Abstract

The current study is the first paper on FPT(failure of passive transfer) of horse population in Korea. The object of this study was to comparison of immune status normal and patient horses. Failure of passive transfer is the most common immunodeficiency disorder of horses. Twenty-two foals and 18 horses from Jeju of the equine hospital were diagnosed with the SNAP Foal IgG Test Kit. All adult horses had normal immune functions (≥800 mg/dl). Thirteen of the 22 newborn babies (59%; ∠800 mg/dl) had a weak immune function but recovered and survived after treatment. Nine of these 22 are horses with strong immunity (≥800 mg/dl), indicating that high IgG concentrations in the blood can cause infectious diseases. There were a total of six dead, four of which were infectious diseases. In addition, early identification of infectious diseases in newborn foals is expected to help prepare systematic health management measures for the development of the disease.

이 연구는 최초의 국내 말에서 수동면역부전을 다룬 것이다. 이 연구의 목적은 건강한 말과 아픈 말의 면역상태를 비교하는 것이다. 수동면역부전은 말에서 가장 흔한 면역결핍질환이다. 아픈말 22 마리와 건강한 말 18 마리를 검사키트(SNAP Foal IgG Test Kit)를 이용하여 수동면역부전을 진단하였다. 모든 성마는 정상적인 면역기능을 가지고 있었다(≥800 mg/㎗). 신생망아지는 22 마리 중 13 마리(59%; ∠800 mg/㎗)가 면역기능이 취약하였지만 치료 후 회복하여 생존하였다. 이 22 마리 중 9 마리는 면역기능이 강한 말(≥ 800 mg/㎗)로 혈중 IgG농도가 높아도 감염성 질환이 발생할 수 있다는 것을 보여준다. 폐사망아지는 모두 6 마리였고, 그중 4 마리는 감염성 질환이었다. 신생망아지 면역상태 검사를 통한 감염취약 정도의 조기진단 및 대응방안 마련으로 경주자원 활용율 제고와 보건관리 기술향상을 도모할 수 있다. 또한, 신생망아지의 감염성질환 조기 파악으로 향후 육성마의 체계적인 보건관리방안 마련에 일조할 수 있을 것으로 기대된다.
