title: [Dissociation of Pectobacterium carotovorum subsp. carotovorumrelated to the changes in the cell wall lipopolysaccharide].
abstract: It is shown for the first time that population heterogeneity of Pectobacterium carotovorum subsp. carotovorum is applicable to a wide range of strains and therefore is a universal characteristic. Using the method of specific selection with the help of carotovoricins which are identical to the phage tails a set of population dissociants of different types was obtained, due to the fact that S-LPS is the part of the cell wall which contains their attachment sites. It was determined that changes in S-lipopolysaccharides lead to the formation of SR-, R-forms of P. carotovorum. A suggestion is made that the changes in the surface structures of dissociants have a significant impact on secretion types II and III--the main pathogenicity factor of some bacteria. The results presented are a prerequisite for studying the direction, the reasons for dissociation process and its impact on the pathogenicity of P. carotovorum.
