title: [Changes in membrane potential and transport of ions through the S. typhimurium LT2 membrane induced by bacteriophages].
abstract: Bacteriophages P22 and dp8 cause the membrane potential depolarization for 10-30 mV, reversal rapid H+ influx into bacteria and K+ exit from S. typhimurium LT2, these effects depend on infection plural and are observed only in the presence of Ca+2 in the medium. delta psi depolarization and K+ efflux induced by phage dp8 are increased with the growth of Mg+2 concentration from 0 to 2 mM. Changes of delta pH and also Na+,Ca+2 concentrations are not observed. In the presence of glucose phage infection leads to changes in H(+)-K(+)-exchange. The phages P22 and dp8 adsorption on bacteria causes changes in the form or turn of the channels in S. typhimurium membrane.
