The “new” Cnidaria incorporating oligocellular myxozoans with multicellular cnidarians flouts Ernst Haeckel’s biogenetic law and challenges contemporary hierarchical preconceptions of evolution, development, and biological structure. Instead of distorting definitions of embryos, tissues, and organs in order to bring once - unicellular eukaryotes under ...

Trematodes of the Great Barrier Reef, Australia: emerging patterns of diversity and richness in coral reef fishes [PDF]
The Great Barrier Reef holds the richest array of marine life found anywhere in Australia, including a diverse and fascinating parasite fauna. Members of one group, the trematodes, occur as sexually mature adult worms in almost all Great Barrier Reef ...

ABSTRACT Species’ with more limited dispersal and consequently less gene flow are more likely to form new spatially segregated species and thus contribute disproportionally to endemic biota and global species richness. Aotearoa New Zealand has exceptional endemicity, with 52% of its 54,000 named species endemic, including 32%, 39% and 68% for ...

Tissue Characteristics and Development in Myxozoa
For most of the time that they have been recognised, myxozoans were viewed to lack any tissue-level of development. However, the discovery of malacosporean stages in freshwater bryozoans revealed recognisable tissues in the form of epithelial sheets and musculature.

Ceratothoa steindachneri (Isopoda: Cymothoidae) and Pentacapsula cutanea (Myxozoa: Pentacapsulidae) parasites infecting the blacktail-comber (Serranus atricauda) were considered suitable as biological tags for stock identification around the islands of ...

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]
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.

Environmental DNA techniques can be applied for the simultaneous detection of multiple aquatic wildlife pathogen species. In this study we conducted an eDNA‐based survey monitoring several pathogens of concern in Switzerland. We identify advantages and limitations of eDNA‐based pathogen monitoring versus more conventional methods.

Modulation of the IgM gene expression and IgM immunoreactive cell distribution by the nutritional background in gilthead sea bream (Sparus aurata) challenged with Enteromyxum leei (Myxozoa) [PDF]
The aim of the present work was to determine if a plant protein-based diet containing vegetable oils (VO) as the major lipid source could alter the distribution of IgM immunoreactive cells (IRCs) and the IgM expression pattern in the intestine and ...

Sparicotylosis has been present in Mediterranean aquaculture of the gilthead seabream for the past 25 years, yet disease management and treatments are not effective. This is further jeopardised by global warming and resistance of Sparicotyle chrysophrii to available anthelminthic compounds.

Fish Immune Responses to Myxozoa
This book provides an up-to-date review of the biology of myxozoans, which represent a divergent clade of endoparasitic cnidarians. Myxozoans are of fundamental interest in understanding how early diverging metazoans have adopted parasitic lifestyles, and are also of considerable economic and ecological concern as endoparasites of fish.
