Abstract: Macroscopic Sarcocystis cysts were detected in the muscles of 28 Mallards (Anas platyrhynchos), 1 Eurasian Wigeon (Anas penelope), and 1 Common Teal (Anas crecca) hunted in Lithuania and Finland. According to the sequences of the 18S rRNA gene, 28S rRNA gene, and ITS-1 region, the macrocysts examined from all 30 ducks belonged to Sarcocystis rileyi. This parasite was found in the Eurasian Wigeon and the Common Teal for the first time. All S. rileyi isolates examined were identical to… Expand
Sarcocystis rileyi (Apicomplexa) in Anas platyrhynchos in Europe with a potential for spread
Four specimens of mallard shot by local hunters (December 2020 to January 2021 along the eastern coastline of the island of Bornholm in the Baltic Sea) were diagnosed with a heavy load of sarcocysts in the musculature, revealing the causative pathogen to be Sarcocystis rileyi, which was originally described in North America in 1893.

The breast and leg muscles of a common eider from northern Norway contained numerous grossly visible cigar-shaped sarcocysts measuring about 5 × 1 mm, the first genetically verified record of S. rileyi in the common eiders, as well as in any bird species in Norway. Expand
Molecular characterisation of Sarcocystis lutrae n. sp. and Toxoplasma gondii from the musculature of two Eurasian otters (Lutra lutra) in Norway
Sequence comparisons revealed that both otters were infected by the same Sarcocystis sp. Expand
Description of Sarcocystis scandentiborneensis sp. nov. from treeshrews (Tupaia minor, T. tana) in northern Borneo with annotations on the utility of COI and 18S rDNA sequences for species delineation
The presence of the functionally important elements of the COI barcode amino acid sequence of S. scandentiborneensis is confirmed, highlighting that structurally or functionally important aspects of the 18S rRNA and COI could expand their utility for delineation of species. Expand
Serosurvey of Toxoplasma gondii, Sarcocystis sp. and Neospora caninum in geese (Anser sp.) from urban parks and captivity.
The results indicate environmental contamination, particularly for the occurrence of antibodies against T. gondii - a zoonosis that causes toxoplasmosis and is transmitted through oocyte ingestion in geese from urban parks in Curitiba, Brazil. Expand
Sarcocystis rileyi in UK free-living wildfowl (Anatidae): surveillance, histopathology and first molecular characterisation
DNA sequencing of UK isolates confirmed S rileyi in the five dabbling duck host species tested and the associated histopathological myopathy is described highlight an emerging issue to European wildfowl species and provides much opportunity for further research. Expand
Molecular characterisation of three regions of the nuclear ribosomal DNA unit and the mitochondrial cox1 gene of Sarcocystis fusiformis from water buffaloes (Bubalus bubalis) in Egypt
A total of 33 macroscopically visible (3–11 × 1–5 mm) sarcocysts of Sarcocystis fusiformis were excised from the oesophagus of 12 freshly slaughtered water buffalos in Giza, Egypt. Genomic DNA wasExpand
Molecular identification of Sarcocystis rileyi sporocysts in red foxes (Vulpes vulpes) and raccoon dogs (Nyctereutes procyonoides) in Lithuania
Strong evidence is provided showing that the red fox and the raccoon dog can serve as final hosts of S. rileyi in Europe; however, transmission experiments are needed for the ultimate approval. Expand
Sarcocystis rileyi emerging in Hungary: is rice breast disease underreported in the region?
Red foxes (Vulpes vulpes) are ubiquitous in Hungary, and a molecular finding in the faeces of one red fox confirms an already established autochthonous life cycle of S. rileyi in the region. Expand
Caryospora-Like Coccidia Infecting Green Turtles (Chelonia mydas): An Emerging Disease With Evidence of Interoceanic Dissemination
Low genetic variability among the coccidia found in green turtle populations with minimal natural connectivity suggests recent interoceanic dissemination of these parasites, which could pose a risk to sea turtle populations. Expand


Identification of Sarcocystis rileyi from the mallard duck (Anas platyrhynchos) in Europe: cyst morphology and results of DNA analysis
Phylogenetic investigation of macrocysts isolated from naturally infected mallard duck from Lithuania showed S. rileyi to be the most closely related to two unnamed Sarcocystis species from anseriforms and to the S. mucosa. Expand
The mallard duck (Anas platyrhynchos) as intermediate host for Sarcocystis wobeseri sp. nov. from the barnacle goose (Branta leucopsis)
The conclusion is drawn that it is one and the same Sarcocystis species in different intermediate hosts, and ITS-1, 18S rRNA, and 28S r RNA gene sequences showed 100% identity. Expand

Morphologic and Molecular Characterization of the Sarcocysts of Sarcocystis rileyi (Apicomplexa: Sarcocystidae) from the Mallard Duck (Anas platyrhynchos)
Diagnostic ultrastructural features and nucleotide sequences should aid in future studies and communications regarding this parasitic taxon, which lends itself to experimentation because its sarcocysts are macroscopic and easily excised from infected birds. Expand
Phylogeny and sequence variability of the Sarcocystis singaporensis Zaman and Colley, (1975) 1976 ssrDNA
Phylogenetic analysis based on the ssrDNA supports the co-evolution of lsrDNA and sSRDNA in S. singaporensis and suggests the probable existence of at least two divergent paralogous ssrDNAs. Expand
