In the Southeast agroclimatic area of the Nizhniy Novgorod region, the evolutionary formation and functioning of 51 parasitic systems have been retrospectively established, the co-actants of which, in addition to their pathogens, were productive and nonproductive domestic and wild animals. For the entire depth of retrospection (82 years), eleven nozologic units of contagious pathologies in the animals in the region (21.6 %) were found dominant in terms of both the number of epizootic foci and the number of infected animals (rabies, dictyocaulosis, infectious atrophic rhinitis, classical pig plague, piroplasmosis, salmonellosis, swine eruption, anthrax, fascioliasis, blackleg, and contagious aphtha). Their share in the nosologic profile of infectious pathology in animals was 241 epizootic outbreaks (68.5 % of the total number of the epizootic foci of infectious diseases in animals in the region at the depth of retrospection). At the same time, over the entire period of retrospection, 13 nosologic units in the studied area have been identified once, no extension of the boundaries of their epidemic manifestations has been identified, and the carry-over of the pathogen of these infectious diseases beyond the primary epizootic focus has been prevented. Relapses of their epizootic phenomena in the region have also been prevented. Ten nosologic units of contagious pathology in animals (18 %) in the total pathology in the animals in the studied area during the entire period of retrospection have been identified twice (chicken typhoid, pig and cattle taeniasis, pig metastrongylosis, infectious bovine rhinotracheitis, chicken ascaridiasis, cattle parainfluenza, Nosema disease).In the study zone, potential danger of spontaneous emergence and spreading of contagious diseases in animals (anthrax, blackleg, bovine tuberculosis, fascioliasis, classic and African swine fever, piroplasmosis, echinococcosis, and rabies) has also been identified. Schematic models of the potential threat of the epizootic component of the biological hazards in the region have been built. New scientific evidence has been obtained about the dynamics of the epizootic state of rural and urban areas in the region as the epizootic component of the biological hazard, about regional characteristics of the particular nosologic units of the contagious animal pathology, and their potential epidemic hazard in the region.
