immunohistochemical reactivity of polyclonal antibodies against sphaerospora testicularis and ceratomyxa labracis (myxosporea: bivalvulida), with other myxosporean parasites.immunological staining with rabbit antibodies raised against sphaerospora testicularis and ceratomyxa labracis was used to characterise their specificity and their reactivity towards other fish parasites. polar capsules and valves of s. testicularis and c. labracis were labelled with their homologous antibody and cross reaction was observed with all the myxosporean parasites assayed from marine and freshwater fish hosts. all polar capsules were stained with both antibodies, except those of zscho ...199910333336
comparative studies on carbohydrates of several myxosporean parasites of fish using lectin histochemical methods.a histochemical study using lectin methods was performed on myxosporean parasites from vastly different fish hosts from marine and fresh waters. six biotinylated lectins were used (wga, sba, bs-i, con-a, uea-i and sna). the binding pattern of con-a and wga revealed the presence of mannose and/or glucose, and n-acetyl-d-glucosamine respectively, in polar capsules and valves of most of the myxosporea assayed. thus, chitin may be present in polar capsules and/or valves of myxosporean spores. the bs ...199910730197
ultrastructural localisation of carbohydrates in four myxosporean parasites.the existence and localisation of carbohydrates in four myxosporean parasites was investigated at transmission electron microscope, using lectin histochemistry techniques. the myxosporea studied showed different lectin binding patterns. n-acetyl-glucosamine or its polymers were predominant in the valves of leptotheca sp. and were also present in sphaerospora dicentrarchi and polysporoplasma sparis ones. mannose and/or glucose terminals were mainly detected in s. dicentrarchi and p. sparis valves ...200011031754
bivalvulidan (myxozoa: myxosporea) parasites of damselfishes with description of twelve novel species from australia's great barrier reef.bivalvulidan parasites from the gall bladder of 31 species of damselfishes (family pomacentridae) were examined for their taxonomic identity and their relatedness to other species of myxozoans. this paper describes 11 novel ceratomyxid species and a novel myxidium sp. each species is characterized morphologically and small subunit (ssu) rdna sequences were used in molecular phylogenetic analyses. five pomacentrid species were found to harbour multiple infections of bivalvulidan species. one spec ...200818771608
morphology, molecular data, and development of zschokkella mugilis (myxosporea, bivalvulida) in a polychaete alternate host, nereis diversicolor.the morphology of zschokkella mugilis sitjà-bobadilla and alvarez-pellitero, 1993 (myxosporea, bivalvulida) in nereis diversicolor o. f. müller, 1776 is described for the first time. the molecular data show that the actinospore has 100% similarity to the myxospore of z. mugilis. fully mature actinospores are tri-radiate, the spore body has a small process, and the sporoplasm has 2 inner daughter cells. in the polychaete, the spores of the parasite develop in groups of 8 inside pansporocysts. the ...200918939897
ellipsomyxa syngnathi sp. n. (myxozoa, myxosporea) in the pipefish syngnathus typhle and s. rostellatus (teleostei, syngnathidae) from denmark.a new species ellipsomyxa syngnathi sp. n. (myxozoa) is described from syngnathus typhle l. and syngnathus rostellatus nilsson, 1855 (syngnathidae), using spore morphology and ssu rdna sequence data. monosporic plasmodia develop in the internal gallbladder wall. the ellipsoid myxospore has two pyriform polar capsules which discharge at opposite sides some distance from both sutural line and spore ends. the myxospore mainly differs from that of ellipsomyxa gobii køie (folia parasitol 50:269-271, ...200919727823
ultrastructural aspects of ellipsomyxa mugilis (myxozoa: ceratomyxidae) spores and developmental stages in nereis diversicolor (polychaeta: nereidae).abstract the ultrastructure of ellipsomyxa mugilis' spores and developmental stages in nereis diversicolor were studied by transmission electron microscopy. the ultrastructure features and the developmental stages show many similarities with the general pattern described for other actinospores. however, several new features are definitely worth notice. for example, tetranucleated cells precedes the formation of the initial pansporocyst, which preserves the 2 original enveloping cells until the ...201222263603
