Effects of dietary composition on growth of M. leprae in mouse footpads.
The number of bacteria per mouse footpad were measured at intervals beginning with the third month in male, weanling BALB/c mice infected with M. leprae and fed for a period of 6 months to test the effects of diet on multiplication of bacteria. The mean bacteria count per footpad in mice remaining at 6 months in the two high fat diets was higher (p = 0.014) than the mean of the two low fat diets. Likewise, the pooled mean bacterial count of mice fed the two diets of animal origin had a tendency to a higher mean bacterial count compared to mice fed the two diets of plant origin. Low level of dietary protein in early life also seemed to predispose to M. leprae multiplication. Our data in mice suggest that the association of diet with human leprosy should be investigated.
