Increased Resistance to Ulcerative Cecitis of Rats on a Diet Deficient in the Vitamin B Complex

Abstract

Rats which received a diet deficient in the vitamin B complex over a period of months failed to develop “spontaneous ulcerative cecitis” except, very mildly, in an occasional animal. One-half of the litter-mate controls, on the other hand, had the disease, for the most part in well-advanced form. This, then, is an example of increased resistance to infection, rather than increased susceptibility, brought about by undernutrition and vitamin deficiency.
