Clinical and parasitological traits of Sarcocystis miescheriana differ in Pietrain and Meishan pigs. For further description and characterization of the genetic basis of this variation a F(2) family based on Pietrain boars and Meishan sows as founders was generated. One hundred and thirty-nine F(2) pigs were challenged orally at an age of 100 days with 50,000 sporozysts to produce the typical c...

background: sarcocystis infection is one of the most common zoonotic protozoon diseases caused by different sarcocystis spp. objectives: due to the importance of this infection in public health, the infection rate of macroscopic and microscopic cysts in sheep and cattle of abattoir of shahriar, was investigated. methods: 138 slaughtered sheep and cattle were selected randomly and their esophagu...

Understanding the role of disease in population regulation is important to the conservation of wildlife. We evaluated the prevalence of Toxoplasma gondii exposure and Sarcocystis spp. infection in 46 road-killed and accidentally trapper-killed fisher (Martes pennanti) carcasses collected and stored at -20 C by the Pennsylvania Game Commission from February 2002 to October 2008. Blood samples we...

We examined Sarcocystis spp. in giant snakes from the Indo-Australian Archipelago and Australia using a combination of morphological (size of sporocyst) and molecular analyses. We amplified by PCR nuclear 18S rDNA from single sporocysts in order to detect mixed infections and unequivocally assign the retrieved sequences to the corresponding parasite stage. Sarcocystis infection was generally hi...

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...

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...

Introduction: Hamburger is a popular type of fast foods consumed all over the world. Sarcocystis spp. is a zoonotic parasitic pathogen which endangers safety of meat and meat products. The present study describes the prevalence rate of Sarcocystis spp. in hamburgers in Yazd, Iran using PCR-RFLP. Materials and methods: Raw hamburger samples (100 traditional and 90 industrial) from central re...

Sarcocystis is an obligatory intracellular protozoan parasite which can infect humans and animals. Sheep are intermediate hosts of four Sarcocystis species: Sarcocystis tenella, Sarcocystis gigantea, Sarcocystis arieticanis, and Sarcocystis medusiformision. The purpose of the study was to determine the molecular identification of the macroscopic and microscopic cysts of Sarcocystis in sh...

Sarcocystis neurona is the most common cause of Equine Protozoal Myeloencephalitis (EPM), affecting 0.5-1% horses in the United States during their lifetimes. The objective of this study was to evaluate the equine immune responses in an experimentally induced Sarcocystis neurona infection model. Neurologic parameters were recorded prior to and throughout the 70-day study by blinded investigator...
