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 Candida albicans, 5% with C. guilliermondi, 3% with C. lusitaniae and 3% with C. parapsilosis.

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 C. albicans 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.

在这项研究中，使用基于培养的方法对 181 名健康个体（包括 29 对夫妇）的口腔酵母菌定植进行了分析。结果显示，39%的个体是酵母携带者，其中89%定植有白色念珠菌，5%定植有吉列蒙念珠菌，3%定植有卢西塔尼亚念珠菌，3%定植有近平滑念珠菌。

百分之六十二的夫妇至少有一名成员被殖民。夫妇组中的定植率和 CFU 计数较高。80% 的志愿者被仅具有一种 CAI 基因型的白色念珠菌菌株定植，而其余 20% 个体的口腔中栖息着两种但相似的 CAI 基因型。当双方都被定植时，66.6% 的夫妇发现了相同的 CAI 基因型。

我们的研究结果表明，夫妻之间的亲密关系增加了严重交叉殖民的可能性，当夫妻中的一个成员是吸烟者时，这种情况会加剧。
