Microbiome:伴侣接吻10秒就可转移8000万个细菌

2014-11-18 佚名 生物谷

近日,一篇发表在国际杂志Microbiome上的研究论文中,来自荷兰应用科学研究院等处的研究人员通过研究发现,在接吻的10秒时间内接吻双方在两者口腔中可以转移将近8000万个细菌,而伴侣间一天接吻至少9次,因此伴侣间或许会共享相同的口腔微生物群体。在我们的机体中生存着超过100万亿个微生物,这些微生物组成的微小生态系统就称之为微生物组,其对于我们机体消化食物、合成营养物质及抵御疾病发生非常必要。而

近日,一篇发表在国际杂志Microbiome上的研究论文中,来自荷兰应用科学研究院等处的研究人员通过研究发现,在接吻的10秒时间内接吻双方在两者口腔中可以转移将近8000万个细菌,而伴侣间一天接吻至少9次,因此伴侣间或许会共享相同的口腔微生物群体。

在我们的机体中生存着超过100万亿个微生物,这些微生物组成的微小生态系统就称之为微生物组,其对于我们机体消化食物、合成营养物质及抵御疾病发生非常必要。而机体的微生物组常常也会被遗传机制、饮食和年龄等所影响,在个体口腔中大约有700多种形形色色的细菌,口腔中的微生物往往会因与我们亲近的人所影响(伴侣间)。

文章中,研究人员Remco Kort对21对夫妇进行研究,让其填写关于接吻行为的调查问卷,其中包括他们平均直接接吻的频率,随后对参与者的口腔拭子样本进行研究,分析个体舌头的唾液中的口腔微生物组成成分。结果显示,当伴侣间亲吻达到一种相对较高的频率时,其唾液中的微生物就会变得非常相似,而每天至少9次接吻就会使得伴侣间口腔共享相同的唾液微生物。

亲密接吻包括完全的舌头接触(舌吻)以及唾液交换,这似乎是人类特有的求偶行为,有意思的是,当前人类亲密接吻对于口腔微生物的具体影响尚未研究过,因此这项研究中,研究人员就想知道哪些伴侣可以共享口腔微生物,结果显示,伴侣间亲密接吻次数越多,其口腔中微生物的相似度就越高。

在一项亲吻控制实验中为了定量伴侣间口腔所转移的细菌含量,研究人员让伴侣中的一人饮用含有包括乳杆菌和双歧杆菌的特殊种类细菌的益生菌饮料,随后伴侣间亲密接吻,研究人员开始对另一位伴侣进行研究,结果发现未饮用益生菌饮料的个体口腔中的益生菌含量升高了三倍,据估计大约在10秒的接吻时间内伴侣间的口腔可以转移大约8000万个细菌。最后研究者表示,74%的男性相比其伴侣女性有更高的亲密接吻频率,有报道表明,男性平均每天的亲吻10次,而女性仅为5次。
