Detection of antibodies against Sarcocystis neurona, Neospora spp., and Toxoplasma gondii in horses from Costa Rica.
Serum samples from 315 horses from Costa Rica, Central America, were examined for the presence of antibodies against Sarcocystis neurona, Neospora spp., and Toxoplasma gondii by using the surface antigen (SAG) SnSAG2 enzyme-linked immunosorbent assay (ELISA), the NhSAG1 ELISA, and the modified agglutination test, respectively. Anti- S. neurona antibodies were found in 42.2% of the horses by usi...
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 کاملResponse of Horses Exposed to Sarcocystis neurona When Monitored Biweekly
The incubation period of equine protozoal myeloencephalitis may be highly variable and horses may not always develop clinical signs after confirmed exposure. Horses appear to require other risk factors in addition to exposure to Sarcocystis neurona in order to develop clinical signs. Repeated exposures may be protective. Authors’ addresses: College of Veterinary Medicine, Depts. of Veterinary P...
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...
متن کاملExposure to Gasterophilus spp. in horses in NW Spain by ELISA
Gasterophilosis is a myiasis related with gastric ulcers in equids and even colics. A serological survey to assess the presence of IgG antibodies against Gasterophilus spp. in horses from an oceanic climate area was conducted. A total of 672 blood samples were analyzed by an enzyme-linked immunosorbent assay (ELISA) and excretory/secretory antigens from G. intestinalis second-instar larvae. Res...
