Morphological and molecular characterization of Sarcocystis taeniata and Sarcocystis pilosa n. sp. from the sika deer (Cervus nippon) in Lithuania.

The diaphragm muscles of eight sika deer (Cervus nippon) bred in Lithuania were examined for Sarcocystis cysts. Two Sarcocystis species, Sarcocystis taeniata, which were previously reported in Canadian moose (Alces alces) and Argentinean red deer (Cervus elaphus), and Sarcocystis pilosa n. sp.

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.

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.

Description of Sarcocystis lari sp. n. (Apicomplexa: Sarcocystidae) from the great black-backed gull, Larus marinus (Charadriiformes: Laridae), on the basis of cyst morphology and molecular data.

A morphological type of Sarcocystis cysts found in one of two examined great black-backed gull, Larus marinus (Linnaeus) (Laridae), is considered to represent a new species for which the name Sarcocystis lari sp. n. is proposed and its description is provided.

Molecular and morphological investigations of Sarcocystis corvusi sp. nov. from the jackdaw (Corvus monedula).

One type of sarcocyst was found in two of eight investigated jackdaws (Corvus monedula) and proposed as Sarcocystis corvusi sp. nov. By light microscope, cysts resembled a thick thread and were very long (the largest fragment found amounted to 6 mm) and relatively thin (up to 60 μm).

Description of Sarcocystis turdusi sp. nov. from the common blackbird (Turdus merula).

Cysts of Sarcocystis species were found in 24 of 44 (54·5%) examined blackbirds (Turdus merula). Under the light microscope, only 1 morphological type of cyst was found in all birds investigated. Ribbon-shaped cysts were long (the largest fragment found amounted to 7 mm) and of different thickness (25-206 μm).

Description of Sarcocystis anasi sp. nov. and Sarcocystis albifronsi sp. nov. in birds of the order Anseriformes.

On the basis of the already published morphological, 18S rDNA, 28S rDNA data (Kutkienė et al., Parasitol Res 99:562-565, 2006; Parasitol Res 102:691-696, 2008; Parasitol Res 104:329-336, 2009), and ITS-1 region investigation results of sarcocysts presented in this paper, Sarcocystis albifronsi sp. nov.

Sarcocystis sp. from the herring gull (Larus argentatus) identity to Sarcocystis wobeseri based on cyst morphology and DNA results.

Having studied 11 herring gulls (Larus argentatus) Sarcocystis cysts were found in neck and leg muscles of 4 birds. One type of sarcocysts (cyst type I) that have a thin (∼1.0 μm), smooth, or slightly wavy cyst wall without clearly visible protrusions and small (6.

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.

The mallard duck (Anas platyrhynchos) as intermediate host for Sarcocystis wobeseri sp. nov. from the barnacle goose (Branta leucopsis).

Morphometric and DNA investigation results of Sarcocystis wobeseri sp. nov. from the barnacle goose (Branta leucopsis) and Sarcocystis sp.

Sarcocystis in the birds family Corvidae with description of Sarcocystis cornixi sp. nov. from the hooded crow (Corvus cornix).

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.

Sarcocystis sp. from the goldeneye (Bucephala clangula) and the mallard (Anas platyrhynchos): cyst morphology and ribosomal DNA analysis.

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.

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.

Effect of lead and chromium on reproductive success of Japanese quail.

An experimental model based on application of Japanese quail (Coturnix coturnix japonica) lines with high (H) and low (L) concentrations of plasma lactate was designed in order to investigate the effects of lead and chromium on embryonic development and reproductive success of experimental groups representing different genotypes. During the first stage of the trial, mature males from quail lines H and L (marked as generation T) were fed subchronically for 12 weeks with lead as Pb(NO(3))(2) and chromium as K(2)Cr(2)O(7) (dosage 0.8 and 0.

Sarcocystis spp. in birds of the order Anseriformes.

Having studied 342 birds of 20 species of the order Anseriformes, we found Sarcocystis cysts in 100 individuals (29.2+/-2.5%) belonging to 15 species.
