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.

Penetration of equine leukocytes by merozoites of Sarcocystis neurona

Veterinary Parasitology, 2006
Horses are considered accidental hosts for Sarcocystis neurona and they often develop severe neurological disease when infected with this parasite. Schizont stages develop in the central nervous system (CNS) and cause the neurological lesions associated with equine protozoal myeloencephalitis.

Viability of Sarcocystis neurona sporocysts after long-term storage

Veterinary Parasitology, 2004
The effect of long-term storage on the viability and infectivity of Sarcocystis neurona sporocysts was investigated. S. neurona sporocysts were harvested from the small intestine of Virginia opossums from 1996 to 2002 and stored at 4 degrees C. Viability of sporocysts was assessed by propidium iodide (PI) exclusion assay, in vitro excystation and ...

Clinical Sarcocystis neurona, Sarcocystis canis, Toxoplasma gondii, and Neospora caninum infections in dogs

Veterinary Parasitology, 2006
Sarcocystis neurona, Sarcocystis canis, Toxoplasma gondii, and Neospora caninum are related apicomplexans that can cause systemic illness in many species of animals, including dogs. We investigated one breeder's 25 Basset Hounds for these infections. In addition, tissues from dogs and other non-canine hosts previously reported as S.

Molecular genetic transfection of the coccidian parasite Sarcocystis neurona

Molecular and Biochemical Parasitology, 2006
Sarcocystis neurona is an apicomplexan parasite that is the major cause of equine protozoal myeloencephalitis (EPM). The biology of this pathogen remains poorly understood in part due to unavailability of molecular genetic tools. Hence, with an objective to develop DNA transfection capabilities for S.
