Dozens Of Horses Quarantined At Parx After Equine Herpes Outbreak

While there are several vaccines available for protection against both respiratory disease and abortion as a result of EHV-1 infection, at this time there is no equine licensed vaccine that has a label claim for protection against the neurological strain of the virus (EHM). There have been no neurologic abnormalities seen. Horses, cattle and coyotes were seronegative in one U.S. Serology is also useful; a rise in titer or the presence of specific IgM is diagnostic. The dog was suffering from an immune-mediated disease. For more information, readers may contact Dr. Do not use modified-live-virus vaccines in horses.

New blogs by owners will be posted on the first and 15th of each month. is an equine epidemiologist in Surveillance, Preparedness, and Response Services with USDA-APHIS. Equestrian Sport Productions states the two horses tested for EHV-1 that were located in the FEI Stabling at Palm Beach International Equestrian Center came back negative. Twenty-five of the 28 (89%) horses were diagnosed as WNV-positive on the basis of serological testing. The single radial hemolysis (SRH) test was validated in our laboratory to assess the level of antibodies to equine influenza virus on the paired serum samples collected. A total of 47 clinically healthy horses from Cornell equine research herds were included in the study (Table 1).

M. Horses may be partially protected frominsects if repellant is used. Since body temperature measurements had not started before day 5 of the outbreak, we assume that fever was missed in several horses in the beginning. The 2015 survey was limited to those who currently own or manage at least one horse, are 18 years of age or older and live in the United States. “This is no longer the disease of just 2- and 3-year-old racehorses,” explained Vaala, referring to the long-held horse industry belief that EIV is primarily a young-horse disease associated with related competitions, sales, transport stress, and/or lack of vaccination. Birds can ingest the toxins in maggots that have fed on contaminated carcasses or in dead invertebrates from water with decaying vegetation. The absence of nonspecific binding of the secondary antibody was also evaluated by omitting the primary antibody.

Yes, pet pigs are susceptible to H1N1; however it is not likely that you will get it from your pet pig. These locations were placed under quarantine due to high risk contact with Sweet Dreams Farm or having received a horse from Sweet Dreams. Mares who abort usually require no specific treatment unless symptomatic or if injury has occurred during parturition. Non-thoroughbreds: Saddle horses: Côtes d’Armor, Haute-Garonne, Nord, Seine-et-Marne (in 2 different stables), Yvelines. Recent outbreaks that have caused concern involve the respiratory/neurologic form. We require site users to register with Mondaq (and its affiliate sites) to view the free information on the site. Breeds affected have included Thoroughbreds (four), French Trotter (one), Perchercon (one) and French Saddlebred (one).

There are currently no antiviral drugs known to specifically treat equine herpes type 1 and type 4 infections. The most severely affected tissues correspond with the symptoms mentioned above. EHV-1 is easily spread by nose-to-nose or close contact with an infectious horse, by sharing contaminated equipment (bits, buckets, towels etc.) or by the clothing, hands or equipment of people who recently had contact with an infectious horse. Respiratory transmission of EVA occurs rapidly at horseshows, racetracks, and other locations where horses may come together in large numbers. In 2014, there was one laboratory-confirmed case of EHM in Ontario due to the non-neuropathogenic strain. Stallions who become carriers may spread the virus during natural breeding or through artificial insemination (AI) techniques with EVA positive semen. The clinical signs of WNV can be consistent with other important neurologic diseases such as equine encephalitis, rabies, and equine herpesvirus; therefore it is important to work with your veterinarian to get an accurate diagnosis through laboratory testing.

Virus isolation tests were also negative. Rhodococcal disease was reported as endemic in the US, with numerous outbreaks in various states. Indirect contact would include common water and feed sources as well as shared equipment and common areas.

Efforts to establish freedom from infection based on thorough clinical, serological and virological monitoring of all animals are continuing in accordance with the HBLB Codes of Practice as advised by the Animal Health Trust and in consultation with the British Horseracing Authority. With those two horses testing negative for the virus, the quarantine was lifted on horses in the “general population” barns at Monmouth. It is most notable as a reason for spontaneous abortions in pregnant mares.
