Non-Specific Prophylaxis in the Tien Shan High-Mountain Natural Plague Focus: Past and Present

Since 1943, in the territory of Kirgizia in the Tien Shan high-mountain natural plague focus, the methods and measures of non-specific prophylaxis, aimed at extermination of the main carriers, grey souslik, and elimination of vectors - the fleas, have been developed and implemented. Established has been the fact that subsurface application of pulicide inside the souslik holes is more efficient in the context of long-term suppression of focal epizootic activity, rather than the elimination of carriers themselves. Presently, for epizootic inter-phase (resting stage) maintaining local treatments with environmentally-safe pesticides in the areas of continuous plague agent persistence and epizooties activation are performed.
