Fig. 2

Bacterial diversity among dust samples from the bed (○), play area (□), and sofa (∆) of allergic (open) and non-allergic (close) subjects. Bacterial diversities were represented by Shannon Index (a) and Simpsons Index (b). Red line represents the median of each group. There were no difference in bacterial diversity between bed dust samples of allergic subjects and non-allergic subjects using Mann-Whitney U test. Similar trend was observed for play area and sofa samples
