P. copri colonization did not affect the phenotype of DSS colitis. a Body weight change in vehicle-treated (n = 5) and P. copri-inoculated mice (n = 6) receiving 2.5% DSS in drinking water. The data are presented as the mean ± SD. b Relative mRNA expression levels of TNFα in the colon of the DSS-induced mice. c Representative images of HE-stained colon samples from the DSS-induced mice. Arrows indicate mucosal tissue destruction and loss of goblet cells; arrowheads show lymphocyte accumulation in lamina propria.
