Researchers discover protein that could improve strangles testing in horses
Reported by Phys.org · November 12 at 1:10 PM · Summary by Hoofdeck
Researchers at Texas A&M's College of Veterinary Medicine and Biomedical Sciences have identified a protein, called P92, that may help detect antibodies against the bacterium that causes strangles in horses. Their findings were published in the Journal of the American Veterinary Medical Association. The work targets the limits of the blood test most often used in the United States.
Background
Strangles is a contagious respiratory infection caused by Streptococcus equi subspecies equi, spreading mainly through nasal discharge and contaminated surfaces or equipment. Serological tests look for antibodies in blood serum, which can show past exposure when a sample from the infection site is hard to collect. Such tests can produce false results because related bacteria can trigger similar antibodies, so new markers are tested against established methods before wider use.
Why it matters
Accurate testing helps owners and veterinarians know whether a horse has been exposed, which guides isolation, quarantine and decisions about travel or breeding.
What you can do
If you have a horse with nasal discharge or swollen glands under the jaw, call your veterinarian for an exam and testing. Ask your vet about current strangles testing options before moving horses after any exposure.
