Reactivity against Sarcocystis neurona and Sarcocystis falcatula-like in horses from Southeastern and Midwestern Brazil [PDF]

Revista Brasileira de Parasitologia Veterinária, 2023
Equine protozoal myeloencephalitis (EPM) is a neurological disease caused by Sarcocystis neurona. Immunofluorescence antibody tests (IFATs) have been widely used to identify exposure of horses to S. neurona in Brazil.

Reactivity of Horse Sera to Antigens Derived From Sarcocystis falcatula–Like and Sarcocystis neurona [PDF]

Frontiers in Veterinary Science, 2020
Sarcocystis neurona and Sarcocystis falcatula are protozoan parasites endemic to the Americas. The former is the major cause of equine protozoal myeloencephalitis, and the latter is associated with pulmonary sarcocystosis in birds.

Systems-Based Analysis of the Sarcocystis neurona Genome Identifies Pathways That Contribute to a Heteroxenous Life Cycle [PDF]

mBio, 2015
Sarcocystis neurona is a member of the coccidia, a clade of single-celled parasites of medical and veterinary importance including Eimeria, Sarcocystis, Neospora, and Toxoplasma.

High-throughput screen of drug repurposing library identifies inhibitors of Sarcocystis neurona growth [PDF]

International Journal for Parasitology: Drugs and Drug Resistance, 2018
The apicomplexan parasite Sarcocystis neurona is the primary etiologic agent of equine protozoal myeloencephalitis (EPM), a serious neurologic disease of horses. Many horses in the U.S.

Transcriptional dynamics in the protozoan parasite Sarcocystis neurona and mammalian host cells after treatment with a specific inhibitor of apicomplexan mRNA polyadenylation [PDF]

PLoS ONE, 2021
In recent years, a class of chemical compounds (benzoxaboroles) that are active against a range of parasites has been shown to target mRNA polyadenylation by inhibiting the activity of CPSF73, the endonucleolytic core of the eukaryotic polyadenylation ...

Temporal gene expression during asexual development of the apicomplexan Sarcocystis neurona [PDF]

mSphere
Asexual replication in the apicomplexan Sarcocystis neurona involves two main developmental stages: the motile extracellular merozoite and the sessile intracellular schizont.

Parasite genotype is a risk factor for Sarcocystis neurona-associated mortality in southern sea otters (Enhydra lutris nereis) [PDF]

International Journal for Parasitology: Parasites and Wildlife
The protozoal parasites Sarcocystis neurona and Toxoplasma gondii are important causes of mortality for threatened southern sea otters (Enhydra lutris nereis) in California. Sarcocystis neurona causes more sea otter deaths than T.

Spatial epidemiological patterns suggest mechanisms of land-sea transmission for Sarcocystis neurona in a coastal marine mammal. [PDF]

Sci Rep, 2020
Sarcocystis neurona was recognised as an important cause of mortality in southern sea otters (Enhydra lutris nereis) after an outbreak in April 2004 and has since been detected in many marine mammal species in the Northeast Pacific Ocean.

Sarcocystis neurona Transmission from Opossums to Marine Mammals in the Pacific Northwest. [PDF]

Ecohealth, 2021
Increasing reports of marine mammal deaths have been attributed to the parasite Sarcocystis neurona. Infected opossums, the only known definitive hosts, shed S. neurona sporocysts in their feces.

Seroepidemiology of Sarcocystis neurona and Neospora hughesi infections in domestic donkeys (Equus asinus) in Durango, Mexico [PDF]

Parasite, 2017
There is currently no information regarding Sarcocystis neurona and Neospora hughesi infections in donkeys in Mexico. Here, we determined the presence of antibodies against S. neurona and N.
