In this study, 181 healthy individuals, including 29 couples, were analysed regarding oral yeast colonization using a culture-based approach. Results showed that 39% of the individuals were yeast carriers, 89% being colonized with , 5% with , 3% with and 3% with . Sixty-two percent of the couples had at least one member colonized. Colonization and CFU counts were higher in the couples´ group. Eighty percent of the volunteers were colonized with strains with only one CAI genotype, while two but similar CAI genotypes inhabited the oral cavity of the remaining 20% individuals. The same CAI genotypes were found in 66.6% of the couples when both were colonized. Our results indicate that the intimacy among couples increases the probability of heavy cross-colonization, which is potentiated when one member of the couple is a smoker.
在本研究中，采用基于培养的方法对181名健康个体（包括29对夫妇）进行了口腔酵母菌定植分析。结果显示，39%的个体为酵母菌携带者，89%的个体定植有 ，5%的个体定植有 ，3%的个体定植有 ，3%的个体定植有 。62%的夫妇中至少有一名成员被定植。夫妇组的定植率和菌落形成单位计数更高。80%的志愿者定植有仅一种CAI基因型的 菌株，而其余20%个体的口腔中存在两种但相似的CAI基因型。当夫妇双方都被定植时，66.6%的夫妇中发现了相同的CAI基因型。我们的结果表明，夫妻间的亲密关系增加了严重交叉定植的可能性，当夫妻中的一方为吸烟者时这种可能性会增强。
