Suppression of the microbiota does not influence TcdA/B‐induced innate immune cell infiltration into the colon. The influx of innate immune cells into the colonic lamina propria was assessed 4 h after TcdA/B exposure in mice given normal water or mice given antibiotic (ABX)‐supplemented water. Representative flow cytometry plots and associated cell counts of infiltrating Ly6C^hi monocytes (CD11b⁺Ly6C⁺), neutrophils (CD11b⁺Ly6G⁺), and eosinophils (CD11b⁺Siglec‐F⁺) in the colonic lamina propria of control and ABX‐treated mice following TcdA/B exposure (n = 4‐5 mice per group). All data are expressed as SEM. Student's t test
