Fig. 1From: Temporary establishment of bacteria from indoor plant leaves and soil on human skinLog10 bacterial 16S gene copy abundances for skin, outdoor soil, and leaf samples prior to the transfer event. Note that samples were not normalized by dry weight or surface area; skin samples represent a 3 cm2 surface area, soil samples represent 0.0075 g of soil, and leaf samples represent a 100 cm2 surface areaBack to article page
