Abstract

Functioning of 51 parasitic systems has been retrospectively ascertained in the South-Eastern agroclimatic zone of Nizhny Novgorod Oblast, their co-agents, apart from their excitants, being productive and non-productive domestic and wild animals. For the entire depth of retrospection (82 years) eleven nosounits of infectious pathology in the region (21.6%) dominated in the quantity of epizootic foci and diseased animals (rabies, dictyocaulosis, infectious atrophic rhinitis, classical pig plague, pyroplasmosis, salmonellosis, swine erysipelas, anthrax, fasciolasis, blackleg, aphtha). They accounted for 241 episootic foci in the nosological profile of infectious pathology (68.5% of the total quantity of animal infectious disease epizootic foci in the region throughout the retrospection). At the same time, 13 nosounits in the investigated territory were registered only once during the entire period of retrospection, no expansion of the boundaries of their epizootic manifestation was ascertained, and carryover of the excitant of these infectious diseases beyond the limits of the original epizootic focus was prevented. Relapses of their epizootic occurrences in the region were prevented as well. Ten nosounits of animal infectious pathology (18%) in the aggregate animal pathology in the examined region during the entire period of retrospection were registered twice (hen typhus, swine and cattle taeniasis, swine metastrongylosis, contagious cattle rhinotracheitis, hen ascaridiasis, cattle parainfluenza, bee nosematosis). In addition, potential danger of animal infectious pathology spontaneous emergence and expansion was revealed in the South-Eastern zone of Nizhny Novgorod Oblast (anthrax, blackleg, cattle tuberculosis, fasciolasis, classical and African pig plague, pyroplasmosis, echinococcosis, rabies). Schematic models of the biological hazard epizootic component potential threat in the region have been designed. New scientific data have been obtained about the epizootic condition dynamics of rural and urban territories in the region as a biological hazard epizootological component, about regional peculiarities of animal infectious pathology specific nosounits, about their potential epidemic danger in the region.
