MULTIPLAN OF POPULATION OF CARRIER AS FACTOR OF ENZOOTY OF A PLAGUE (TAKING AS AN EXAMPLE TUVA NATURAL FOCUS)
In Tuva natural plague focus 3 groups of main carrier of ground squirrel are marked out. They are the nuclear of population, peripheral settles and nuclei of periphery. Nuclei of population play role of main source constantly feeding the focus with main carrier. They have no conditions for taking roots and active display of plague epizooties. Epizooties take place almost in unstable peripheral settlings, their intensiveness mostly depend on migration of animals from nuclei of population and periphery. Taking into consideration biological meaning of mechanisms of adaptative homeostasis concerning enzooty of plague nuclei of population provide stable character of epizootic process in peripheral settlings. Its relative constancy is supported by nuclei of periphery, which play role of compensating factors of enzooty of plague.
