ABSTRACT
The electron-microscopic study of the interaction of F. tularensis virulent and attenuated strains with infusoria of the species T. pyriformis was dynamically studied. In this study the structural changes of F. tularensis and T. pyriformis cells, as well as their capacity for survival, were revealed. The data on their ultrastructure correlated with the dynamics of the number of both F. tularensis and T. pyriformis: during the whole term of observation the tendency to a slow decrease in the number of F. tularensis was registered with the concentration of T. pyriformis remaining stable. The interaction of F. tularensis with T. pyriformis may be regarded as a variant of commensal, but not antagonistic interactions.
