Management Procedures, Control, and Prevention

The event took place April 30 ? Vet. Eastern and Western Equine Encephalomyelitis Eastern equine encephalitis virus infects horses, pigs, birds, bats, reptiles, amphibians, forest-dwelling marsupials and rodents. Deaths have also been seen in squirrels in endemic areas, although West Nile virus has not been proven to be the cause. In people, Lyme disease is called the “great imitator”. This mighty be important in limiting the spread of the virus. Tasha Epp of The University of Saskatchewan’s College of Veterinary Medicine published risk factor data from their research.

After another 12 h, the horse was profoundly depressed and then developed a narcolepsy-like syndrome where it would collapse if touched. The average age of the horses was 3.2 y and 98 horses were ≤ 5 y old. Cells were stimulated with phorbol myristate acetate-ionomycin or infected at an MOI of 1. Nervous System. The “UMN bladder” was observed between 2 and 13 days after onset of ataxia (2, 4, 10, 12 and 13 days in grade 4 and 5 horses). The symptoms and severity of this disease vary considerably in different babies. Bar = 2 cm.

Equine Influenza – nothing to report. This can usually be done at the “Your Profile” page or by sending an email to EditorialAdvisor@mondaq.com. Three vaccinated Thoroughbreds were affected with clinical signs of coughing, nasal discharge and fever. On 25th September 2015, 30 cases were confirmed comprising 19 cases in 14 outbreaks in Bouches-du-Rhône, 10 cases in eight outbreaks in Gard and one case in Hérault. Am. The Eastern Equine Encephalomyelitis (EEE) virus is thought to have been the cause of EEE in North American horses since 1831. The Eastern Equine Encephalomyelitis (EEE) virus is thought to have been the cause of EEE in North American horses since 1831.

The vaccine is also contraindicated in foals less than 6 weeks of age, therefore maternal antibody protection of the foal through colostrum is the only way to protect them from contracting arteritis virus. Because of the low survival rate of infected foals, all broodmares should be vaccinated prior to breeding. France reported five outbreaks of rotavirus infection in foals. Common signs to look for are decreased appetite or activity level, coughing, fever and discharge from the nose or eyes. Foals born live should be considered a potent source of infection to naïve (previously unexposed), unvaccinated foals and horses in the herd. These stallions are no longer considered a reservoir of infection, and none have been shown to begin shedding equine arteritis virus at a later date. Horses suspected of having EHV infections should be examined by a veterinarian and tested for virus shedding.

Duncan said that he did not believe any horses other than those sent to Monmouth had been exposed to the virus. In one case, a private veterinarian visited a property in the southern agricultural region and examined two horses showing muscle fasciculations, head tremor and mild to moderate gait abnormalities. In an effort to enhance equine welfare, health and safety and overall horsemanship skills, the Grayson-Jockey Club Research Foundation will offer free, online horsemanship courses. Equine herpesvirus-1 and -4 (EHV-1, -4) related diseases were recorded in Argentina, France, Germany, Ireland, Britain, and the US. A Massachusetts native, she grew up in the saddle and has dabbled in a variety of disciplines including foxhunting, saddle seat, and mounted games. Horses with respiratory symptoms will typically lose interest in food as well. The 53rd running of the Riley Allison Derby, a prep race for the track’s signature event, the Sunland Derby, had been scheduled for Saturday but will not take place.

Thoroughbreds: Calvados, Yveline (in 2 different stables). During this period, the horse had a persistent low-grade fever and was treated with anti-inflammatory drugs and antibiotics. However, EHV-4 has never been known to cause neurological signs. The main points to remember about this disease are that the neurologic form (EHM) is deadly and the virus is highly communicable or contagious. The second affected horse was a 1.5-year-old Quarter Horse from Horry County, the EDCC reported. While most adult horses develop high immunity to re-infection after the illness runs its natural course, stallions often become silent carriers of EVA for years after exposure, thus becoming reservoirs of disease. With the one exception, the remaining donkeys were seronegative for antibodies to Burkholderia mallei.

No evidence exists of spread of CEM to the Thoroughbred population. The quarantine can be lifted at some point after that three-week period depending on the course of the disease. According to the Equine Disease Communication Center, that last reported case of EHV-1 was present in 14 horses at the Sunland Park Racetrack in New Mexico and as of Thursday, one horse had to be euthanized. The horse community is always just one step from a calamity and that calamity is a disease outbreak of such proportion as to widely imperil the health of our horses and threaten the economic viability of our industry.
