“…Our previous studies (Kutkienė and Sruoga 2004), as well as studies of the recent years, showed that infection of white-fronted geese with Sarcocystis spp. is high; parasites have been found in 89 (61.8±4.0%) individuals out of the 144 examined ones.…”

“…Though several types of Sarcocystis cysts have been recorded in ducks (Drouin and Mahrt 1980;Kutkienė and Sruoga 2004), only one species-Sarcocystis rileyi-whose definitive host is a skunk in North America, has been described at length (Dubey et al 2003). According to the morphological features, this species is found in Europe too (Kutkienė and Sruoga 2004); however, its definitive host is unknown on this continent. Little is known about the Sarcocystis spp.…”

Sarcocystis sp. from white-fronted goose (Anser albifrons): cyst morphology and life cycle studies

An experiment was carried out using three cubs of the arctic fox (Alopex lagopus). Twenty-five-day-old cubs were infected by feeding them with the leg muscles of the white-fronted goose (Anser albifrons) containing Sarcocystis sp. (cyst type III) cysts. Under the light microscope, the cysts were ribbon-shaped up to 4 mm long and up to 750 microm wide. On the surface of the wall (up to 2.4 microm), they had teat- or finger-like villar protrusions. Ultrastructurally, the cyst wall was a type-9 with villar protrusions (up to 2.3 microm long) different in size. The 11.4x1.7 (10.0-13.5x1.5-2.5)microm cystozoites were almost straight and shuttle-shaped. The fox cubs started shedding typical 12.0x8.0 (10.0-12.8x6.8-8.6)microm Sarcocystis sp. sporocysts on the 13th-14th days post-infection. The patent period lasted 19 days. The conclusion drawn was that the arctic fox (A. lagopus) can be one of the definitive hosts of Sarcocystis sp. (cyst type III) from the white-fronted goose.

By light microscopy, cysts of Sarcocystis sp. (cyst type I) from the goldeneye (Bucephala clangula) seemed filamentous with a smooth and thin (<1 microm) cyst wall. Ultrastructurally, the cyst wall surface was irregular with minute undulations of the primary cyst wall. These sarcocysts had type-1 cyst wall. Cystozoites were banana-shaped and measured 7.0-8.5 microm in length. By light microscopy, cysts of Sarcocystis sp. (cyst type II) from the mallard (Anas platyrhynchos) were ribbon-shaped, very long, and thin. On the surface of the wall (up to 1.5 microm), they had palisade-like villar protrusions closely crowded together. Electron micrographs showed villar protrusions (up to 1.3 microm in length) different in size and shape. The latter had short microprojections especially obvious in the oblique sections. Cystozoites were slightly bent with blunt ends, broader at one end, and measured 13.0-16.1 x 1.8-2.5 microm. Phylogenetic analysis based on the comparison of partial 28S rRNR gene sequences of Sarcocystis sp. (cyst type II) derived from the mallard, Sarcocystis sp. (cyst type I) and Sarcocystis sp. (cyst type III) both derived from the white-fronted goose (Anser albifrons) suggested that these sequences belonged to separate Sarcocystis species.

Having studied 67 birds of six species of the family Corvidae, Sarcocystis cysts were found in 16 (23.9%) individuals belonging to three species. The highest prevalence of infection (35.9%) was determined in the hooded crow (Corvus cornix). Two types of sarcocysts, which were temporarily called cysts type I and type V, were determined in the corvids examined. By light microscope, type I cyst wall seemed to be thin (< 1.0 microm) and smooth. Banana shaped cystozoites measured 6.0-8.0 microm in length. By light microscope, type V cyst wall seemed striated and reached up to 2.5 microm. Banana shaped cystozoites measured 6.1-7.9 x 1.4-1.8 microm. Ultrastructurally, the cyst wall amounted to 2.1 microm and had stump-like protrusions that differed greatly in size and shape. The parasitophorous vacuolar membrane had indentations and clearly visible (up to 0.2 microm in length) microprojections, which also differed considerably in size and shape. The ultrastructure of type V cyst wall differed from all those Sarcocystis spp. described thus far. On the basis of this-Sarcocystis cornixi sp. nov.-is proposed for this type of sarcocysts. Partial sequences of 18S rRNA and 28S rRNA genes were determined for this species and a phylogenetic analysis of the Sarcocystidae family was performed. In the phylogenetic tree, S. cornixi is grouped together with Frenkelia microti, F. glareoli, S. muris, S. neurona and the unnamed Sarcocystis species whose intermediate hosts are birds. S. cornixi is the most closely related to Sarcocystis sp. (cyst type I) from the white-fronted geese.
