| parasites of waterfowl, from southwest texas: iii. the green-winged teal, anas crecca. | seventy of 72 green-winged teal, anas crecca, from southwest texas were infected with parasites. seventeen species of endoparasites were recorded: notocotylus attenuatus, zygocotyle lunata, typhlocoelum sisowi, echinostoma revolutum, hypoderaeum conoideum, dendritobilharzia pulverulenta, cloacotaenia megalops, sobolevicanthus gracilis, sobolevicanthus krabbeella, gastrotaenia cygni, amidostomum acutum, amidostomum anseris, tetrameres crami, echinuria uncinata, corynosoma constrictum, polymorphus ... | 1981 | 6788963 |

| redescription of the sarcocysts of sarcocystis rileyi (apicomplexa: sarcocystidae). | the intermediate hosts for sarcocystis rileyi (stiles 1893) minchin 1913 are ducks (anas spp.), and the striped skunk (mephitis mephitis) is its definitive host. the structure of sarcocysts from an experimentally infected shoveler duck (anas cylpeata) fed sporocysts from an experimentally-infected m. mephitis was studied and compared with type specimens from a naturally infected duck. the experimentally infected duck was killed 154 d after feeding sporocysts. by light microscopy the sarcocyst wa ... | 2003 | 14733440 |
| morphologic and molecular characterization of the sarcocysts of sarcocystis rileyi (apicomplexa: sarcocystidae) from the mallard duck ( anas platyrhynchos ). | macroscopic sarcocysts are often observed in ducks, but at present their taxonomic status remains uncertain because ducks serve as intermediate hosts for several such parasites in the genus sarcocystis . one such species, sarcocystis rileyi , was long ago established to involve the northern shoveler duck ( anas clypeata ) and the striped skunk ( mephitis mephitis ) as its intermediate and definitive hosts, respectively. here, we employed light microscopy, electron microscopy, and dna sequencing ... | 2010 | 20496959 |
| identification of sarcocystis rileyi from the mallard duck (anas platyrhynchos) in europe: cyst morphology and results of dna analysis. | macroscopic cysts of sarcocystis in ducks were recorded in europe, but they were not investigated in more detail. results of light and electron microscopy as well as 18s rdna, 28s rdna and its-1 region sequences of sarcocystis macrocysts isolated from naturally infected mallard duck (anas platyrhynchos) from lithuania are presented in this paper. according to ultrastructure results, macrocysts examined corresponds to s. rileyi. phylogenetic investigation showed s. rileyi to be the most closely r ... | 2010 | 20978794 |
| molecular characterisation of sarcocystis rileyi from a common eider (somateria mollissima) in norway. | the breast and leg muscles of a common eider (somateria mollissima; anatidae: anseriformes) from northern norway contained numerous grossly visible cigar-shaped sarcocysts measuring about 5 × 1 mm. light microscopic examination of isolated sarcocysts revealed that they were encapsulated by a thin fibrous layer, underneath which there was a thin and fairly smooth cyst wall with no visible protrusions. the cystozoites were straight, spindle-shaped and about 13 μm long. genomic dna was extracted fr ... | 2014 | 25082019 |
| detection and molecular identification of sarcocystis rileyi (apicomplexa: sarcocystidae) from a northern shoveler (anas clypeata) in mexico. | we detected macroscopic sarcocystis cysts in a northern shoveler ( anas clypeata ) in the lerma marshes, state of mexico, mexico in february 2014. the 5.0×2.0-mm macrocysts in the breast muscle of the duck were ovoid and yellow. using an optical microscope, we saw parasitic forms of a sarcocystis sp. among muscular fibers; the cysts measured 3.5×1.1 mm. the external wall had a smooth surface and the internal wall had a spongy texture. we identified the macrocysts as sarcocystis rileyi according ... | 2016 | 27537932 |
| molecular identification of sarcocystis rileyi sporocysts in red foxes (vulpes vulpes) and raccoon dogs (nyctereutes procyonoides) in lithuania. | despite the fact that sarcocystis rileyi is one of the earliest described species of the genus sarcocystis forming macrocysts in ducks, the life cycle of this species is still unknown in europe. sarcocystis spp. oocysts/sporocysts were observed in faeces of four of 23 (17.4 %) and in small intestine mucosal scrapings of four of 20 (20.0 %) red foxes (vulpes vulpes) and in small intestine mucosal scrapings of seven of 13 (53.8 %) raccoon dogs (nyctereutes procyonoides) hunted in lithuania. a very ... | 2015 | 25656464 |
| identification and intraspecific genetic diversity of sarcocystis rileyi from ducks, anas spp., in lithuania and finland. | 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 each ... | 2014 | 24766223 |
| parasites of waterfowl from southwest texas: ii. the shoveler, anas clypeata. | thirty-eight shoveler ducks, anas clypeata , were collected in the rio grande valley, hudspeth county, texas. nineteen species of helminths, six species of lice and a sarcosporidian, sarcocystis rileyi , were recorded. seventeen of the nineteen species of helminths were observed in fall migrants and twelve species were recorded from spring migrants. the nematode alifilaria pochardi ali, 1969, is a new host and american record. | 1977 | 24228969 |
