Seroepidemiology of Sarcocystis neurona and Neospora spp. in Horses, Donkeys, and Mules from Colombia.

Acta Tropica, 2021
Sarcocystis neurona and Neospora spp. are related protozoa that can cause equine protozoal myeloencephalitis (EPM). The present study aimed to determine the frequency of antibodies to these parasites in 649 equids (351 horses, 267 donkeys, and 31 mules ...

Serosurvey of Toxoplasma gondii, Neospora caninum and Sarcocystis neurona in raptors and risk factor analysis.

Parasitology international, 2021
Raptors are carnivorous birds with great hunting ability. Toxoplasma gondii, Neospora caninum and Sarcocystis spp. are intracellular Apicomplexan protozoans which infect a wide range of intermediate hosts, including birds.

Structure of Sarcocystis neurona Sarcocysts

The Journal of Parasitology, 2001
The ultrastructure of Sarcocystis neurona sarcocysts was studied from muscle of an experimentally infected cat. The cat was killed 144 days after being fed sporocysts from a naturally infected opossum. Sarcocysts were microscopic, up to 700 microm long, and up to 50 microm wide.

Multiple DNA Markers Differentiate Sarcocystis neurona and Sarcocystis falcatula

The Journal of Parasitology, 1999
Studies designed to investigate the causative agent of equine protozoal myeloencephalitis and its life cycle have been hampered by the marked similarity of Sarcocystis neurona to other Sarcocystis spp. present in the same definitive host. Random-amplified polymorphic DNA techniques were used to amplify DNA from isolates of S.

Are Sarcocystis neurona and Sarcocystis falcatula Synonymous? A Horse Infection Challenge

The Journal of Parasitology, 1999
Equine protozoal myeloencephalitis (EPM) is a debilitating neurologic disease of the horse. The causative agent. Sarcocystis neurona, has been suggested to be synonymous with Sarcocystis falcatula, implying a role for birds as intermediate hosts. To test this hypothesis, opossums (Didelphis virginiana) were fed muscles containing S.

Sarcocystis neurona

2016
3.4. Evidence of S. neurona in fecal samples from sea lions 3.4.1. Cell culture and serological examination In an effort to propagate and isolate coccidian protozoa identified by light microscopy in sea lion feces, sporulated oocysts from CSL10089 (Coccidia A), CSL10092 (Coccidia A & B), CSL10100 (Coccidia A & B), and CSL10266 (Coccidia A) were ...

Ultrastructure of schizonts and merozoites of Sarcocystis neurona

Veterinary Parasitology, 2001
The ultrastructure of Sarcocystis neurona schizonts and merozoites was studied in specimens derived from cell culture and from the brains of infected mice. Schizonts and merozoites were located in the host cell cytoplasm without a parasitophorous vacuole at any stage of development. Merozoites divided by endopolygeny.

Characterization of monoclonal antibodies developed against Sarcocystis neurona

Parasitology Research, 2002
Equine protozoal myeloencephalitis (EPM), caused by a protozoal parasite infection of the central nervous system, is the most commonly diagnosed neurologic disease of horses in North America. In specific regions of the United States approximately 50% of the horse population is seropositive to Sarcocystis neurona.

Sarcocystis neurona subsp. shedding

2016
3.5. Evidence of S. neurona shedding by free-ranging sea lions In light of the unexpected findings revealed during cell culture analysis of fecal samples from stranded hospitalized sea lions, we screened all DNA extracted from frozen, pelleted oocysts of both hospitalized and field-collected fecal samples using S. neurona / S.

COMPLETION OF THE LIFE CYCLE OFSARCOCYSTIS NEURONA

Journal of Parasitology, 2000
Sarcocystis neurona is the most important cause of a neurologic disease in horses, equine protozoal myeloencephalitis (EPM). The complete life cycle of S. neurona, including the description of sarcocysts and intermediate hosts, has not been completed until now.
