The authors studied the mechanisms of bacterial dissemination in opera
tive wounds in patients after various surgical interventions. It was d
emonstrated in experiments that during adaptation of the organism to t
he operative stress, autobacteria enter the blood from the intestinal
reservoir and are eliminated through the urinary tract and wound surfa
ces, if foci of mechanical or toxic destruction exist the autobacteria
precipitate in the affected tissues and participate directly in the r
eparative processes. On the basis of the obtained data it is suggested
that the phenomenon of activation and persistence of endogenous micro
flora exists as one of the syndromes of adaptation of man to the aggre
ssion factor, which is aimed at revealing and removing the foci of tis
sue destruction developing as the result of exposure to the effect of
the stress.
