Relative abundance of bacterial families that were significantly different in the house dust samples of allergic subjects as compared to non-allergic subjects. Relative abundance of bacterial families in house dust samples from the bed (a), play area (b), and sofa (c) of allergic and non-allergic subjects were transformed into Z-score and represented using heat maps. Raw relative abundance of Anaplasmataceae (d), Bacteroidaceae (e), and Leptospiraceae (f) in the house dust samples from the bed (○), play area (□), and sofa (∆) of allergic (open) and non-allergic (close) subjects were represented using dot plot. Red line represents the mean of each group. Red line represents the mean of each group. Asterisk (*) represents significant difference of IndVal value > 0.6 and P-value < 0.05
