A novel Ceratomyxa species (Myxozoa: Cnidaria) infecting an Amazonian catfish.

Parasitology international, 2022
Parasites are important organisms for the health of ecosystems. While the Amazon Basin is home to a great diversity of ichthyofauna, our knowledge of myxozoan diversity in the biome remains relatively limited.

Ellipsomyxa tucujuensis n. sp. (Myxozoa: Ceratomyxidae), a parasite of Satanoperca jurupari (Osteichthyes: Cichlidae) from the Brazilian Amazon.

Parasitology international, 2021
The present study describes a new coelozoic, eukaryotic microparasite of the genus Ellipsomyxa Køie, 2003 (Ceratomyxidae: Myxozoa) found parasitizing the gallbladder of Satanoperca jurupari Heckel, 1840 collected in the Curiaú River Environmental ...

Recent Advances in Our Knowledge of the Myxozoa

Journal of Eukaryotic Microbiology, 2001
ABSTRACT. In the last few years two factors have helped to significantly advance our understanding of the Myxozoa. First, the phenomenal increase in fin fish aquaculture in the 1990s has lead to the increased importance of these parasites; in turn this has lead to intensified research efforts, which have increased knowledge of the development ...

Novel Amazonian Ceratomyxa species (Cnidaria: Myxozoa) with amoeboid plasmodial motility.

Microbial Pathogenesis
Myxosporeans are a diverse group of cnidarian endoparasites of aquatic animals, with more than 2,600 described species. The genus Ceratomyxa includes some 270 species that are mostly coelozoic and infect the gall bladders of mainly marine fish.

Expanding the geographic distribution of the freshwater parasite Ceratomyxa (Cnidaria: Myxozoa) with vermiform-type plasmodia.

Microbial Pathogenesis, 2021
Although species of the genus Ceratomyxa Thélohan, 1892 mostly parasitize marine fish around the world, a surprising diversity of the genus has recently been reported from Amazonian freshwater fish.

The invertebrate host of salmonid fish parasites Ceratonova shasta and Parvicapsula minibicornis (Cnidaria: Myxozoa), is a novel fabriciid annelid, Manayunkia occidentalis sp. nov. (Sabellida: Fabriciidae).

Zootaxa, 2020
Myxosporea (Cnidaria: Myxozoa) are common fish parasites with complex life cycles that involve annelid hosts. Two economically important salmonid-infecting myxosporeans from rivers of the northwestern United States, Ceratonova shasta (Noble, 1950) and ...

Biodiversity and Evolution of the Myxozoa

2003
Myxozoans (phylum Myxozoa) are metazoan parasites utilizing invertebrate and (mainly) aquatic vertebrate hosts. They have in common with cnidarians the possession of virtually identical, highly complex organelles, namely the polar capsules in myxozoan spores, serving for attachment to new hosts and the nematocysts in surface epithelia of cnidarians ...

Ceratomyxa (Myxozoa: Bivalvulida): Robust taxon or genus of convenience?

International Journal for Parasitology, 2009
The genus Ceratomyxa (Myxozoa: Myxosporea: Bivalvulida) contains parasites that typically infect the gall bladders of marine teleosts. Species of this genus have also been recorded from elasmobranchs, while the best known species (Ceratomyxa shasta) is a systemic pathogen of fresh water salmonid fishes. Here we characterise 10 new species of Ceratomyxa

Infection dynamics of Enteromyxum leei (Myxozoa, Myxosporea) in culture water and its effects on cultured olive flounder, Paralichthys olivaceus (Temminck & Schlegel).

Journal of Fish Diseases, 2021
Enteromyxum leei is a causative agent of enteromyxosis, with a wide range of marine fish hosts. Recently, massive morbidity and mortality were caused by E. leei infection in cultured olive flounders in Korea. To reveal a relationship between E.
