[Artificial immobilization of the two-membered bacterial system Bdellovibrio bacteriovorus 109D--Escherichia coli B in polyacrylamide gel].
The interaction of a parasite with a host was studied in the two-membered bacterial system, Bdellovibrio bacteriovorus 109D and Escherichia coli B, immobilised in polyacrylamide gel (PAAG). The parasite localised inside the host cells was found to be more resistant to the toxic action of PAAG components than free B. bacteriovorus. The latter lost its mobility and was inactivated in the matrix of the carrier whereas the intracellular parasite had a normal cycle of development in the periplasm of the infected cells. The dynamics of B. bacteriovorus and E. coli incidence in the liquid phase and in PAAG granules was studied while the immobilised system was incubated. The interaction in the immobilised system could be intensified by growing more bacterial host cells in PAAG particles. The immobilisation was shown to favour the survival of the parasite and the host in the two-membered system.
