screening of seropositive sarcocystis (apicomplexa: sarcocystidae, lankester1882) in sheep using counterimmunoelectrophoresis

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 exper...

A new species of Sarcocystis (Apicomplexa: Sarcocystidae) from the black bear (Ursus americanus).

Infection with Sarcocystis species is common in herbivores but is rare in bears. Histological sections of 374 black bears (Ursus americanus) from Pennsylvania were examined for sarcocysts. In total, 3 sarcocysts were found in 3 bears, with 1 sarcocyst per section. Sarcocysts from 2 bears were considered a new species, Sarcocystis ursusi. Sarcocysts of S. ursusi n. sp. were microscopic and conta...

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 defin...

First Molecular Identification of Sarcocystis ovicanis (Protozoa, Apicomplexa) in the Brain of Sheep in Iran

BACKGROUND The objective of the present study was to survey the presence of Sarcocystis in sheep's brain in North Khorasan Province. METHODS In general, 80 samples of sheep's brain were collected from slaughtered sheep in slaughterhouses of North Khorasan Province. Tissue digestion method was used for observing bradyzoites in tissues. Histopathological processing tracing Sarcocystis and ensui...
