Microbiota at the family level whose occupancy was significantly different in ASD subjects are presented with associated higher taxonomy levels. Those occupying 0.1% or higher in either normal healthy or ASD subjects were included. ↑ and ↓ denote an increase and decrease in the percent composition, respectively. Data are the mean percentages. * and ** denote significant differences between the indicated groups at p<0.05 and p<0.01, respectively (Student's t-test).
