The problem of rational use of mineral resources and mining waste in the context of sustainable development of regions

Efficient use and protection of the subsoil is a part of rational nature management in the mineral base of Ukrainian regions and Ukraine as a whole. The components for the rational use of the subsoil include a comprehensive development of mineral deposits, a comprehensive use of mineral raw materials and mining waste, optimization of the structure of mining production and mineral raw materials consumption. The rational use of mineral resources in the modern interpretation of this issue extends to all stages of their development, including the issue of waste disposal. A huge amount of mining waste has been accumulated in administrative regions of Ukraine, and the issue of their disposal has gone beyond just an economic and ecological problem and has acquired a significant socio-demographic significance. Environmental problems have become particularly acute due to the accumulation of toxic waste, among which the most dangerous are heavy metals, petroleum products and acid tars. For the sustainable development of Ukraine, it is necessary not only to develop new reserves of natural raw materials, but also technogenic minerals accumulated in more than 1,600 man-made deposits and objects. The further development of the mineral base requires, at the state level, an urgent solution to problems that hinder the development and ecological rehabilitation on the ground of rational use.

Problem issues regarding legal liability for environmental offenses in Ukraine

Purpose. To identify controversial and problematic provisions of the current legislation of Ukraine in the sphere of environmental protection which form the plane of legal responsibility for violations of environmental standards and norms. Methodology. The following research methods were used: the monographic method of scientific research, synthesis and analysis, the economic-statistical method, the method of detailing and concretizing the obtained results, the method of scientific-abstract systematization of results, and the graphic method of visualizing the results of scientific research. Findings. In Ukraine, a regulatory framework has been established that regulates the system of responsibility for environmental violations. Its main forms include disciplinary, administrative, civil, and criminal responsibility. It has been found that the modern environmental legislation is characterized by certain shortcomings in the identification and prosecution of persons guilty of violating the norms of existing laws. This is confirmed by the analysis of the amount of damage and losses caused to the environment, the dimensions of which are increasing annually in Ukraine. Simultaneously with the increase in the amount of damage caused, the degree of non-identification of persons who are responsible for causing damage to natural resources and the environment is increasing. The analysis of regional differences in environmental responsibility also demonstrates significant differences between the administrative regions of Ukraine in terms of the discipline of environmental responsibility. Originality. Based on the results of the conducted research, the main problematic aspects regarding legal responsibility for violations of environmental legislation in Ukraine were identified and analyzed. A need for a fundamental change in the concept of environmental responsibility for economic entities within the framework of sustainable development strategy has been identified. A gradual change in the basic principles and approaches to responsibility for violations of environmental legislation in the direction of predominance of preventive functions of environmental protection over punitive ones was proposed. Tools for possible improvement of environmental legislation were also proposed, in particular, fiscal preferences for environmentally tolerant industries, application of trade quotas for industrial enterprises that pollute the environment, harmonization of sanctions and environmental tax rates in accordance with the legislation of European countries. Practical value. The research results and proposed measures for improving the current procedures and mechanisms of legal liability for environmental offenses can be used by specialists of legal departments and services at the level of micro-management and macro-management to solve the tasks of further improvement of the current legal framework and increase the level of social responsibility of business and officials.

A review of the genus Amischa Thomson, 1858 (COLEOPTERA, STAPHYLINIDAE: ALEOCHARINAE) of Ukraine

The work summarizes information about the finds of species of the genus Amischa based on the study of collections stored on the territory of the country, collected in different administrative regions of Ukraine and the Autonomous Republic of Crimea. As a result of the research, it was established that the genus Amischa is represented in Ukraine by four species (A. analis, A. bifoveolata, A. decipiens, A. nigrofusca). Data on ecological features and distribution of the identified species are presented. The obtained results can be used to solve a number of theoretical issues of fauna, zoogeography and ecology, as well as in the preparation of the fauna cadastre of Ukraine, for comparative faunal studies, analysis of the distribution of species, biogeographic structures, study of faunogenesis, ecological monitoring and forecasting of the consequences of human activity on the natural ecosystems of the region.

