Avoid contact of new arrivals with individuals that have weakened immunity, young foals and elderly horses (>20 years of age) may be immunosuppressed. Whole blood samples were submitted from the population of horses in both of the previously quarantined barns today, and testing completed earlier this evening has identified a single positive EHV-1 horse (3yo TB colt) in one barn. Recovering horses may shed virus from nasal secretions for 2 weeks. The New Jersey Department of Agriculture’s Division of Animal Health has issued a quarantine at the Mid-Atlantic Veterinary Clinic in Ringoes, Hunterdon County, after a horse recovering from surgery there tested positive for the equine herpes virus. Develop a protocol and identify spokespersons. Improper care and disposal of the fetus may result in the spread of the disease to other horses.
Mares who abort usually require no specific treatment unless symptomatic or if injury has occurred during parturition. The quarantine has been lifted, but because the Forbes horses could not train during that period, they are not fit enough to run and may not be ready until later this month. Numerous cases of EHV-2 infection associated with signs of respiratory disease were reported in the US. Waterman recommends making sure your horse is vaccinated for the herpes virus. It is highly recommended that a veterinarian or authorized person perform a daily walk-through of the show barns to inspect exhibiting animals for any signs of illness. In South America, HPS is caused by the Andes virus in Argentina and Chile, the Bermejo virus in Bolivia and Argentina, the Oran and Lechiguanas viruses in Argentina, the Laguna Negra virus in Paraguay and Bolivia, the Choclo virus in Panama, and the Araraquara and Castelo dos Sonhos viruses in Brazil. Further outreach efforts included regional meetings for the state’s agriculture community with county extension agents, animal disease experts and division representatives.
The USDA plans to provide $158 million to the programs nationwide. 1 with the idea of keeping a tighter rein on what is administered to competition horses. Respiratory disease caused by EHV-4 was recorded by France (seven outbreaks), South Africa and Switzerland (single cases of infection), and the U.K. They are highly pathogenic for horses and also cause illness in humans. Outbreaks of EHV-4 respiratory disease were confirmed in France (11 outbreaks) and Germany (three outbreaks). Because infected horses may show no clinical signs, but still shed the virus, the temperature of suspect animals should be monitored twice daily for 14 -21 days and any abnormalities discussed with a veterinarian. All quarantines are based on risk assessment.
“There are two strains of EHV-1 ubiquitous in the environment. The neurologic form of EHV is a reportable disease in New Jersey. The EHV-1 virus spreads quickly from horse to horse, has a high morbidity and can cause a wide range of symptoms, from a complete lack of clinical signs to respiratory problems, especially in young horses, and spontaneous abortions in pregnant mares. When environmental conditions favor high viral amplification, significant numbers of “bridge vector” mosquitoes (mosquitoes that feed on both birds and mammals) become infected in the late summer and can spread the virus to humans, horses and other incidental hosts. King, Utah state veterinarian. Equine herpesvirus (EHV)-1 and -4 disease was recorded in France, Germany, Ireland, Japan, the United Kingdom, and the United States.

The most recent Census of Agriculture reported 233,770 poultry farms in the United States in 2012. “We consider this an emerging pathogen,” Pusterla said, noting that disease outbreaks associated with ECoV and adult horses have rarely been described in the scientific literature prior to recent years. Annual. New Jersey-based Trainer Tony Alagna, U.S. In addition, the Department is performing disease control and testing activities with the farm in order to limit the spread of the virus.
Initially, five outbreaks were recorded in French Saddlebreds and sports horses that had participated in several competitions. Dr. The horse acts a little depressed, then eventually starts to tremble and twitch. The causal agent, Taylorella equigenitalis, was detected in two stallions, one of whom had been used for breeding in Germany the previous year. Most of the 20 cases of equine infectious anemia diagnosed in horses in California during the third quarter of 2014 involved quarter horses illegally imported into the United States for non-sanctioned racing, the latest international update on equine diseases reveals. The Animal and Plant Health Inspection Service (APHIS) in cooperation with the National Animal Health Laboratory Network (NAHLN) oversees and implements the National Classical Swine Fever Surveillance Program.
