EXPERIMENTAL STUDY ON THE CHANGES IN THE INTESTINAL FLORA IN RABBITS WITH MULTIPLE SYSTEM ORGAN FAILURE / 解放军医学杂志

ABSTRACT

A new animal model of multiple system organ failure (MSOF) in rabbits is used in this experiment. The purpose of the current study is to observe dynamically the changes in the intestinal flora, the relationship between the changes and bacterial translocation to various organs and endotoxemia. The results show that there is no obvious alteration in population of Bacteroides, but a significant increase in enteric bacilli population in the contents of the ileocecum is found. Changes in the intestinal micro-flora correlate to the positive bacterial culture of the blood, viscera, and the level of endotoxin in the plasma. The results of our work suggest that ecological imbalance in the intestinal flora may promote-the gut-derived septic process and the development of MSOF.
