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...

The milkweed, Calotropis gigantea (L.) W.T. Aiton (Gentianales: Asclepiadaceae) locally known as Akond, is an evergreen, perennial shrub, and is widely distributed in sub-tropical and tropical countries. It has been reported that latices of the milkweeds including C. gigantea contain cardiac glycosides that vary in amount and type between species, between various plant parts of the same species...

Chromosome numbers and 2C-values of six Byblis species were determined to investigate the chromosome differentiation genome diversity in this genus. Somatic B. liniflora complex showed diploid tetraploid 2n=16 32. In contrast, number gigantea, which belongs gigantea complex, displayed only 2n=36. The 2C DNA contents across all studied over a three-fold range, from lowest value 2C=0.64 pg rorida...

Background: Calotropis gigantea of family Asclepiadaceae, is traditionally used in ayurveda for its anti-helminthic, anti-pyretic, and anti-malarial activities. The present study was designed to investigate the sub-acute toxic effects of ethanol and methanol extract of Calotropis gigantea latex in mouse model using haematology, serum biochemistry and histopathological changes as toxicity indice...

Creeping bentgrass (Agrostis stolonifera) and redtop (A. gigantea) are introduced turfgrasses that are naturalized throughout the northern U.S. Interest in creeping bentgrass has risen following the 2003 escape of a genetically modified (GM), herbicide-resistant cultivar near Madras, Oregon. The objectives of this study were to characterize the floristic attributes of the plant communities asso...

A motivational model of alcohol involvement (M. L. Cooper, M. R. Frone, M. Russell, & P. Mudar, 1995) was replicated and extended by incorporating social antecedents and motives and by testing this model cross-sectionally and longitudinally in a sample of college students. Participants (N = 388) completed a questionnaire battery assessing alcohol use and problems, alcohol expectancies, sensatio...

Sarcocystis species are intracellular protozoan parasites with an intermediate-definitive host life cycle based on a prey-predator relationship. Asexual stages develop in intermediate hosts after they ingest the oocyst stage from definitive-host feces and terminate with the formation of intramuscular cysts (sarcocysts). Sarcocysts in meat eaten by a definitive host initiate sexual stages in the...

Sarcocystis speeri Dubey and Lindsay, 1999 from the South American opossum Didelphis albiventris was successfully transmitted to the North American opossum Didelphis virginiana. Sporocysts from a naturally infected D. albiventris from Argentina were fed to 2 gamma-interferon knockout (KO) mice. The mice were killed 64 and 71 days after sporocyst feeding (DAF). Muscles containing sarcocysts from...

The North American opossum, Didelphis virginiana, is a definitive host for at least 3 species of Sarcocvstis: S. falcatula Stiles 1983, S. neurona Dubey, Davis, Speer, Bowman, de Lahunta, Granstrom, Topper, Hamir, Cummings, Suter 1991, and S. speeri Dubey and Lindsay 1999. In order to identify species of Sarcocystis in the South American opossum, D. inarsupialis, Sarcocystis sporocysts from the...
