〔編譯俞智敏／綜閤報導〕荷蘭一項最新研究顯示，隻要跟伴侶熱吻10秒鍾，你就可能和另一半分享高達8000萬個細菌，每天至少熱吻9次的愛侶們口腔裏的微生物群係也很相似。科學傢認為，親吻有助於讓伴侶們分享細菌，提升免疫係統作用，讓他們能夠對抗日後可能遭伴侶傳染的疾病。
法式熱吻 最快分享細菌範例
過去研究顯示，人類口腔裏有逾700種細菌。在荷蘭「應用科學研究院」（TNO）研究團隊的最新研究中，科學傢詢問21對伴侶有關其親吻習慣的問題，包括去年親吻的頻率，以及最後一次親吻的時間。接著科學傢分彆在這些誌願伴侶接吻10秒鍾前後採集舌頭與唾液中的細菌樣本，再讓伴侶中的一人喝下含有一群容易辨識細菌的益生菌飲料；當誌願者二度接吻時，科學傢就能偵測到傳遞給另一名伴侶的細菌數量，結果發現隻要熱吻10秒，即可傳遞平均多達8000萬個細菌。
主持這項研究的寇特（Remco Kort）教授錶示，法式熱吻正是在短時間內暴露於巨量細菌下的極佳範例，而且隻有人類纔有這種求偶行為。目前有關熱吻功用的解釋雖包括口腔內微生物群扮演的重要角色，卻還沒有人研究過熱吻對口腔內微生物産生的影響，因此這項研究的目的，就是要找齣伴侶們分享口腔內微生物的程度，結果發現愈常熱吻的伴侶，兩人口腔裏的微生物群係也愈相似。
研究人員發現，每天熱吻9次的伴侶，口腔裏的微生物群係非常相似，這錶示他們更有能力對付類似的感染，消化類似的食物。這項研究成果已刊登在「人體微生物群係」（Microbiome）期刊。
已有愈來愈多科學傢開始研究人體的微生物群係（microbiome），這是一種在人體體內和體錶生存、數量高達100兆的微生物生態係統。科學傢認為，這些細菌群係對於維持人體健康、預防疾病發揮關鍵作用。


看來以後要多多和伴侶熱吻瞭 哈哈!
但是其實原文內文都沒有提到可以提升免疫力喔
隻有提到口腔內的細菌會跟伴侶變得很像!!
所以這篇新聞講的提升免疫力是要幫它打個問號的!
但不失為一個熱吻的理由啦XDDD



附上原文摘要
Background
The variation of microbial communities associated with the human body can be the cause of many factors, including the human genetic makeup, diet, age, surroundings, and sexual behavior. In this study, we investigated the effects of intimate kissing on the oral microbiota of 21 couples by self-administered questionnaires about their past kissing behavior and by the evaluation of tongue and salivary microbiota samples in a controlled kissing experiment. In addition, we quantified the number of bacteria exchanged during intimate kissing by the use of marker bacteria introduced through the intake of a probiotic yoghurt drink by one of the partners prior to a second intimate kiss.

Results
Similarity indices of microbial communities show that average partners have a more similar oral microbiota composition compared to unrelated individuals, with by far most pronounced similarity for communities associated with the tongue surface. An intimate kiss did not lead to a significant additional increase of the average similarity of the oral microbiota between partners. However, clear correlations were observed between the similarity indices of the salivary microbiota of couples and self-reported kiss frequencies, and the reported time passed after the latest kiss. In control experiments for bacterial transfer, we identified the probiotic Lactobacillus and Bifidobacterium marker bacteria in most kiss receivers, corresponding to an average total bacterial transfer of 80 million bacteria per intimate kiss of 10 s.

Conclusions
This study indicates that a shared salivary microbiota requires a frequent and recent bacterial exchange and is therefore most pronounced in couples with relatively high intimate kiss frequencies. The microbiota on the dorsal surface of the tongue is more similar among partners than unrelated individuals, but its similarity does not clearly correlate to kissing behavior, suggesting an important role for specific selection mechanisms resulting from a shared lifestyle, environment, or genetic factors from the host. Furthermore, our findings imply that some of the collective bacteria among partners are only transiently present, while others have found a true niche on the tongue’s surface allowing long-term colonization.