Environmental and economic prerequisites of amber mining in Ukraine

The negative consequences of illegal amber mining lead to damage to the country's economy and the destruction of the ecosystem in those regions where intensive mining is conducted. The article is devoted to a comprehensive consideration of the issue of illegal amber mining. The ecological and economic prerequisites for the emergence of the problem of illegal mining are given, and its main ecological, economic and social consequences are also determined. It is argued that the illegal actions of prospectors and their consequences continue to be a painful issue in the socio-economic life of Ukraine, from which not only the natural environment, but also the economy of Ukraine suffers. As a result of the uncontrolled extraction of precious stones, the actions of criminal groups smuggling them abroad, the state will not receive millions of hryvnias from the state budget. The calculation of Ukraine's annual losses from illegal amber mining and sales is presented. The distribution of reserves and extraction of amber by administrative regions of Ukraine was analyzed. It is noted that there are two direct payments related to amber mining: a fee for a special permit for the development of the site and mining, as well as rent - a share of the income from the sale of precious stones. Generalized data on the formation of amber deposits and mining taxation processes in Lithuania and Poland are provided. The dynamics of selling prices of Ukrainian and Polish amber is presented, a significant drop in the price of Ukrainian raw amber compared to 2016 was established. The problem of illegal mining in forest areas in the north-west of Poland has been studied. It is noted that amber prices are constantly changing depending on the fractions, but the introduction of a single fixed rate will contribute to the development of this industry.

Закономірності прояву фізичної деградації в орних ґрунтах України та регіони підвищеного її ризику

Goal. To study the patterns of physical degradation in arable soils of Ukraine, and identify its features in different climatic zones, as well as to identify regions of increased risk of its manifestation and propose efficient anti-degradation measures. Methods. Information-analytical — to analyze the literature on physical degradation of arable soils; mathematical and statistical — to identify the reliability of the results and calculate the area of soils at risk of physical degradation; cartographic — to create cartographic materials to identify problem areas of physical degradation. Results. The main reasons for the spread of physical degradation of arable soils were identified: the increased tendency of humus to mineralization and mobility, over compaction and destructurization, increase in the number of large and small pores in macroaggregates. The peculiarities of the manifestation of physical degradation of soils depending on the natural and climatic zone of their location are characterized. Based on the creation and analysis of cartographic materials, problem areas with physical soil degradation were identified and their areas were calculated by administrative regions of Ukraine. It is established that the soils of the Kherson region are characterized by the greatest tendency to the manifestation of physical degradation. Also, regions with an increased risk of physical degradation in soils are Zaporizhzhia, Poltava and Kyiv. The principles of overcoming physical degradation are determined, effective anti-degradation measures are proposed, the main ones of which are minimization of mechanical impact on the soil, observance of the deficit-free balance of organic matter and preservation of the agronomically useful structure. Conclusions. The causes and consequences of the physical degradation of arable soils are outlined. The urgency of identifying areas of soil susceptibility to physical degradation is proved, the peculiarities of its manifestation in different climatic zones of the country are analyzed. The main means and principles for overcoming the physical degradation of soils are proposed.

A geographical dimension of resource endowment of Ukrainian territories


 
 
 Given the multidisciplinary nature of this research, it is important to develop a common understanding of the security and complexity of the rational consumption of available minerals. Considerations for the availability and depletion of minerals are part of a diverse range of research focused on sustainable development, in areas such as resource critical shortage, life cycle assessment and material flow analysis. Mineral resources are non-renewable resources that provide humanity with a wide range of goods and services. Although their value has been recognized for millennia, their large-scale industrial production did not grow until after World War II due to efficient industrial production processes and rapidly growing demand due to demographic growth, urbanization and economic wealth growth in developed countries. The proposed research confirms the high level of supply of the territory of Ukraine with mineral resources. The objective idea of mineral and self-sufficiency of Ukraine, its inclusion in the top groups of the states most provided with the most valuable types of minerals is strengthened and the high level of availability of mineral resources in Ukraine in terms of its economic and geographical areas and regions is confirmed. At the same time, a number of mineral deposits in modern social and economic conditions are preserved and not used. For the first time, a cartographic interpretation of the periodic table of chemical elements (D. I. Menedeleev's table) is given, which is reinforced by data on the distribution of mineral resources and minerals in terms of selected groups of regions within the administrative regions of Ukraine. There are 33 chemical elements extracted from more than 100 mineral deposits. The provisions and conclusions of the article testify the mineral self-sufficiency of Ukraine and can act as a lever for developing strategies for socio-economic development of the United Territorial Communities (UTC) of Ukraine, which today are the new centers of management of territories and its resources. D. I. Mendeleev's table and its mineral content are positioned as an objective factor in the specialization of Ukraine and the international geographical division of labour. It is noted that the main advantages of the Periodic Table of Chemical Elements, including its structure, logic, objectivity, a system in relation to the economic and geographical regions of Ukraine are considered as an element of monitoring the mineral component of natural resources of the country, the lever of further development of exploratory geology and geomorphology. The information obtained from this research ultimately influences the future policies of the territories and its plans for the balanced use of available mineral reserves and can be used to promote the sustainable use of mineral resources in the regions.
 
