摘要

馬傳染性貧血（EIA）是反轉錄病毒科（Retroviridae）之病毒所引起的。受感染的馬匹會終身帶原，典型症狀會出現高熱、貧血。母馬會造成流產，病毒也能傳染胎兒。大多數感染馬匹可能呈現無症狀或症狀不明顯的帶原狀態。自2001年張詠樂等人進行的調查後，10年來台灣未曾再進行調查。本研究對台灣地區進行調查。採集217個血清樣本，分別為臺灣北部（台北、桃園、新竹）121匹、中部（苗栗、台中）41匹、南部（高雄、屏東）35匹和東部（花蓮、台東）20匹，採集馬場共23場。以酵素免疫分析法（Enzyme-linked immunosorbent assay, ELISA）檢測樣本之抗體，皆為陰性反應。自1992年楊揚輝等人的調查報告全台有2.1%的陽性率後，20年間已數次調查無陽性結果。可視為馬傳染性貧血防治上的成功，但未來還是需要後續的調查以保持成果。

A lentivirus belonging to the Retroviridae family is responsible for equine infectious anemia (EIA), and infected horses are carriers for life. Equine infectious anemia is clinically characterized by fever, anemia, can lead to abortion, and the virus can infect fetuses. Most infected horses are latent carriers and show no obvious clinical signs, or show mild signs in the chronic stage. Equine infectious anemia in Taiwan has not been investigated in the past decade. Here, we used 217 blood samples from the northern (Taipei and Taoyuan, Hsinchu), central (Miaoli, and Taichung), southern (Kaohsiung and Pingtung), and eastern (Hualien and Taitung) regions of Taiwan. Samples were tested by enzyme-linked immunosorbent assay, and no positive results was obtained. In 20 years, we have no positive sample been tested. It can be seen as a success of EIA elimination strategies, but still need to continuously investigate in the future.
