Abstract

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. The opossum Didelphis virginiana is the definitive host of these...

Abstract

Sarcocystis neurona, a coccidian parasite shed by opossums (Didelphis spp.) in the Americas, is the major cause of equine protozoal myeloencephalitis (EPM) and induces disease in other domestic and wild animal species, including domestic dogs. Sarcocystis cruzi, despite its low pathogenicity for...

Abstract

The aim of this study was to determine if bi-weekly administration of diclazuril at half the label dose would reduce seroprevalence and magnitude of titers to S. neurona in healthy horses naturally exposed to the apicomplexan protozoal parasite. 12 healthy adult horses were moved from a low-risk...

Abstract

Sarcocystis neurona is the major cause of the equine protozoal myeloencephalitis (EPM) in the Americas and has opossums of the genus Didelphis as definitive hosts. Most isolates of Sarcocystis sp. shed by opossums in Brazil differ genetically from the known species of Sarcocystis. These Brazilian...

Abstract

An ante-mortem diagnosis of equine protozoal myeloencephalitis (EPM) is presently based on clinical presentation, immunodiagnostics performed on serum and cerebrospinal fluid (CSF), and ruling out other neurological disorders. Molecular techniques introduce a novel and promising approach for the...

Abstract

Samples of 303 horses from 56 ranches of Rorainópolis municipality, state of Roraima, were evaluated by means of the Indirect Immunofluorescence Test (IFAT) to detect antibodies against Sarcocystis spp., Toxoplasma gondii and Neospora spp. A subset of positive sample (n=15) against Sarcocystis spp. ...

Abstract

Equine protozoal myeloencephalitis (EPM) is an important neurologic disease of horses in the American continent caused by Sarcocystis neurona and Neospora hughesi infection. This study describes the pathological, immunohistochemical, and molecular findings of fatal cases of EPM in southern Brazil....

Abstract

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) from six departments in the North and...

Abstract

Sarcocystis neurona is the main agent associated with equine protozoal myeloencephalitis (EPM). Apart from horses, S. neurona has been occasionally described causing neurologic disease in several other terrestrial animals as well as mortality in marine mammals. Herein, we describe the clinical,...