 

Metagenomic analysis of individually analyzed ticks from Eastern Europe demonstrates regional and sex-dependent differences in the microbiota of Ixodes ricinus

Understanding the microbial ecology of disease vectors may be useful for development of novel strategies aimed at preventing transmission of vector-borne pathogens. Although Ixodes ricinus is one of the most important tick vectors, the microbiota of this tick has been examined for only limited parts of the globe. To date, the microbiota of I. ricinus ticks collected from Eastern Europe has not been defined. The objective of this study was to compare microbiota of I. ricinus ticks within (males vs. females) and between collection sites that represented three administrative regions of Ukraine, Dnipropetrovs'k (D), Kharkiv (K), and Poltava (P). A total of 89 questing I. ricinus adults were collected from region D (number of ticks, n = 29; 14 males and 15 females), region K (n = 30; 15 males and 15 females) and region P (n = 30; 15 males and 15 females). Each tick was subjected to metagenomic analysis by targeting the V6 region of 16S rRNA gene through the Illumina 4000 Hiseq sequencing. The alpha diversity analysis demonstrated that, regardless of tick sex, patterns of bacterial diversity in ticks from regions K and P were similar, whereas the microbiota of region D ticks was quite distinct. A number of inter-regional differences were detected by most beta diversity metrics for both males and females. The inter-regional variations were also supported by the principal coordinate analysis based on the unweighted UniFrac metrics with three region-specific clusters of female ticks and one distinct cluster of region D males. Lastly, numerous region- and sex-specific differences were also identified in the relative abundance of various bacterial taxa. Collectively, the present findings demonstrate that the microbiota of the I. ricinus tick can exhibit a high degree of variation between tick sexes and geographical regions.

Monitoring of Human Development in Regions of Ukraine (Integrated Approach)

The article summarizes the basics of information and methodological metrology of regional human development, the formation and development of which were approved by the Government of Ukraine in 2001, 2012 and 2017. Particular attention is paid to the problems of coordination of the assessment of the dynamics of the components of the Regional Human Development Index (RHDI) with the indicators of the National Regional Development Strategies for the periods up to 2015, 2020 and 2027. In the context of assessing the effectiveness and efficiency of the mechanism of state regulation of regional human development on the basis of its forecasting revealed the essence and content of the 4 stages of the algorithm of comprehensive rating assessment of RHDI. Methods of clustering of regions by appropriate components, methods and procedures of composition and decomposition of components of RHDI were used in order to ensure socio-economic security of regions. Differentiation of the system of indicators and procedures for monitoring regional human development at the subnational (regional) level allows to more objectively determine the socio-economic policy of regional and local executive bodies to improve the quality of life of villages, towns, cities, districts and administrative regions of Ukraine.

From the revolution of dignity to despair: a reflection on the border regions of Ukraine

This article offers a detailed analysis of the content characterising the geopolitical challenges and socio-economic changes that have been facing Ukraine in the years following the Revolution of Dignity, as well as interregional differences. The focus here is on administrative regions of Ukraine that border on to EU Member States, while the special emphasis is on the Ukrainian-Polish border regions, i.e. those in which the cooperation put in place can be regarded as most successful and intensive of all. Furthermore, as gaps to the availability of statistical data are present, the main emphasis has been on case studies, content and SWOT analysis, the search for good practice, and typical patterns of perception as markers of the dynamics present in social space.

