Abstract

SUMMARY(1) Nine dogs fed on diets restricted to fat meat (pork), overcooked turnip greens, corn meal, and sorghum all developed positive van den Bergh reactions after the artificial induction of pneumonia. These animals all had marked fatty degenerative change in the liver on pathological examination.(2) Eleven dogs fed on similar diets plus brewer's yeast failed to develop positive van den Bergh reactions after artificial induction of pneumonia. The lung changes in this group were far less severe than in the control group and only one animal in this series exhibited marked fatty degenerative changes in the liver on pathological examination.(3) The authors have previously noted an unexplained high incidence of jaundice in Negro patients with pneumonia whose diets were known to be similar to the restricted diets used in this study.
