Male, weanling, axenic mice were maintained under three conditions of intestinal flora on six diets. The results showed that mice with a conventional normal intestinal microflora required more lysine and methionine than their counterparts which were either germfree or inoculated with a limited flora. The effect was noticeable only when lysine and methionine levels were nearly at a minimum for growth of the mice.
