FIG. 6.

Production of anti-M. morganii specific IgA in supernatant of organ fragment cultures of PP and small intestine (SI) of GF mice, conventionally reared C3H/HeN mice, and C3H/HeN mice that had been monoassociated with SFB and then double associated (at day 113) with M. morganii. RIA was used to detect IgA. Data are means ± standard errors of the mean. Four fragment cultures were done per tissue per time point.
