The aim of the study was to assess the effectiveness of the developed anthrax magnoimmunosorbents (MIS) for the selective concentration of Bacillus anthracis spores and to increase the sensitivity of anthrax agent detection techniques, including when testing soil samples.Materials and methods. We used 10 vaccine strains of B. anthracis and 30 strains of closely related bacilli of the genus Bacillus (B. cereus – 15, B. thuringiensis – 10, B. megaterium – 5) with typical species properties. The work was performed on three experimental batches of magnoimmunosorbents. DNA extraction and PCR setting was carried out in compliance with the instructions for reagent panel for B. anthracis DNA detection “ApliSens Bacillus anthracis-FRT”.Results and discussion. It is shown that when using MIS, the sensitivity of the cultural method is increased by at least 7 times (taking into account the possibility of sorption of 1–10 or more spores on a sorbent particle). The sensitivity of the PCR method is improved by 10 times and amounts to 50 B. anthracis spores per 1 ml for the samples concentrated with the help of MIS. The sensitivity of the bacteriological method using MIS increases by a factor of 7.5 when testing the artificially contaminated with B. anthracis soil samples. Hence, application of the developed MIS makes it possible to significantly enhance the sensitivity of anthrax agent detection methods and can be considered as an effective means of sample preparation for the investigation of environmental objects (soil).

Health Risk Analysis

Over recent years there have been registered anthrax cases among animals and people in Russia. Anthrax cattle burials remain a basic risk factor that causes epizootic deterioration. A lot of such burials do not correspond to sanitary-epidemiologic requirements especially those located in zones where long-term frozen rocks are now being developed in the northern European part of the country. Our research goal was to examine a situation with anthrax cattle burials in the chosen regions, especially bearing in mind climatic changes and changes in cryolite zones as well as to assess future prospects regarding them. It is especially vital for native people who live in tundra and breed their numerous deer herds there. To achieve the goal, several tasks were accomplished. First, we performed preliminary analysis of anthrax cattle burials distribution in the northern European part of the country and places that were unfavorable as per anthrax. Then, locations of such zones were compared with available data on contemporary development of the cryolite zone in the northern European part of the country. It was necessary to assess future changes in the cryolite zone and describe occurring problems related to anthrax cattle burials being widely spread there as well as to suggest possible ways to solve them. Over the last 50 years considerable spots in the cryolite zone have thawed through completely or partially, especially in an area close to the south border of frozen earth. It is important to know an actual situation with anthrax cattle burials given changing climatic conditions and to assess their future prospects. In order to prevent emergencies in zones where geocryological processes have been activated it is necessary to measure temperature on anthrax cattle burials territories, to assess geocryological threats, to create mathematical models for probable negative events occurrence, as well as to accomplish certain anti-epidemic, anti-epizootic, and preventive activities.

The purpose of the study was to conduct a retrospective analysis of the epizootiologic and epidemiologic situation of anthrax in the Republic of Crimea and to improve surveillance of this infection using geographic information systems (GIS technologies). Material and methods: In the process of considering specific features of manifestations of infection in different areas of the Crimean Peninsula and outbreaks of anthrax in animals and humans in 1922–2019, we analyzed and summarized data of reporting forms of the Interregional Department of Rospotrebnadzor in the Republic of Crimea and Sevastopol. ESRI’s ArcGIS 10 software was used as a GIS-platform. When zoning the administrative units of Crimea by the level of endemicity, we estimated epizootic indices for anthrax. Results: We observed a relatively safe epizootiologic and epidemiologic situation of anthrax in the Republic of Crimea. In 1922–2019, 211 potentially hazardous stationary sites located in nine districts and one city council and 13 anthrax burial sites in four districts were registered in Crimea. Most sites (182 or 86.3 %) appeared in 1932–1961, the peak anthrax activity occurred in 1942–1951, and the latest outbreaks of infection among animals and humans were registered in 1995. Taking into account the ability of anthrax spores to persist in soil for years, the administrative units of the Crimean Peninsula were zoned using GIS-technologies based on the established epizootic indices. As a result, the territory of the Republic of Crimea was divided into areas with different levels of risk of exposure to anthrax. We also studied the relationship between the endemic areas and local climatic and geographical conditions and found that the majority of stationary sites (167) were within the dry-steppe, typical steppe, and northern steppe zones of the Peninsula with dominating soddy calcareous, meadow chernozem, and chernozem types of soil.
