Influence of biotic and abiotic factors on the epizootic process in salmonellosis in farm animals

Abstract

Salmonellosis is widespread in the world, including in Russia. Current preventive do not allow eliminating the disease completely. Successful implementation of measures to control salmonellosis is possible only when taking into account the peculiarities of the manifestation of the epizootic process in relation to certain natural, climatic and socio-economic conditions. It is advisable to use factor analysis to establish the influence of biotic and abiotic factors on the epizootic process. Factor analysis made it possible to establish a significant interaction between primary and secondary actuating conditions for the development of the disease. These factors were combined with the cyclical manifestation of the epizootic process. Factor analysis made it possible to establish that with an increase in the loading of parameters, the intensity of the epizootic process will rise. At average annual temperatures (-0.33°C - 1.78°C) and annual precipitation (446 mm - 628 mm), in areas with a higher than average level of livestock of animals, the incidence of cattle is likely to be up to 0.11%; the incidence of pigs – up to 1.39%; the incidence of birds – up to 0.06%. The established probabilistic forecast encourages the adoption of effective measures for the prevention of salmonellosis in farm animals.
