The priority results of Russian researchers obtained over a 60-year period of studying Far Eastern scarlet-like fever (FESLF) are presented. It is proved that this previously unknown clinical-epidemical manifestation of pseudotuberculosis in medicine occurred as a result of the acquisition of special extrachromosomal genetic information (plasmid pVM 82) by the pathogen. FESLF was found to be associated with a specific clonal line of Yersinia pseudotuberculosis, extended in Russia. The results of a long-term study of DSL became the basis for revealing the fundamental issues of medical microbiology and ecology, namely: the concept of the psychrophilicity of pathogenic bacteria and the significance of this phenomenon in the epidemiology and pathogenesis of the diseases they cause, saprophytism and parasitism of pathogenic bacteria, as well as for the development of the doctrine of saprozoonoses (sapronoses) with identification of genetic and biochemical mechanisms of pathogenic bacteria adaptation to changing environmental conditions. The relevance of further research on the problem of FESLF is associated with establishment the significance of heteromorphism and persistence of Y. рseudotuberculosis in the interepidemic period.
