Equine piroplasmosis visits Australia in 2000.

The research article discusses an incident of tick-borne protozoal disease called Equine piroplasmosis that affected a thoroughbred gelding horse imported to Australia from Hong Kong. The horse, despite being detected positive for the disease, was allowed to travel due to an oversight, bringing to light the potential risks of disease transfer in the import processes.

Background of the Study

• The research revolves around the import of a horse from Hong Kong to Australia that was positive for equine piroplasmosis, a ticks borne disease that affects horses causing fever, anaemia, and jaundice. The Australian Quarantine and Inspection Service (AQIS) detected the error after the horse’s arrival in the country.

Main Findings

• On retesting all the seven horses (including the infected one) post-arrival, it was confirmed that only the imported gelding horse was positive for the disease.
• To prevent the transmission of the disease, the infected horse was euthanized, and its body incinerated.
• As a precautionary measure, the other six horses were kept in isolation for 36 days under new quarantine rules. These horses were allowed to be released from quarantine control only after they tested negative for the disease.

Humphrey’s Response

• In response to the incident, Hong Kong swiftly initiated extensive testing of every horse in the territory (1562 horses), and all equine properties were inspected for ticks.
• The Hong Kong Jockey Club’s Veterinary Department ensures the use of new needles and syringes for every treatment, decreasing the chances of disease spread.
• The conditions for the import of horses from piroplasmosis-affected countries to Hong Kong have been changed to mandate a negative IFAT (Indirect Immunofluoresence Antibody Test) for equine piroplasmosis, and all horses have to be treated with an approved insecticide before export.

Significance of the Study

• The study draws attention to the necessity of strict import regulations and adequate testing mechanisms to avoid the accidental transfer of diseases across borders.
• It also underscores the importance of stringent quarantine measures and prompt response in containing the spread of such diseases.
