[Electron microscopic study of the dynamics of experimental pyocyaneus pneumonia in the presence of severe burn injury].

Under conditions of a severe burn trauma the experimental P. aeruginosa pneumonia is accompanied by marked destructive changes of all the elements of the hemato-aerial barrier and its increased permeability. At the same time, because of sharp inhibition of the intracellular lysis of bacteria in all elements of the pulmonary reticuloendothelial system, a long-term retention of the pathogenic microflora in the pulmonary tissue is observed. The combination of these factors results in microflora invasion of the blood channel of the lungs, and in this way the lungs acquire an important role as additional portals of entry of infection in severe burn trauma.
