Smit1 and Olena Kudlai1,2,3 1 Water Research Group, Unit for Environmental Sciences and Management, North-West University, Potchefstroom, South Africa; 2 Institute of Ecology, Nature Research Centre, Vilnius, Lithuania; 3 Institute of Parasitology, Biology Centre of the Czech Academy of Sciences, České Budějovice, Czech Republic Abstract: South African clinids are a major component of the temperate intertidal regions that are also known to participate in life cycles and transmission of several groups of parasites. However, the knowledge of trematode diversity of these fishes is incomplete. In this study, two species of Clinus Cuvier, the super klipfish Clinus superciliosus (Linnaeus) and the bluntnose klipfish Clinus cot- toides Valenciennes, were collected from six localities along the South African coast and examined for the presence of trematodes. Metacercariae of Cardiocephaloides Sudarikov, 1959 were found in the eye vitreous humour and brain of C. superciliosus and in the eye vitreous humour of C. cottoides. Detailed analyses integrating morphological and molecular sequence data (28S rDNA, ITS2 rDNA-region, and COI mtDNA) revealed that these belong to two species, Cardiocephaloides physalis (Lutz, 1926) and an unknown species of Cardiocephaloides. This study provides the first report of clinid fishes serving as intermediate hosts for trematodes, reveals that the diversity of Cardiocephaloides in South Africa is higher than previously recorded, and highlights the need for further research to elucidate the life cycles of these trematode species. -

Carla Piazzon, ∗ Oswaldo Palenzuela, Ariadna Sitjà-Bobadilla Fish Pathology Group, Instituto de Acuicultura Torre de la Sal (IATS-CSIC), Castellón, Spain ARTICLE INFO ABSTRACT Keywords: The myxozoan parasite Enteromyxum leei causes chronic enteritis in gilthead sea bream (GSB, Sparus aurata) Acquired immune response leading to intestinal dysfunction. Two trials were performed in which GSB that had survived a previous infection Fish IgM with E. leei (SUR), and naïve GSB (NAI), were exposed to water effluent containing parasite stages. Humoral Sparus aurata factors (total IgM and IgT, specific anti-E. leei IgM, total serum peroxidases), histopathology and gene expression Enteromyxum leei were analysed. Results showed that SUR maintained high levels of specific anti-E. leei IgM (up to 16 months), Parasite resistance expressed high levels of immunoglobulins at the intestinal mucosa, particularly the soluble forms, and were Gene expression resistant to re-infection. Their acquired-type response was complemented by other immune effectors locally and systemically, like cell cytotoxicity (high granzyme A expression), complement activity (high c3 and fucolectin expression), and serum peroxidases. In contrast to NAI, SUR displayed a post-inflammatory phenotype in the intestine and head kidney, characteristic of inflammation resolution (low il1β, high il10 and low hsp90α ex- pression). 1.

History of Myxozoan Character Evolution on the Basis of Rdna and EF-2 Data Ivan Fiala1,2*, Pavla Bartošová1,2
Fiala and Bartošová BMC Evolutionary Biology 2010, 10:228 http://www.biomedcentral.com/1471-2148/10/228 RESEARCH ARTICLE Open Access History of myxozoan character evolution on the basis of rDNA and EF-2 data Ivan Fiala1,2*, Pavla Bartošová1,2 Abstract Background: Phylogenetic relationships among myxosporeans based on ribosomal DNA data disagree with traditional taxonomic classification: a number of myxosporeans with very similar spore morphology are assigned to the same genera even though they are phylogenetically distantly related. The credibility of rDNA as a suitable marker for Myxozoa is uncertain and needs to be proved. Furthermore, we need to know the history of myxospore evolution to understand the great diversity of modern species. Results: Phylogenetic analysis of elongation factor 2 supports the ribosomal DNA-based reconstruction of myxozoan evolution. We propose that SSU rDNA is a reliable marker for inferring myxozoan relationships, even though SSU rDNA analysis markedly disagrees with the current taxonomy. The analyses of character evolution of 15 morphological and 5 bionomical characters show the evolution of individual characters and uncover the main evolutionary changes in the myxosporean spore morphology and bionomy. Most bionomical and several morphological characters were found to be congruent with the phylogeny. The summary of character analyses leads to the simulation of myxozoan ancestral morphotypes and their evolution to the current species. As such, the ancestor of all myxozoans appears to have infected the renal tubules of freshwater fish, was sphaerosporid in shape, and had a spore with polar capsules that discharged slightly sideways. After the separation of Malacosporea, the spore of the common myxosporean ancestor then changed to the typical sphaerosporid morphotype. -

A diversity of myxozoans in filtered water samples and in faeces of piscivores (otters and great cormorants) was detected, demonstrating the suitability of lineage specific amplicons for characterising otherwise difficult to sample parasite communities. The importance of using the approach was highlighted by the lack of myxosporean detection using 30 commonly employed, broadly-targeted eukaryote primers. These results suggest that, despite being frequently present in eDNA samples, myxozoans have been generally overlooked in ‘eukaryote- wide’ surveys. -
Histopathological Changes Caused by Enteromyxum Leei Infection in Farmed Sea Bream Sparus Aurata

Fifteen fish from a non-infected farm were included as a control. Clinical signs appeared only in extensively and severely infected fish. We observed Enteromyxum leei almost exclusively in the intestinal tract, and very rarely in the intrahepatic biliary ducts or gall bladder. We observed heavily infected intestinal villi adjacent to par- asite-free villi. Histological changes indicated a parasite infection gradually extending from villus to villus, originating from an initial limited infected area probably located in the rectum. The parasite forms were exclusively pansporoblasts located along the epithelial basement membrane. Periodic acid-Schiff (PAS)–Alcian blue was the most useful histological stain for identifying the parasite and characterising the degree of intestinal infection. We observed severe enteritis in infected fish, with inflammatory cell infiltration and sclerosis of the lamina propria. -

This myxozoan has low host specificity and is the causative agent of myxozoan emaciation disease, known for heavy mor- talities and significant financial losses within Mediterranean, Red Sea, and Asian aquaculture industries. The disease has rarely been documented within public aquaria and, to our knowledge, has never been confirmed within the USA. This case report describes an outbreak of E. leei in a population of mixed-species east African/Indo-Pacific marine fish undergoing quarantine at a public aquarium within the USA. Four of 16 different species of fish in the population, each of a different taxonomic family, were confirmed infected by the myxozoan through cloacal flush or intestinal wet mount cytology at necropsy. -
