Experimental model of dysentery
Abstract:
A method of producing experimental dysentery in rabbits has been developed. A prerequisite for this model is the fact that microscopic fungi eliminating biologically active substances are regularly found in the large intestine of man. Using a rubber probe, the large intestine of rabbits was preliminarily irrigated with the filtrate of the Aspergillus flavus fungus and subsequently, the suspension of a 24-hour culture of dysentery bacteria Shigella flexneri was administered. A specific pathological process characteristic of dysentery infection with positive pathomorphological, immunological and clinical manifestations developed in the experimental animals. The developed technique of the experimental dysentery model is easy to accomplish and can be widely used for the study of various problems of dysentery infection.
