| review of myxosporea of importance in salmonid fisheries and aquaculture in british columbia. | several myxosporean parasites are of importance in fisheries and aquaculture in british columbia. the pkx organism and ceratomyxa shasta noble, 1950 cause disease and mortality, kudoa thyrsites (gilchrist, 1924) and henneguya salminicola ward, 1919 are of importance because they infect somatic muscle, cause unsightly cysts and soft flesh, and thus reduce the market value of the fish. myxobolus arcticus pugachev et khokhlov, 1979, an apparently non-pathogenic species, along with h. salminicola, i ... | 1994 | 8050752 |
| the phylogeny of marine and freshwater species of the genus chloromyxum mingazzini, 1890 (myxosporea: bivalvulida) based on small subunit ribosomal rna gene sequences. | the small subunit ribosomal rna gene (ssu rdna) of two freshwater and one marine species of the genus chloromyxum mingazzini, 1890 were sequenced. the ssu rdna trees obtained show the phylogenetic position of the marine species chloromyxum leydigi mingazzini, 1890 to be at the base of the freshwater clade, being well supported by a high bootstrap value. chloromyxum cyprini fujita, 1927 is closely related to chloromyxum truttae léger, 1906 and they represent a sister branch to raabeia sp., myxidi ... | 2004 | 15357399 |
| molecular relationships and phylogeny in a community of myxosporeans and actinosporeans based on their 18s rdna sequences. | the community of myxosporeans and actinosporeans inhabiting a typical scottish highland stream and the outflow area of an adjacent salmon hatchery was analysed on the basis of their 18s rdna sequences. nine myxosporeans belonging to the genera sphaerospora, chloromyxum, zschokkella, myxidium, hoferellus and myxobilatus were identified from mature spores in different organs of the fish species present. twelve actinosporean types belonging to the collective groups of neoactinomyxum, aurantiactinom ... | 2004 | 15380681 |
| molecular phylogeny of the kidney-parasitic sphaerospora renicola from common carp (cyprinus carpio) and sphaerospora sp. from goldfish (carassius auratus auratus). | the genetic relatedness of two kidney-parasitic sphaerospora species was studied. although s. renicola, the causative agent of swimbladder inflammation of common carp fingerlings (cyprinus carpio), and sphaerospora sp. originating from goldfish (carassius auratus auratus) were indistinguishable on the basis of spore morphology, they were found to be genetically different as their 18s rdna sequences shared only 71.9% identical nucleotides. in the phylogenetic trees, sphaerospora sp. from goldfish ... | 2004 | 15595280 |
| renal myxozoanosis in crowned river turtles hardella thurjii: description of the putative agent myxidium hardella n. sp. by histopathology, electron microscopy, and dna sequencing. | chelonian myxozoanosis is rarely reported and has previously not been documented to cause disease. this report describes myxozoanosis associated with significant renal disease in two crowned river turtles (hardella thurjii). one turtle presented with emaciation and died. the cage mate presented with emaciation and was euthanized. histologically, renal intratubular myxozoan spores were associated with renal tubular necrosis, tubular mineralization, and chronic interstitial nephritis, with membran ... | 2005 | 16145205 |
