[Electron microscopic study of the interaction between phages and Bacillus thuringiensis cells].
The interaction of phages belonging to different morphological groups with the cells of Bacillus thuringiensis var. galleriae R and S variants was studied. No adsorption of phages Tg11 and Tg18 on the cells of R variant was found upon infection in a liquid medium. What is characteristic of phage Tg11 is that it is predominantly adsorbed at the poles of S variant cells. Phage Tg18 particles are uniformly distributed along the perimeter of S variant cells. Phage Tg13 is adsorbed on the both variant cells. Phage aggregates with the elements of cell walls having a tetrahonal assembly of the subunits can be revealed in phage Tg13 lysates. The size of the subunits is 7 nm and the distance between their centers is 11 nm. A structured element, apparently the T-layer, is involved in the adsorption of phage Tg13 on the cells.
