چکیده
A myxosporean species found to develop in the liver of 10 out of 24 common shrews, Sorex araneus L., caught in South Bohemia, Czech Republic, was identified as Soricimyxum fegati Prunescu, Prunescu, Pucek et Lom, 2007, the unique representative of the genus and the first myxosporean species known to develop from plasmodia to spores in a terrestrial mammal. The original description of this species, based on fixed material, is supplemented with new data based on fresh material and with partial sequence of SSU rDNA (GenBank Acc. No. EU232760). Phylogenetic analysis of SSU rDNA revealed that S. fegati is closely related to myxosporeans infecting gall bladders of freshwater fish.

The phylogenetic position of Myxobolus carnaticus (Myxozoa, Myxosporea, Bivalvulida) infecting gill lamellae of Cirrhinus mrigala (Hamilton, 1822) based on 18S rRNA sequence analysis
Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...

As part of a biodiversity study in northwestern Hungary, we conducted a parasitological survey of small mammals. In both common shrews (Sorex araneus Linnaeus) and pygmy shrews (Sorex minutus Linnaeus), we found myxospores of a species of Soricimyxum Prunescu, Prunescu, Pucek et Lom, 2007 (Myxosporea) and plasmodia in the bile ducts within the liver. Spores from both species of shrewswere morph...
متن کاملMolecular and phylogenetic characterization of Thelohanellus qadrii (Myxozoa, Myxosporea, Bivalvulida) infecting the secondary gill epithelium of Indian major carp, Catla catla (Hamilton, 1822)
Myxosporean taxonomy which is traditionally based on the morphology of the myxospore stage, is in a state of flux given new insights provided by the expanding dataset of DNA sequences. To date, more than 40 species of Thelohanellus from India have been described according to morphometric characteristics. Nevertheless, molecular data on these histozoic myxosporean parasites of freshwater fish ar...

As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare. In this report, the 18S rRNA gene sequence of Myxobolus cuttacki infecting gill lamellae of minor carp Labeo bata (Ham...
متن کاملA comparative phylogenetic analysis of Theileria spp. by using two two "18S ribosomal RNA" and "Theileria annulata merozoite surface antigen" gene sequences
More than 185 species, strains and unclassified Theileria parasites are categorized in the Entrez Taxonomy. The accurate diagnosis and proper identification of the causative agents are important for understanding the epidemiology, prevention and appropriate treatment. This study aims to discuss the importance of two genes of Theileria annulata 18S ribosomal RNA (18S rRNA) and Theileria annulata...
