[Biocenotic activity of salmonellae of rare groups]

The symbiotic activity of 69 Salmonella cultures of rare groups, belonging to the strains of different origin, with respect to pathogenic and nonpathogenic bacteria, bacilli, Staphylococcus aureus was studied. The study revealed that salmonellae of rare groups were capable of synergetic activity with respect to all test cultures used in this study. The spectrum and manifestation of this property were found to depend on the origin of the strains. The direction of the synergetic activity of salmonellae of rare groups, isolated from the environment, made it possible to suggest the importance of this sign for their survival under unfavorable environmental conditions. Close relationship between the synergetic activity of microorganisms and the clinical course of infection gave grounds for the conclusion on the pathogenic importance of this property and the necessity of its study in the evaluation of the pathogenic potential of microorganisms.
