Table 3 Average relative abundance of the top 15 bacterial genera in high schools in Shanxi and their relative abundance in other habitats. The bacterial abundance in air, non-saline soil and freshwater, and the human gut, saliva and skin environment were calculated from the Earth Microbiome Project [41]. The bacterial abundance in the university dormitory and junior high school was calculated from two recent publications [12, 42]. Taxa with relative abundance > 0.1% were formatted with bold font
