Genetic resistance to Sarcocystis miescheriana in pigs following experimental infection.
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...
متن کاملMapping of quantitative trait loci affecting resistance/susceptibility to Sarcocystis miescheriana in swine.
The outcome of infectious diseases in vertebrates is under genetic control at least to some extent. In swine, e.g., marked differences in resistance/susceptibility to Sarcocystis miescheriana have been shown between Chinese Meishan and European Pietrain pigs, and these differences are associated with high heritabilities. A first step toward the identification of genes and polymorphisms causal f...
متن کاملSarcocystis spp. in human infections.
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...
متن کاملEffects of genetic variation on total plasma protein, body weight gains, and body temperature responses to heat stress.
The effects of heat stress (HS) on total plasma protein (PP) concentrations, body weight gains (BWG), and body temperature (BT) were studied in an Athens-Canadian Randombred (ACRB) population and commercial broilers (BR). The populations were maintained at environmental temperatures of 21, 32, and 38 C from 3 to 6 wk of age. The PP, BWG, and mortality (M) were measured at 3, 4, 5, and 6 wk and ...
متن کاملMolecular diagnostics of Sarcocystis spp. infections.
Protozoa of the genus Sarcocystis (phylum Apicomplexa, family Sarcocystidae) is one of the most common parasites affecting animals. Interspecies diagnostic of Sarcocystis genus was based on electron microscopy for many years. Because of absence of visible differences between species with reachable magnifications, light microscopy is useless. In many cases serological diagnostic method have lack...
