| sarcocystis in moose (alces alces): molecular identification and phylogeny of six sarcocystis species in moose, and a morphological description of three new species. | muscle tissues from 34 moose from southeastern norway and two moose from canada were examined. sarcocysts were excised and morphologically classified by light microscopy, and some cysts were further examined by scanning electron microscopy or dna amplification and sequencing at the small subunit (ssu) rrna gene. in norwegian moose, three sarcocyst types were recognized, yet five sarcocystis species were found by sequence analysis. new names were proposed for three species which could be characte ... | 2008 | 18369663 |
| sarcocystis in norwegian roe deer (capreolus capreolus): molecular and morphological identification of sarcocystis oviformis n. sp. and sarcocystis gracilis and their phylogenetic relationship with other sarcocystis species. | fresh muscle tissue from six roe deer from southeastern norway was examined for sarcocysts. cysts were excised and morphologically classified by light microscopy, and some cysts were further examined by scanning electron microscopy or dna amplification and sequencing of the small subunit (ssu) rrna gene. two sarcocystis species, sarcocystis gracilis and sarcocystis oviformis n. sp., were found and described by morphological and molecular methods. s. gracilis was found in all animals, whereas s. ... | 2009 | 19050921 |
| 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 characteristics of four sarcocystis spp. in canadian moose (alces alces), including sarcocystis taeniata n. sp. | individual sarcocysts were isolated from fresh or alcohol-fixed muscle samples of two moose from alberta, canada, and examined by light (lm) and scanning electron microscopy (sem) and molecular methods, comprising polymerase chain reaction (pcr) amplification and sequencing of the complete18s rrna gene and the partial cytochrome c oxidase subunit i gene (cox1). by lm, four sarcocyst types were recognized, and the sequencing results showed that each type represented a distinct species, i.e. sarco ... | 2014 | 24535735 |
| 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 |
| corvid birds (corvidae) act as definitive hosts for sarcocystis ovalis in moose (alces alces). | epidemiological data and a unique phylogenetic position had suggested that sarcocystis ovalis in moose and red deer might use a definitive host other than canids, felids, or humans. corvid birds and rats were therefore evaluated as potential definitive hosts for this species in a small pilot study. four laboratory rats were each inoculated with 10 or 25 sarcocysts of s. ovalis isolated from moose, but no sarcocystis oocysts were detected in their intestinal mucosa upon euthanasia 2 to 3 weeks la ... | 2010 | 20697910 |