Intersectoral component of the structural and functional management model: a methodology for developing regional prevention programs and evaluating its effectiveness (for example, the child population of certain administrative regions of Ukraine)

Modern ideas about comprehensive assessments of the level of health are based on synthetic (complex, integral, multidimensional) indicators, the requirement for which is the need to take into account various (by origin and methods of obtaining) health indicators both at the individual and population, regional levels. In recent years, many methodological methods have been processed to obtain a comprehensive qualitative and quantitative assessment of the state of individual health. Obtaining a generalized qualitative and quantitative assessment remains the most important methodological task of modern theory and practice of public administration and public health. The purpose of the study was to develop a methodology for substantiating intersectoral regional prevention programs and an algorithm for evaluating their effectiveness using the example of a dysplastic-dependent pathology of the bronchopulmonary system in children. In developing and justifying population-based management models for early diagnosis and primary prevention, we used systematic population modeling methods. The expected indicators of the pathogenic and sanogenic effects of the most significant regional and environmental factors of the dysplastic-dependent pathology of the bronchopulmonary system among children are determined. Substantiated models of end results for modification of risk factors and the expected effectiveness of the N-factor regional and environmental program for the primary prevention of dysplastic dependent pathology of the bronchopulmonary system in children. Priority areas for the implementation of regional-population programs for the prevention of dysplastic-dependent pathology of the bronchopulmonary system in children due to the impact on controlled environmental environmental factors are determined. An example of calculating the expected effectiveness of children's health management through interdepartmental interaction at the regional level is given. Prospects for further research on this issue related to a prospective evaluation of the effectiveness of intersectoral programs to reduce the influence of regional environmental factors on the health status of the child population, in particular, dysplastic-dependent pathology of the bronchopulmonary system.

Оцінка рельєфу території Чернігівської області для цілей рекреації і туризму

The paper analyzes the features of relief assessment as one of the main natural and recreational resources of the territory. It is shown that the main morphometric properties of the relief most objectively characterize the recreational properties of the territory at the regional and local levels. Important characteristics of a certain area depend on them: accessibility, visibility, diversity, natural attractions (rock outcrops, outcrops, rocks, caves, etc.).For a health-improving solution and tourism, both functionally and naturally are the most friendly of humpbacks, even with minor changes. Rivna, flat surface is unpleasant, splinters from the point of view of the aesthetics of landscape photography, the monotonous relief is not tsikaviy, but also functionally of little adherence. It is given an integrated assessment of the relief of Chernihiv region territory for recreation and tourism. The general degree of favorable geological and geomorphological conditions for recreational activities is determined by a combination of two indicators: the complexity of the terrain and the presence of geological and geomorphological natural attractions. To determine the complexity of the relief, the analysis of morphometric indicators of the relief within the Chernihiv region administrative-territorial systems was carried out. Instead of traditional morphometric parameters, such as the density of dismemberment, the depth of dismemberment and the slope of the earth’s surface, a synthetic characteristic is studied in detail - an indicator of the intensity of erosion dismemberment, which fully reflects the main external features of the earth’s surface. To determine the recreational value of natural attractions, the number of geological and geomorphological protected objects (national nature parks, landscape reserves, complex and geological natural monuments of national and local importance) for each Chernihiv region administrative-territorial system was estimated. To analyze the obtained results, the method of scoring is used. It is the most accurate in the analysis of indicators presented in different measurement systems. It is established that the most favorable for the development of recreational activities, in geological and geomorphological terms, were the territories of Varva, Sribne and Talalaivka districts (primarily due to the complexity of the relief - 9 points), as well as Ichnia, Korop, Novgorod-Siversky districts, where geological and geomorphological protected sites (8-10 points) played a role.Indicators in most districts of Chernihiv region are from 3 to 5 points, which indicates a rather low favorable geological and geomorphological conditions for the development of recreation within the study region. Highlighting the tourist and recreational potential of the Chernihiv region will contribute to the development of tourist infrastructure, expansion of the tourist business and improve the level of service.The theoretical analysis of the algorithm of the recreational assessment of the minds of the relєfu can be victorious during the development of the program for the development of recreation in the boundaries of the territory of the natural reserve fund. Given the robot can be the basis for a similar assessment of the minds of the administrative regions of Ukraine with the method of effective tourist and recreational activity.

