Colons of conventional and germ free mice

Caption

Images of the colons of conventional (left) and germ free (right) mice showing how bacterial colonization affects the distribution of immune cells along the mouse intestine. CD45 immune cells are show in red, CD3 immune cells are shown in yellow. Immune cells are concentrated close to the gut lumen, where bacterial colonization occurs. In germ free mice, this distribution is disturbed.
