Mieloencefalite protozoária equina (Sarcocystis neurona e Neospora hughesi): Revisão [PDF]

Pubvet, 2019
Equine Protozoal Mieloencephalitis is a disease that affects equines and asininos by the occurrence and formation of cysts in the spinal cord and central nervous system of merozoites of Sarcocystis neurona and Neospora hughesi. In general, horses are accidental intermediate hosts of S.

Canine and Bovine Neospora caninum Control Sera Examined for Cross-Reactivity Using Neospora caninum and Neospora hughesi Indirect Fluorescent Antibody Tests [PDF]

Journal of Parasitology, 2009
Neospora caninum is a well known protozoan parasite of domestic and wild animals. Neospora hughesi is a closely related protozoan with an unknown life cycle, host range, and infection prevalence. Many serologic surveys of N. caninum have been performed without consideration of potential cross-reactions with N. hughesi, which could confound results. The

Prevalence of antibodies toSarcocystis neuronaandNeospora hughesiin horses from Mexico [PDF]

Parasite, 2013
Equine protozoal myeloencephalitis (EPM) is a debilitating disease of horses caused by Sarcocystis neurona and Neospora hughesi. Sera from 495 horses in Durango State, Mexico were tested for anti-protozoal antibodies using enzyme-linked immunosorbent assays (ELISAs) based on major surface antigens of these two parasites. Antibodies to S.

Seroepidemiology ofSarcocystis neuronaandNeospora hughesiinfections 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. hughesi in donkeys in the northern Mexican state of Durango. Serum samples of 239 domestic donkeys (Equus asinus) were assayed for S. neurona and N.

Effects of Blood Contamination of Cerebrospinal Fluid on Results of Indirect Fluorescent Antibody Tests for Detection of Antibodies against Sarcocystis Neurona and Neospora Hughesi [PDF]

Journal of Veterinary Diagnostic Investigation, 2007
The purpose of this study was to determine the effect of blood contamination of cerebrospinal fluid (CSF) on the results of indirect fluorescent antibody tests (IFATs) for Sarcocystis neurona and Neospora hughesi. The in vitro study used antibody-negative CSF collected from non-neurologic horses immediately after euthanasia and blood samples from 40 ...

INVESTIGATION OF NEOSPORA HUGHESI ANTIBODIES BY USING ELISA IN HORSES IN NINEVEH PROVINCE [PDF]

Assiut Veterinary Medical Journal, 2014
The present study have been done from September 2013 to February 2014, on 90 horses of both sex and age at three different regions of Nineveh province - Iraq. Blood samples were collected from jugular vein of 90 horses, some animals appeared clinically healthy while others suffered from different clinical signs.

Neosporosis in Ontario broodmares: Seroprevalence and Risk Factors for Exposure to Neospora caninum and Neospora hughesi

, 2023
The seroprevalence and risk factors for exposure to Neospora caninum and Neospora hughesi in Ontario broodmares were investigated. The prevalence estimates for N. caninum and N. hughesi were 27.4% (60/219) and 29.7% (65/219), respectively. The IFAT cut-off titre for N. caninum and N. hughesi was 1:40 and 1:160, respectively. Risk factors for N. caninum

Neospora hughesi: experimental infections in mice, gerbils, and dogs

Veterinary Parasitology, 2000
Neospora hughesi is a recently described cause of equine protozoal myeloencephalitis (EPM). A rodent model for pathogenicity would facilitate development of therapies to be used in horses. In the present study, we examined the susceptibility of BALB/c gamma-interferon gene knockout (gamma-INFKO), BALB/c, CD-1, and C57BL/6 strains of mice and gerbils to

Differentiation of Neospora hughesi from Neospora caninum based on their immunodominant surface antigen, SAG1 and SRS2.

International journal for parasitology, 2000
Neospora hughesi is a newly recognised parasite that is closely related to Neospora caninum, and is a cause of equine protozoal myeloencephalitis. We have characterised two N. hughesi immunodominant tachyzoite antigens which exhibit antigenic and molecular differences from the homologous tachyzoite antigens on N. caninum. These antigens on N.

CHARACTERIZATION OF THE OREGON ISOLATE OFNEOSPORA HUGHESIFROM A HORSE

Journal of Parasitology, 2001
Neospora hughesi was isolated in cell cultures inoculated with homogenate of spinal cord from a horse in Oregon. Tachyzoites of this Oregon isolate of N. hughesi were maintained continuously by cell culture passage and tachyzoites were infective to immunosuppressed mice. Gamma interferon gene knockout (KO) mice injected with tachyzoites developed fatal