Projected distribution of the warm season droughts over the territory of Ukraine in 2021-2050

Introduction. Drought is a natural phenomenon that occurs in all climates, and is one of the most relevant natural hazards, which propagates through the full hydrological cycle and affects large areas, often with long-term economic and environmental impacts. A prolonged deficit in precipitation over a defined region cause a meteorological drought, while the other types of drought describe secondary effects on specific ecological and economic compartments. Recent trends in the drought distribution and intensity shows that Europe splits into two big areas, in which the southern and western regions have positive trends of drought frequency, duration, and severity, and the northern and eastern regions show a decrease in this parameters. Regarding the long events, territory of Ukraine belongs to the areas in which a prominent decrease in drought frequency, duration and severity are fixed. But positive trends in the drought characteristics are observed on the Black Sea coast, also in the Carpathian region, many droughts occurred in the past three decades. The purpose of this study to examine the results of analysis of the spatiotemporal distribution of warm season droughts (April-October) across the administrative areas of Ukraine in 2021-2050 under the climate scenarios RCP4.5 and RCP6.0 with them comparing. Data and methods. Drought estimation was performed using the SPEI index (the Standardized Precipitation Evapotranspiration index). The inclusion of temperature through the potential evapotranspiration (PET) along with precipitation data allows SPEI to account for the impact of temperature regime on a drought situation. A drought episode for given time scale is defined as a period, in which SPEI is continuously negative and reaches a value of –1.0 or less. In this study, the gridded fields of monthly air temperature and precipitation intensity from multimodel sets of global CMP5 models are taken for calculations of SPEI. Data access was made through the Climate Explorer. All data were averaged over the area of each of 25 administrative regions of Ukraine. Research results. Analysis of the time series of the calculated SPEI index for both scenarios showed that in all regions of Ukraine there will be a tendency to transition from moderately wet conditions in 2021-2035 to droughty conditions in 2037-2050. In the first half of the study period drought is expected near 2024, as well as in 2030-2033 almost in all provinces except southern areas. In the second half of the period prolonged seasonal drought is projected in 2044-2047 over all Ukraine and in some areas drought may reach an extreme intensity. Decade analysis of the SPEI7 time series showed that in both scenarios in all regions of Ukraine, the least number of dry seasons is expected from 2021 to 2030. The highest number of dry seasons in this period may reach up to 4-5 cases per 10 years in the western regions under RCP6.0 scenario. In other regions the number of dry warm seasons will be 2-3 cases per 10 years. In the period from 2031 to 2040, the number of dry seasons will increase substantially in all regions of Ukraine under RCP4.5 scenario, in which their number will be 5-6 cases per 10 years. Under RCP6.0 scenario, an increase in the number of droughts will be observed in all areas except the western regions, where will be from 2 to 4 dry seasons per 10 years. In the last decade from 2041 to 2050, in both scenarios, the number of dry seasons will increase throughout Ukraine compared to the previous decade. Under RCP6.0 scenario, the greatest increase is projected in the north of the country and in some other regions throughout Ukraine, where the maximum number of seasons with droughts will reached up 8-10 cases per 10 years. Conclusions. Comparison of the SPEI7 time series for both scenarios showed that under RCP6.0 scenario the transition from wet conditions to dry conditions is projected during long period from 2030 to the early 2040s. In this time, small interannual variations of the SPEI index across all regions are expected, and only in the last decade the dry seasons will prevail. In addition, in the RCP6.0 scenario, maxima of drought frequency are expected in few different regions of the country, compared with the RCP4.5 scenario, which indicates significant scenarios' differences in the predicted state of the regional atmospheric circulation determined the temperature and precipitation regimes in the future.

Analysis of regional development disparities in Ukraine with fuzzy clustering technique

Disparities in the development of regions in any country affect the entire national economy. Detecting the disparities can help formulate the proper economic policies for each region by taking action against the factors that slow down the economic growth. This study was conducted with the aim of applying clustering methods to analyse regional disparities based on the economic development indicators of the regions of Ukraine. There were considered fuzzy clustering methods, which generalize partition clustering methods by allowing objects to be partially classified into more than one cluster. Fuzzy clustering technique was applied using R packages to the data sets with the statistic indicators concerned to the economic activities in all administrative regions of Ukraine in 2017. Sets of development indicators for different sectors of economic activity, such as industry, agriculture, construction and services, were reviewed and analysed. The study showed that the regional cluster classification results strongly depend on the input development indicators and the clustering technique used for this purpose. Consideration of different partitions into fuzzy clusters opens up new opportunities in developing recommendations on how to differentiate economic policies in order to achieve maximum growth for the regions and the entire country.

