A passionate kiss shares much more than intimacy.
一個深情之吻傳遞的可不只是濃情蜜意。
A single 10-second smooch can transfer tens of millions of bacteria from one partner to the other.
僅僅一個10秒的吻就會將一方數以千萬的細菌傳給另一方。
That's the finding from a study in the journal Microbiome.
這一研究已經在《微生物》雜志上發表。
More than 700 different bacteria are estimated to live in the human mouth.
據估計人類口腔中有700多種截然不同的細菌。
To find out how macking mixes microbes, Dutch scientists asked 21 couples to French kiss.
為了搞清楚接吻如何將細菌混合，荷蘭科學家們要求21對情侶進行法式接吻。
Intimate partners already have more of the same bacteria in their mouths than do unrelated individuals, because of the couple's shared habits and environment.
同毫不相干的人相比，擁有共同生活習慣及環境親密情侶的口腔內已經有很多相同的細菌。
But kissing really expedites the bacterial blending.
但接吻確實會加速細菌混合。
As part of the study, one member of the couple consumed a probiotic yogurt drink loaded with certain bacteria.
而其中一項研究要求情侶中的一人進食具有特定細菌的益生菌酸奶飲品。
Saliva samples and tongue swabs revealed that after the couples puckered up, about 80 million bacteria from the drink moved mouth to mouth.
而后的唾液樣本及舌頭化驗顯示，在情侶接吻后這種飲品中的8千萬個細菌通過嘴進行了傳遞。
The salivary bug exchange was extensive but the work does not yet tell us why certain swapped bacteria either stuck around or were more transient.
唾液細菌傳播量非常大，但這項研究尚未揭開為何某些交換后的細菌要么滯留要么轉瞬即逝的謎團。
Answering that question could help with future medical interventions aimed at microbes.
如若能找到這個問題的答案，或許對未來針對微生物的醫療干預會有所幫助。
What the research did show: although the bacteria in saliva were easily altered, bacteria living on tongues tended to stay put.
此項研究表明盡管唾液中的細菌很容易改變，但舌頭上的細菌卻很穩定。
Unlike certain frog-princes, those critters were less prone to change because of a mere kiss.
這些小生物可不像青蛙王子，不會因為一個吻就發生改變。
