科普專欄–薯不揀單 - 三十秒科學–母乳餵哺對嬰兒的其中一道影響

早前曾講述自然產子及剖腹產子對嬰兒的腸道細菌品種有何影響，而今篇文章將會講解母乳餵哺對其的影響力。475Please respect copyright.ＰＥＮＡＮＡ4ASyk0Z6Nj

(圖2)科學家找來20名嬰兒，分別採樣0個月(即出生後11-152小時)、1個月及4個月的嬰兒糞便，並發現病毒基因並不會在0個月期間的嬰兒糞便尋覓得到，而在1個月及4個月的糞便中則找到病毒基因的存在。475Please respect copyright.ＰＥＮＡＮＡ2Ryu98rnhk

這些病毒的出現，相信是從腸道而起。475Please respect copyright.ＰＥＮＡＮＡWP5hGLKmil

(圖3)經一系列的研究顯示，細菌及病毒寄宿在嬰兒腸道的過程至少被分成為兩種階段。475Please respect copyright.ＰＥＮＡＮＡ6rhZFNgRY4

第一階段中，含有病毒基因的細菌率先駐紮在嬰兒腸道內，病毒會因應時機從細菌中開始繁殖、或一直呈基因狀態與細菌共存。475Please respect copyright.ＰＥＮＡＮＡUMM12Y4IgJ

至於第二階段，則為外來的病毒以自身的方式入侵腸道。475Please respect copyright.ＰＥＮＡＮＡiplS9S1Fwe

而這裡亦是母乳餵哺方式囑目的地方，因為以母乳餵哺或母乳及奶粉混哺的嬰兒，其糞便的病毒數量顯著地比只用奶粉餵哺的為低。475Please respect copyright.ＰＥＮＡＮＡ2JLYwaeklB

這顯著的分別，相信是母乳所含的抗體及相關蛋白質及糖份有著抑壓病毒的能力所致。475Please respect copyright.ＰＥＮＡＮＡHgg3UQQrwe