Evaluation of the influence of climatic and geomorphological factors on landslides development

The paper deals with the study of factors influencing the propagation of landslides in Ukraine. According to numerous monitoring studies, climate changes have significant impact on the stability of natural slopes and cause landslide processes. The topicality of the study is connected with the multifactor mechanism of landslides formation and complexity of this process development in space and time scales. Activation of landslides is registered on the territory of almost all administrative regions of Ukraine. The increasing dependence of the number of recorded landslides on annual precipitation and relief is established. For the most landslide-prone regions of Ukraine, the integral coefficients of the relief influence have been calculated, and the levels of potential landslide risk have been determined. Linear regression dependence between the amount of atmospheric precipitation and the number of landslides has been obtained, which allows predict landslide hazard in the regions of Ukraine. The results of the calculations are presented graphically in the form of a map.

Epidemiology, etiology and gene analysis of spike S protein of porcine epidemic diarrhea virus infection in Ukraine during 2016–2017

The spread of PEDV of pigs continues in various countries and regions of the world. PED was first registered in several areas of Ukraine in 2014. At present, there is a limited number of publications on the characteristics of the spread of the virus infection in Ukraine. Moreover, obtained research data do not clarify the epizootic situation as a whole. Having regard to the state of pig farm industry and permanent growth of losses caused with PEDV infection, the study of PED in Ukraine is relevant and important. Therefore, the goal of the work was to clarify the epizootic situation of PED in various areas of Ukraine. We studied the epizootic state of PED with a typical course in pig farms and the made a primary assessment of the relation of genetic groups between identified pathogens from distinct regions of the country where the highest intensity of the epizootic process was determined. The work was carried out in the Biosafety Center (Ukraine). To determine the epizootic situation of PED during ‎2016–2017 we collected samples of the blood serum and biological materials from pigs from 105 agricultural enterprises that are located in 85 administrative regions of Ukraine. In total we tested 543 serum samples and 591 samples of pathological tissues. The detection of PEDV was performed by PCR-RT. Serological diagnostics were tested with ELISA. Sequence analysis was performed according to Sanger. The results of sequences were analyzed in the FinchTV / Chromas program. The analysis of the epizootic features of PED in different areas of Ukraine for ‎2016–2017 established that PEDV is the main causative agent of the infection. An infection circulates among sensitive animals in pig farms and induces PED, which is difficult to control and weakly managed as a particularly dangerous emergent infectious disease of pigs. In 2016, 6.5% of administrative districts located in 12 of the 25 regions of Ukraine were included in the study, and in 2017, 10.8% of administrative districts located in the 14 regions of the 25 regions of the country were investigated. In general, during 2016 and 2017 1134 samples of blood serum and animal tissue were collected from 105 agricultural enterprises from 17.3% of the administrative regions of Ukraine. The obtained results showed that in 2016 PED was registered in 7 administrative districts from 4 regions of Ukraine, and in 2017 the infection was registered in 2 regions. The results of RNA sequence analysis of the PED virus identified the characteristics of the PEDV genes which reflect a high degree of homology with the Chinese strain BJ-2011-1. The analysis of the obtained results revealled the relation of PEDV circulating in Ukraine to the strains identified in the USA. Moreover, the samples of PEDV from Ukrainian pig farms have the sequences that belong to the North American clade II from the group of 2 strains of the PED virus. However, the PEDV observed in Ukraine is different from them by at least one nucleotide replacement of the gene which codes a protein of the S domain. Based on the obtained results, it can be assumed that in Ukraine the PED virus could have spread from East Asia.

Study of Lyme borreliosis in Ukraine

Cases of human Lyme borreliosis (LB) are registered in all administrative regions of Ukraine and in the Autonomous Republic of Crimea with an increasing tendency. The hard tick Ixodes ricinus was proved as the main vector of Borrelia burgdorferi s.l., the causative agents of LB. We identified active natural LB foci, in which almost 25% of the adult I. ricinus ticks contained borrelias and more than 30% of the human population were seropositive for Lyme borreliae. The role of Mus musculus, Microtus arvalis, Myodes glareolus, Apodemus agrarius, and A. sylvaticus in the transmission cycle of the LB agent(s) was revealed. Combined foci and cases of LB/TBE (tick-borne encephalitis) mixed infection were registered in 8 oblasts. A considerable spectrum of different clinical manifestations of LB has been found including erythema migrans in 64.9% of cases, neurologic symptoms in 26.1%, rheumatic affliction in 24.7%, and cardiovascular problems in 8.3%.
