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。625Please respect copyright.ＰＥＮＡＮＡtsTt5wxmVY

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。625Please respect copyright.ＰＥＮＡＮＡ9waekb6exi

(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。625Please respect copyright.ＰＥＮＡＮＡH1xN7SD6Qz

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。625Please respect copyright.ＰＥＮＡＮＡqf0DMXyvIf
625Please respect copyright.ＰＥＮＡＮＡcYx9GmX3dA
那麼，為何家豬受感染後又會出現症狀呢?625Please respect copyright.ＰＥＮＡＮＡrrgk3QZ6Qn

(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)。625Please respect copyright.ＰＥＮＡＮＡQC1KFyFRcJ

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。625Please respect copyright.ＰＥＮＡＮＡaUgLh6mnvy

(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)。625Please respect copyright.ＰＥＮＡＮＡGBGIpNm56C

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。625Please respect copyright.ＰＥＮＡＮＡ378j52FNYZ
625Please respect copyright.ＰＥＮＡＮＡ3SyX3Om5Rz
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。625Please respect copyright.ＰＥＮＡＮＡqSSmhYeZPb
625Please respect copyright.ＰＥＮＡＮＡ734uwylVqv
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。625Please respect copyright.ＰＥＮＡＮＡ9XyCKa0OwE

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。625Please respect copyright.ＰＥＮＡＮＡyaZvKcqm7u
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。625Please respect copyright.ＰＥＮＡＮＡYtqYA8d5zS
