hands harbored, on average, 158(in the range 46-401) unique species-level bacterial phylotypes, and among the 51 healthy volunteers, they identified a total of 4,742 unique phylotypes across the 102 hands examined. The bacterial diversity was more expressed in females than in males. The bacterial skin flora varies qualitatively and quantitatively by body site, gender, age, health condition, hospitalization, season,handedness, and the time interval between last hand washing and skin sampling.
在对51名健康志愿者检查中,他们发现每人的双手中隐藏平均约158种(范围在46-401)独特的种系型细菌,整个检查的102只手中共有4742个独特的种系型细菌。细菌多样性更表现在女性高于男性。皮肤菌群中细菌的定性、定量变化与身体部位、性别、年龄、健康状况、住院期间、季节、利手倾向(右利手或左利手),及最后洗手和皮肤采样之间的时间间隔有关。
