Abstract

In an epizootological investigation of the natural focus, the main task is to elucidate the mechanism of turnover of the causative agent and its quantitative characteristics at different stages of the epizootic process. This is based on the features of biocenotic relations between blood-sucking arthropods and susceptible warm-blooded animals determining the composition of the parasitic system of the natural focus of human infectious disease. The population densities of both and different possibilities of simultaneous combined parasitizing of different vectors determine the greater or lesser degree of the probability of mediatory dissemination of the causative agent among susceptible animals in the territory of a natural focus (Ravdonikas et al., 1969a).
