非洲豬瘟病毒最早在1921年肯亞的農場飼養豬隻被記錄，現時已傳遍亞洲、非洲、歐洲及大洋洲50多個國家。578Please respect copyright.ＰＥＮＡＮＡX8sihXyTsB

病毒主要攻擊的位置肝臟、腎臟等，豬隻的致命率可高達100%，而暫時沒有疫苗可預防病毒引發的症狀。578Please respect copyright.ＰＥＮＡＮＡLyrfOR04vW

(圖2)家豬未被引入之前，非洲豬瘟病毒在大自然間主要經由蜱及非洲疣豬兩者互相傳播。578Please respect copyright.ＰＥＮＡＮＡMZASI5AqGL

作為非洲豬瘟病毒天然宿主的非洲疣豬，就算被感染上高劇量的非洲豬瘟病毒，亦不會出現任何症狀。578Please respect copyright.ＰＥＮＡＮＡjlrAfnpiV5

那麼，為何家豬受感染後又會出現症狀呢?578Please respect copyright.ＰＥＮＡＮＡvfokxj9vw0

(圖3)尋覓原因之際，有報告指出無菌環境長大的豬隻，較容易受到出現非洲豬瘟病毒引起的症狀(Ref1)。578Please respect copyright.ＰＥＮＡＮＡsvALiO4yD4

而無菌環境長大及農場環境長大其中一種最大的分別，就是無菌環境長大的豬隻腸道上不含細菌。578Please respect copyright.ＰＥＮＡＮＡKkYXUanCDk

(圖4)腸道細菌能夠協助宿主的免疫反應產生，基於這一點，科學嘗試將對於非洲疣豬的腸道細菌移植到家豬腸道裡頭(Ref2)。578Please respect copyright.ＰＥＮＡＮＡFoY8M5YFoQ

非洲疣豬的排泄物內含其所屬的腸道細菌，經處理過後，排泄物由食道經過導管送到豬隻腸道裡。578Please respect copyright.ＰＥＮＡＮＡ7Cf3O1wwY9
578Please respect copyright.ＰＥＮＡＮＡZ6w5SVc8sN
研究發現，被移植腸道細菌的家豬與沒有進行移植的家豬相比，被受非洲豬瘟病毒感染後，症狀出現率大致相同。578Please respect copyright.ＰＥＮＡＮＡHSCgqn7hau
578Please respect copyright.ＰＥＮＡＮＡK3vPW423a7
但若果換成為弱化感染力的病毒，被移植腸道細菌的家豬出現的症狀明顯有所減輕。578Please respect copyright.ＰＥＮＡＮＡntj9geHsLZ

只不過，文中作者強調利用糞便移植的手段並沒能將所有品種透徹地進行轉移。578Please respect copyright.ＰＥＮＡＮＡwBKlU9GQ9C
如果能夠準確找出非洲疣豬腸道哪一種細菌品種對抵抗病毒有顯著功效，然後再作針對性的腸道細菌移植，或者亦有機會可以幫忙家豬對抗非洲豬瘟病毒。578Please respect copyright.ＰＥＮＡＮＡDlad4rNl2t
