FIG 2.

Identification of fecal bacteria of ovalbumin (OVA)-specific food-allergic mice. Feces from food-allergic (OVA/alum) and control (phosphate-buffered saline [PBS]/alum) mice were collected and analyzed using a Vitek MALDI-TOF MS system. The numbers of identified fecal bacteria derived from each group of mice (OVA/alum group, OVA/alum 1 to OVA/alum 5; PBS/alum group, PBS/alum 1 to PBS/alum 5) are indicated in the left bar graph. Results are presented as the mean ± standard error (SE) (n = 5). *, P < 0.05. The presence of Citrobacter sp. in all fecal samples from both groups of mice is indicated in the circle charts on the right.
