Equine Herpesvirus Infections (EHV-l, EHV-2, EHV-3, EHV-4)

HSI would like to encourage stallion and mare owners to follow the voluntary guidelines outlined in this Code of Practice in order to minimise the incidence of infectious diseases in the Irish Sport Horse sector. What are the signs of infection? Divers, DVM, Dipl. But for many years, veterinarians were faced with subpar testing options when it came to diagnosing Lyme disease in horses. This is the result of the spread of the Equine Herpes Virus. Recovered horses become chronic carriers without clinical signs. In this study, 139 horses with colic and 139 control horses were evaluated for the presence of tapeworm antibodies.

Further, with only three FDA-approved treatment options, treating EPM can be a challenge as well. The virus is not transmissible to humans. While they can’t produce a perfect report stating that your horse has disease X and needs treatment Y, the various numbers, shapes, and sizes of the blood components can tell the clinician the horse is possibly anemic, losing blood, or fighting an infection or an immune-mediated disease. In this special collection of three articles this month, we will delve into the often-contentious world of EPM research to share what practitioners and those studying the disease have discovered. It occurs naturally in parts of Africa, Asia, the Middle East, Europe, North America, Central America, Caribbean Islands, and South America. If two specimen types are submitted for EPM, the second test will be billed at an additional price. So, this begs the question: When dealing with a potentially deadly mosquito-borne disease, such as Eastern equine encephalomyelitis (EEE) or West Nile virus (WNV), how do you tell the difference between a horse that’s been vaccinated and one that’s truly infected?


According to Jeremy Howard, sales manager at BioTracking, breeders and veterinarians can draw blood from mares and send samples to BioTracking’s lab. Turn around times are average or minimum days required for test completion. Here, glycoprotein D of EHV-1 was expressed by a recombinant baculovirus, purified and evaluated by a simple agar gel immunodiffusion test (AGID). And recently, a biomarker called SAA has become such a word, garnering attention from the equine veterinary community for its ability to indicate inflammation. Kenneth L. Veterinarians often detect a GCT during a routine palpation or rectal ultrasound, and currently veterinarians rely on endocrine tests–measuring blood levels of certain hormones such as inhibin, testosterone, and progesterone–to confirm suspicions of a GCT. One such disease is pituitary pars intermedia dysfunction (PPID), also referred to as equine Cushing’s disease.

Twenty-five years ago we became aware of an enigmatic parasitic infection of the nervous system of the horse. A 409 base pair segment obtained as PCR amplification product in 9 samples was digested with Hae III to confirm the presence of EHV-1 as the infectious agent in aborted tissues. The EDCC said that on Jan. In some cases, the reason for the loss of performance is quite obvious–the horse is lame with a swollen joint; he developed exertional rhabdomyolysis (tying-up); or there is an abnormal discharge from both nostrils, suggesting a respiratory problem. There are 34 other equids (including horses, Miniature Horses, and miniature donkeys) on this premises that are under quarantine. Equine protozoal myeloencephalitis (EPM) is one of the most challenging and exasperating diseases in horses, not only for veterinary scientists but for horse owners as well. It isn’t that the blood test will necessarily pinpoint the malady from which the horse is suffering, but, when added to other circumstantial evidence, it makes a highly important contribution to the diagnosis.

Equine infectious anemia virus (EIAV) is a member of the genus Lentivirus of the family Retroviridae. Belgian researchers recently determined that some standard laboratory and commercial allergy tests for horses are not reliable—often suggesting allergies that don’t exist. For cases involving insurance claims or litigation, contact the laboratory for instructions prior to submitting. In the eight virus-infected cases the immunostaining revealed foci of cells exhibiting a distinct brown cytoplasmic and inclusion body pigmentation. Because tapeworm infestations are difficult to detect in feces, veterinarians’ preferred testing method has been blood testing. Since the presence of Equine Herpesvirus Myeloencephalopathy, or EHM, was confirmed Monday, about 180 horses have been quarantined in the building known as the red barn. Clinical manifestation of the disease is variable and often includes icterus (jaundice), haemoglobinuria and fever.

A board certified surgeon, Rashmir-Raven has an interest in equine lameness and helping keep older equine athletes comfortable and competitive. Is it really that important? Email Fonner Park in Grand Island, Neb., has closed its backstretch as it awaits blood tests on horses who have displayed symptoms consistent with the equine herpesvirus, the highly contagious disease that has led to quarantines at racetracks across the U.S. The Cornell AHDC is now offering real-time PCR based Equine and Canine Respiratory Panels to aid veterinarians in rapidly identifying the presence of common disease agents in dogs and horses with acute respiratory illness.
