EFFECT OF SOIL COVER PATTERN ON EPIZOOTIC INTENSITY OF CATTLE DISEASES IN THE ALTAI REGION
A property developed by causative agents of infectious diseases with the evolution to be excreted from an organism of the infected host and to live through a certain period of the activity in the external environment does not complete their existence with a diseased organism, but enables their indirect or direct transmission to another organism. The research purpose was to define the extent of the effect of such natural factors as the mechanical composition of various soil types on the causative agents of infectious diseases. The mechanical composition of various soil types was chosen as a determining factor to reveal the dependence of active development of epizootic process in the Region in terms of soils, and the correlation analysis defined the extent of the effect. The maximum difference in the extent of manifestation was defined for pasteurellosis and anthrax by 9 and 10 times respectively with minimum values on loamy pulverous and maximum values on gravelly soils. Virosis manifestation at infectious rhinotracheitis was 14 times more intensive on gravelly soils compared to clayed and loamy soils. The data of factorial load was used when modeling an epizootic process for individual nosological entities, besides, the obtained results may be used to identify the areas where a large-scale cattle breeding would be the most effective.
