Couples who live together agree to share a lot of things, like a bed, a bathroom, and a kitchen. Naturally, when you move in with a partner, everything changes, including your skin bacteria. Researchers at the University of Waterloo in Ontario, Canada have found when we live with a significant other, we exchange bacteria, which causes our microbial profile to change. 同居的情侣会共用很多东西，比如：床、浴室和厨房。因此，当你搬去和另一半同住时，一切都自然而然的发生了变化，包括肌肤上的细菌。加拿大安大略省滑铁卢大学的研究人员发现：当我们与另一半住在一起时，我们会交换细菌，导致自身的微生物分布状态发生改变。 In the study, published in MSystems, an open-access journal of the American Society for Microbiology, researchers found each person in the relationship significantly influenced the microbial communities on their partner's skin. Using microbial data, computer algorithms were able to match couples with 86 percent accuracy. The body part most likely to host skin bacteria shared by a couple were the feet. 该研究发表在美国微生物学会的MSystems期刊上，大众可自行获取。研究员发现：恋爱关系中的每一个人都会影响另一半皮肤上的微生物群。使用微生物数据和计算机算法可匹配情侣，精确度高达86%。情侣之间最容易宿主皮肤细菌的身体部位就是双脚。 |
