Clinical report of a paralytic syndrome affecting stallions, mares and foals on a thoroughbred studfarm.

This research article discusses a paralytic syndrome outbreak on a Thoroughbred studfarm, caused by equid herpesvirus (EHV1), affecting stallions, mares, and foals.

Background of the Research

• The study was sparked by an outbreak of ataxia and paralysis on a Thoroughbred studfarm, a rare occurrence which impacted the well-being of the horses, showing a significant event within the animal healthcare field.
• The cause of the disease was found to be equid herpesvirus (EHV1), originating from a single 10-month abortion on the farm.

Effects of the Outbreak

• The breeding horses of all types; stallions, mares and foals, were infected. But, the mares showed the most serious clinical symptoms, indicating a potential element of gender or age vulnerability.
• The report provides specific statistics, reporting that out of 39 mares, 35 exhibited signs of ataxia. Meanwhile, only 2 out of 4 stallions and 5 out of 39 foals showed similar symptoms. Therefore, the disease seems to be more prevalent or severe in mares.
• The disease led to severe consequences, with nine of the affected mares becoming so impaired that they either died naturally or had to be euthanased.

Treatment and Spread Control

• The treatment plan for the infected horses involved administering betamethasone and antibiotics. Nevertheless, the efficacy of these treatments is not mentioned in detail within the abstract.
• The research article states that the outbreak was primarily contained within one area of the studfarm. There was, however, secondary spread to two mares who had contact with the affected horses and were based on different premises, indicating that the virus was contagious but could be contained with proper care and quarantine protocols.
