introduction: the main agents of sarcocystosis in cattle as an intermediate host include s. cruzi, s. hominis and s. hirsuta. a sensitive and specific tool such as molecular-based techniques would be necessary to identify the species. case report: after collection of beef sample from yazd slaughterhouse, dna extraction was done with salting out method. the 18srrna gene as a specific target gene...

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, i...

there is considerable confusion concerning the structure and synonymity of macroscopic sarcocysts in goats. in the present work, ultrastructural and molecular study on fat and thin macrocysts of sarcocystis isolated from naturally infected goats were investigated. two forms of macrocystic sarcocysts were collected from fresh oesophagus, diaphragm, skeletal muscles and heart of slaughtered goats...

Monoclonal antibodies were raised against cystozoites of Sarcocystis muris and characterised. Twelve monoclonal antibodies reacted in the ELISA, Dot-ELISA and IFAT only with homologous antigen. The other twelve showed cross reactions of various degrees with cystozoites of S. gigantea, S. tenella, S. arieticanis, S. capracanis, S. miescheriana and S. suihominis. Proteins of S. arieticanis, S. te...

Dne hundred and seventy five passerine birds from the Czech Republic were examined for the presence of sarcosporidia; auly 5 (all great tits) were positive for muscle cysts. Three great tits experimentally fed sporocysts (12.2 x 8.4, 11-13x 7.5-9 !lm) from a goshawk developed cysts while 2 house sparrows (Passer domesticus) were not infected. The cysts from great tits muscles were morphological...
