[Pathomorphology of toxico-infectious shock in influenza and leptospirosis]

Examinations of the section material of fatal cases due to leptospirosis and influenza, as well as examinations of organs in experimental toxic influenza by light and electron microscopy with determinations of the infectious and immune complexes showed leptospira and influenza virus to be capable of causing toxico-infectious shock (TIS) with typical changes in the microcirculatory bed and organ parenchyma. TIS should be considered to be a special form of the course of an infectious process in which different organs may be "shock organs" depending on the tropic properties of the causative agent: in leptospirosis - the kidneys and liver, in influenza - the lungs and brain.
