科普專欄–薯不揀單 - 深入淺出–關於非洲豬瘟病毒的一項研究

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。565Please respect copyright.ＰＥＮＡＮＡOY1WGb2bmj

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。565Please respect copyright.ＰＥＮＡＮＡ7v8HKdT8IH

(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。565Please respect copyright.ＰＥＮＡＮＡ865QZ70066

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。565Please respect copyright.ＰＥＮＡＮＡ30koQdsyw4
565Please respect copyright.ＰＥＮＡＮＡjwlZzI2s3s
那麼，為何家豬受感染後又會出現症狀呢?565Please respect copyright.ＰＥＮＡＮＡjnfoysb67x

(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)。565Please respect copyright.ＰＥＮＡＮＡH0D8M10RuA

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。565Please respect copyright.ＰＥＮＡＮＡhYycJoDXDI
565Please respect copyright.ＰＥＮＡＮＡAS81OOkkTM
(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)。565Please respect copyright.ＰＥＮＡＮＡnqNrfpJyoY

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。565Please respect copyright.ＰＥＮＡＮＡFG5PPCorwV
565Please respect copyright.ＰＥＮＡＮＡOaNyj4YFHY
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。565Please respect copyright.ＰＥＮＡＮＡhh8A7yyOjV
565Please respect copyright.ＰＥＮＡＮＡEmCMSAwdc3
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。565Please respect copyright.ＰＥＮＡＮＡsH6fhKXu74

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。565Please respect copyright.ＰＥＮＡＮＡfgpptHNust
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。565Please respect copyright.ＰＥＮＡＮＡi5w64uTLQU
