EPM more widespread than expected among US horses – study
A recent report past times American researchers reveals that equine protozoal myeloencephalitis (EPM), caused past times 2 unlike parasites, is widespread throughout the United States.
The single-celled protozoal parasite Sarcocystis neurona, which is shed inward the feces of opossums, is the most usually recognized motility of this neurological illness inward horses.
However, this report past times researchers at the University of California, Davis School of Veterinary Medicine institute evidence that Neospora hughesi, the other EPM-causing parasite, start identified inward California, is straightaway existence identified inward horses across the United States.
After obtaining a total of 3123 diagnostic submissions from 49 states, UC Davis determined that horses from 42 states were affected past times parasites causing EPM.
Horses inward 24 states tested positive for antibodies against Neospora hughesi together with Sarcocystis neurona. Horses from 17 states tested positive for antibodies against Sarcocystis neurona only, piece horses inward ane state tested positive for antibodies against Neospora hughesi only.
The researchers said that, because these results showed a widespread distribution of the parasites causing EPM, Equus caballus owners together with practitioners should exam horses suspected of having EPM for antibodies against both parasites.
“This report returned positive results from to a greater extent than states than nosotros originally thought,” said D. Nicola Pusterla, Pb researcher on the study.
“As the recognized geographic spread of Neospora hughesi infections expands, nosotros are encouraging Equus caballus owners most the benefits of the advanced tests available at UC Davis to to a greater extent than accurately diagnose the disease.
“Overall, nosotros had non been satisfied alongside the criterion testing available, together with hence nosotros convey spent the past times decade developing together with successfully validating an improved diagnostic tool for EPM.”
The SarcoFluor together with NeoFluor tests created past times UC Davis are immunofluorescent antibody tests for both of the known causative agents of EPM (Sarcocystis neurona together with Neospora hughesi).
These tests render a quantitative indication of EPM infection together with render greater sensitivity together with specificity than the Western immunoblot exam on serum samples, the researchers say.
UC Davis’ tests also trim down the necessity to obtain cerebrospinal fluid inward club to concealment for antibodies against the 2 protozoal agents.
Dr Patricia Conrad, professor together with caput of the laboratory at UC Davis that developed the tests, said clinicians together with scientists had used the resources available at UC Davis to validate the novel tests.
Dr Claudia Sonder, managing director of the Center for Equine Health at UC Davis, said: “Since its regain inward horses, EPM has posed a pregnant diagnostic together with therapeutic challenge.
For the start time, she said, veterinarians tin associate probability of EPM infection alongside positive tests results, together with tin dominion out both organisms known to motility EPM alongside negative tests.
“This advancement inward diagnostic capability is much welcomed past times all faced alongside this complicated disease.”
The tests are available through the laboratory services at the UC Davis Veterinary Medical Teaching Hospital. For to a greater extent than information, contact VMTH laboratory services at 530-752-VMTH or instruct online here.
