[The effect of the "37 degrees C--low pH" signal on cells of Yersinia pestis].

It is established that the synthesis of adhesion piles registered by the results of immunoenzyme analysis and immunoblotting starts 90 min after the action on apilated cells of plaque microbe EB-76 of the signal "37 degrees C-low pH" (cultivation at 37 degrees C and acidic pH). Under these conditions a part of cell piline is in a form connected with cells and only inconsiderable part (to 20%) is represented in a form of "classical" piles possessing hemagglutinating activity. It is shown that in first 7h after the interaction of the signal "37 degrees-low pH" synthesis of adhesion piles quantitatively prevails over the synthesis of antigen of the fraction I of plaque microbe.
