The different genera currently classified into the family Sarcocystidae include parasites which are of significant medical, veterinary and economic importance. The genus Sarcocystis is the largest within the family Sarcocystidae and consists of species which infect a broad range of animals including mammals, birds and reptiles. Frenkelia, another genus within this family, consists of parasites ...

Red deer (Cervus elaphus) from a National Wildlife Reserve near Toledo in central Spain were surveyed for Sarcocystis infection. A total of 61 deer were examined. Tissue compression and histology were used to examine samples from diaphragm and heart from each animal included in the study, and results from the two techniques and the two tissues were compared to determine the tissue and technique...

A study was designed to develop an experimental model to produce Sarcocystis neurona encephalitis in horses. Sarcocystis neurona, isolated from the spinal cord of an ataxic horse, was placed in continuous culture using bovine turbinate cells, and the cultured S. neurona merozoites were used to infect lymphocytes. A horse that was subsequently experimentally infected with 100,000 of the S. neuro...

Seven members of a 15-man U.S. military team that had operated in rural Malaysia developed an acute illness consisting of fever, myalgias, bronchospasm, fleeting pruritic rashes, transient lymphadenopathy, and subcutaneous nodules associated with eosinophilia, elevated erythrocyte sedimentation rate, and elevated levels of muscle creatinine kinase. Sarcocysts of an unidentified Sarcocystis spec...

Cowbirds (Molothrus ater) and grackles (Cassidix mexicanus) infected with muscle cysts of Sarcocystis were fed to opposums (Didelphis virginiana) and fecal sporocysts from the latter were given to sparrows (Passer domesticus, Family Ploceidae), canaries (Serinus canarius, Family Fringillidae) and ducks (Anas platyrhynchos, Family Anatidae). Asexual parasites were found in the endothelium of spa...

In January 1998 and 1999, two mass strandings of dolphins occurred in Wellfleet, Massachusetts. The strandings were composed of 97 and 53 animals, respectively. Tissues from 35 Atlantic white-sided dolphins (Lagenorhynchus acutus) from the 1998 stranding and 52 from the 1999 stranding were examined histologically. In the 1998 stranding, unidentified protozoal tissue cysts were seen in skeletal ...

Sarcocystis neurona are apicomplexan parasites that can cause mortality in domestic and wild animals. Twelve antigen types are described for S. neurona, however just two phenotypes (SnSAG 1 and SnSAG 5) represent the majority of those that are associated with disease. A novel S. falcatula gene, antigenically indistinct from SnSAG 6, was cloned into an expression vector and the recombinant prote...

background: sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of sarcocystis genus. the major aim of this study was to determine the prevalence of sarcocystis spp. in meat produced in yazd, central iran with special reference to species identification, using polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp).  method...
