上集講述了腸道細菌的品種變異有助大腸癌形成的證據。887Please respect copyright.ＰＥＮＡＮＡiJQil6d71S

而除大腸癌外，腸道細菌的品種對成長方面亦會構成影響。887Please respect copyright.ＰＥＮＡＮＡ82PHEMJy78

(圖2)世衛(WHO)用上來自6個國家的8440個健康兒童三項數據887Please respect copyright.ＰＥＮＡＮＡbNpeFGfa3q
(重量對比高度、重量對比歲數及高度對比歲數)，定立了兒童是否呈營養充足的標準。887Please respect copyright.ＰＥＮＡＮＡVzgYM4P9Az
887Please respect copyright.ＰＥＮＡＮＡFApT1glkTf
887Please respect copyright.ＰＥＮＡＮＡUvqO1liGWP
若兒童的三項數據低於某一個程度，兒童便會界定為營養不良的狀態。887Please respect copyright.ＰＥＮＡＮＡivnWf1KTAx

(圖3)根據世衛定下的標準界定其營養攝取量是否充足，有科學家收集來自非洲東南部的內陸國家馬拉威6-18月大的兒童糞便，透過糞便移植(從口中灌入)將人類腸道的細菌寄居到老鼠的腸道中，從而探討腸道細菌對生長的影響（Ref1)。887Please respect copyright.ＰＥＮＡＮＡFg9qP27uhD

(圖4)在食物款式一模一樣的情況下，移植營養充足兒童糞便的老鼠，其整體重量及肌肉重量均比移植營養不良兒童糞便的老鼠為高。887Please respect copyright.ＰＥＮＡＮＡ9h5mjUIKMf

重要的是，兩組老鼠的進食量及體脂均無顯著分別。887Please respect copyright.ＰＥＮＡＮＡ3z0BkDEach
887Please respect copyright.ＰＥＮＡＮＡLuNEvGQH4A
亦即是表示在食物攝取量一樣的狀態下，移植營養充足兒童糞便的老鼠，其肌肉的增長相對上較高。887Please respect copyright.ＰＥＮＡＮＡ8nTTr4Xby4
887Please respect copyright.ＰＥＮＡＮＡwM9WPBU4tm
(圖5)科學家繼而作出另一實驗，糞便移植4日後，老鼠便開始進行不同組別的定居。887Please respect copyright.ＰＥＮＡＮＡSRGAPWOb4A
887Please respect copyright.ＰＥＮＡＮＡn1uWIPqPqd
887Please respect copyright.ＰＥＮＡＮＡb8RDQbJhJR
當移植營養充足兒童糞便的老鼠與營養不良兒童糞便的老鼠一同定居後，兩者的肌肉重量再也沒有分別。887Please respect copyright.ＰＥＮＡＮＡxDqxbwgup6
887Please respect copyright.ＰＥＮＡＮＡ65jBYDvqU8
但兩組分別飼養的話，移植營養充足兒童糞便的老鼠的肌肉重量顯然比營養不良兒童糞便組別為重。887Please respect copyright.ＰＥＮＡＮＡNLbvkBjyvH
887Please respect copyright.ＰＥＮＡＮＡhSsSJn5fph
(圖6)科學家發現，不同組別的老鼠定居後，老鼠的腸道群組亦同化成為營養充足的腸道群組。887Please respect copyright.ＰＥＮＡＮＡhCS02SKiDg

887Please respect copyright.ＰＥＮＡＮＡAzjELATdPD
而經過一系列的實驗後，科學家提出R. gnavus 及 C. symbiosum這兩細菌品種在改變新陳代謝方面上具有重大的影響力，引致老鼠生長不良的情況。887Please respect copyright.ＰＥＮＡＮＡU5l2x5oybM
