Kurzfassung:
Tularemia is a zoonotic disease with a wide geographical dissemination, and its causative agent Francisella tularensis can be used as a bioterrorism agent. The aim of the study was to evaluate the use of a set of reagents “Erythrocytic immunoglobulin dry tularemia diagnosticum” (“DET-Ig”) with the help of control test strains and field material from natural tularemia foci. Materials and methods. Using the introduced erythrocyte diagnosticum, we studied the decontaminated cultures of test strains ( F. tularensis Miura, F. tularensis 55, F. tularensis Schu, F. tularensis 15 NIIEG, Brucella abortus 544, B. melitensis 16-M, B. suis 1330, and Yersinia enterocolitica 64, Y. enterocolitica 178, Y. enterocolitica 383) and environmental samples suspected of containing F. tularensis . Results and discussion. It has been proven that the developed diagnosticum is specific, sensitive, and easy to use for routine diagnostics of tularemia. In the course of laboratory tests of the experimental series of the DET-Ig reagent kit, the possibility of qualitative determination of the tularemia agent in bacterial cultures, biological material and environmental samples in the reaction of indirect hemagglutination was demonstrated. Comparison of the results of use of erythrocyte diagnosticum in liquid and lyophilized forms showed the advantages of drugs after lyophilization: the possibility of transportation and long-term storage at any temperature conditions in various climatic conditions; the setting of the reaction is possible without the use of special diluents. The guaranteed storage term is set for two years (observation period). The results obtained indicate the prospects of introducing the developed drug into healthcare practice.
