Figure 2. The pediatric gut microbiomes of children with IBS are characterized by greater abundance of Gammaproteobacteria.
A) Percentage of all bacterial classes represented. B) Percentage of bacterial taxa found in lower abundance (< 5% of total bacteria). Healthy children: 29 samples from 22 subjects, IBS: 42 samples from 22 patients. #: Significantly different between IBS and healthy children (P <.05). Data were generated by 454 pyrosequencing (V1–V3 region).
