| molecular characterization of five sarcocystis species in red deer ( cervus elaphus), including sarcocystis hjorti n. sp., reveals that these species are not intermediate host specific. | muscle tissue from 37 red deer from norway was examined for sarcocysts. sarcocysts from 2 reindeer were obtained for comparative studies. cysts were excised and morphologically classified by light microscopy, scanning electron microscopy, and dna sequence analysis. five sarcocystis species, sarcocystis hjorti n. sp., sarcocystis hardangeri, sarcocystis ovalis, sarcocystis rangiferi, and sarcocystis tarandi, were found. all 5 species have previously been identified from either reindeer or moose b ... | 2010 | 19961651 |
| Morphological and molecular characterization and phylogenetic placement of Sarcocystis capreolicanis and Sarcocystis silva n. sp. from roe deer (Capreolus capreolus) in Norway. | Sarcocysts were isolated from the muscle tissue of three roe deer from southeastern Norway and examined by light microscopy, scanning electron microscopy and/or sequencing of the small subunit ribosomal RNA (ssu rRNA) gene. By light microscopy, four sarcocyst types were found, including those of Sarcocystis gracilis and Sarcocystis oviformis, which had been characterized previously. The third cyst type had about 10 µm long, flexible, hair-like surface protrusions, consistent with those of Sarcoc ... | 2011 | 21853224 |
| sarcocystis species in red deer revisited: with a re-description of two known species as sarcocystis elongata n. sp. and sarcocystis truncata n. sp. based on mitochondrial cox1 sequences. | in a previous investigation, five sarcocystis species were described from norwegian red deer and believed to be conspecific with species occurring in either reindeer or moose based on sarcocyst morphology and nucleotide sequences of the nuclear ribosomal dna unit. the aim of the present study was to characterize numerous isolates of these sarcocyst types at the mitochondrial cytochrome c oxidase subunit i gene (cox1) in order to corroborate or refute previous species designations of sarcocystis ... | 2014 | 24230915 |
| phylogenetic relationships among sarcocystis species in cervids, cattle and sheep inferred from the mitochondrial cytochrome c oxidase subunit i gene. | coccidian parasites in the genus sarcocystis have a two-host life cycle, and have traditionally been identified on the basis of morphological features of the sarcocyst stage in their intermediate hosts. additional molecular species identification, delimitation and phylogeny of sarcocystis spp. have been based mainly on the nuclear ssrrna gene. this gene is well suited for discrimination between more distant species but less so for closely related species. the objective of this study was therefor ... | 2013 | 23542092 |
| genetic characterisation of six sarcocystis species from reindeer (rangifer tarandus tarandus) in norway based on the small subunit rrna gene. | six sarcocystis species, i.e. sarcocystis grueneri, sarcocystis rangi, sarcocystis tarandivulpes, sarcocystis hardangeri, sarcocystis rangiferi and sarcocystis tarandi have previously been described from reindeer based on sarcocyst morphology. in order to validate and expand the species descriptions, the complete small subunit (ssu) rrna gene was sequenced and used to genetically characterise the six species. the aim was to reveal possible genetic variation in the ssu rrna gene within each sarco ... | 2007 | 17416466 |
