Abstract: | ![]() A comparison between germfree (GF) and gnotobiotic (GB) mice, inoculated with Bacteroides vulgatus, Eubacterium aerofaciens, Bifidobacterium longum, Enterococcus faecalis, Escherichia coli, and Clostridium perfringens, revealed that the GB mice suffered no deleterious effect on the apparent absorption ratios of Ca and P, and showed a higher apparent absorption ratio of Mg. |
