Figure 6.
Coordinated colonic contractions are regulated by Bt.
Raw traces showing manometric pressure recordings in the whole colon in SPF (a), GF (b) and Bt-CONV (c). The number of colonic migrating motor complexes (CMMCs)/min is significantly increased in GF conditions compared to SPF and further upregulated in Bt-CONV compared to GF conditions (d). The frequency of contractions (peaks/min) is only increased in Bt-CONV compared to SPF and GF only in the proximal colon. The amplitude of contractions across all colonic regions and mouse groups is unchanged. N = 5. Error bars show SEM, and significance is p < .05 as denoted by *.
