osong Public Health and Research Perspectives, 2018
Objectives Investigations into foodborne illness, potentially caused by Kudoa septempunctata, has been ongoing in Korea since 2015. However, epidemiological analysis reporting and positive K septempunctata detection in feces in Korea has been limited ...
