A single 10-second smooch can transfer tens of millions of bacteria from one partner to the other. That’s the finding from a study in the journal Microbiome. [Remco Kort et al, Shaping the oral microbiota through intimate kissing]. More than 700 different bacteria are estimated to live in the human mouth. To find out how macking mixes microbes, Dutch scientists asked 21 couples to French kiss. 热吻分享的不仅仅是亲密的关系。短短10秒的接吻便能使成百上千万的细菌从一方的体内转移到另一方体内。这是发表在《微生物组学》杂志上发表的一篇研究得出的结论。人类的口腔中生存着超过700种不同的细菌。为了发现它们是如何混和在一起的，荷兰科学家对21对夫妻进行了法式热吻测试。 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. But kissing really expedites the bacterial blending. 男女朋友之间本来就已经由于共同生活的环境与习惯，他们彼此的嘴中含有的细菌组分在相似性上比他们与其他无关人员之间要高。但是接吻活动确实也能加速这些细菌之间的混合。 As part of the study, one member of the couple consumed a probiotic yogurt drink loaded with certain bacteria. Saliva samples and tongue swabs revealed that after the couples puckered up, about 80 million bacteria from the drink moved mouth to mouth. 该研究的一部分内容是，男女双方之一服用含有已知特定细菌的益生菌乳酸饮料。唾液样本和舌苔取样测试的结果都表明在这些男女彼此接吻过后，大约有8千万饮料中原有的细菌从一方的嘴中转移到另一方的嘴中。 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. Answering that question could help with future medical interventions aimed at microbes. 唾液中的细菌交换范围是广泛的，但是该研究仍没有告诉我们为什么某些交换了的细菌要么停留要么就瞬间消失。解答这个问题有助于将来开发针对微生物的医学干预措施。 What the research did show: although the bacteria in saliva were easily altered, bacteria living on tongues tended to stay put. Unlike certain frog-princes, those critters were less prone to change because of a mere kiss. 而这个研究确实展示给我们的是如下内容：尽管唾液中的细菌成分是很容易改变的，舌头上驻扎的细菌会保持原地不动。不像有些青蛙王子，那些奇葩生物可是不容易因为一个简单的吻就瞬间变身了。
