The current state and the main trends in the development of geographical information systems in the U.S.S.R

The paper falls into two parts. The approach to geographical information systems (GIS) in the U.S.S.R. and differences in terminology are first discussed. The main part of the paper comprises case studies on the design, construction and use of GIS and of computer-assisted cartography in the U.S.S.R. to illustrate the transition to the introduction of automated technologies to processing of geographical data for science, practice and education, the diversity of contexts, the problems tackled and their departmental attribution, and the territorial span, functional capabilities and technological equipment. The following trends of these developments are identified: the design of integrated GIS, an increase in their capabilities for modelling, the introduction of elements of expert systems, an orientation towards microcomputer technology, an awareness of the need to use standardized hardware and software (including linguistic terms) and a greater interest in the commercial and legal problems of GIS, international collaboration and education. © 1989 Taylor & Francis Group, LLC

GEOINFORMATION TECHNOLOGIES IN THE PROMOTION OF TOURIST DESTINATIONS IN THE ZONE OF THE GREAT SILK ROAD

To date, travel portals represent the most promising tool for promoting tourist destinations. Compared to traditional print media, their main advantage is the ability to access a wealth of information, services, to make online reservations, to create package-tours, and to obtain interactive representation of tourist sites. The paper discusses tourism demand for destinations of the zone of the Great Silk Road applying key statistics of the Yandex search engine queries. A comparative analysis of tourist destinations portal data has been conducted based on the following criteria: availability of multilingual information, interactive maps, selfguided tour planners, and information about attractions, tours, and accommodation facilities. In order to attract a large number of tourists and to successfully implement the project “Silk Road,” it is necessary to establish a common trans-national tourism portal which would include information on tourism opportunities in all countries

The article presents results of the multi-scale analysis of the processes of coronavirus infection spread and its impact on the demographic situation in the world, Russia and regions of the South of the European part of Russia. The methodological basis of the study was the principles of geoinformation monitoring, making it possible to process and visualize large volumes of diverse materials. The information base was statistical data from the Russian and foreign sources reflecting the spread of coronavirus infection at various spatial levels from global to regional-local. The characteristic features of changes in the parameters of the disease during its active expansion are described. The article also deals with dynamics in demographic indicators and identifies trends in their widespread deterioration. The contribution of the South of European Russia macro-region to the all-Russian Covid-19 situation is determined. Development of the coronavirus pandemic at the level of municipal districts is analyzed using individual regions as an example. The study identifies main factors of the Covid-19 pandemic development and demonstrates some of its features and consequences in the largest urban agglomerations

Detection of Babesia and Anaplasmataceae bacteria in small mammals from Irkutsk and Novosibirsk regions

Tissue samples from 228 small mammals captured from 2013 to 2015 in four districts of Irkutsk region and in one district of Novosibirsk region were examined for the presence of Anaplasmataceae bacteria and Babesia parasites by nested PCR method with subsequent sequencing of positive samples. In Ekhirit-Bulagatskiy District of Irkutsk region, Babesia microti DNA was found in 10.9 % of small mammals, Anaplasma phagocytophilum DNA - in 7.3 %, and Ehrlichia muris DNA - in 1.8 %. Infected mammals were not found in the other three examined districts of Irkutsk region. In Novosibirsk region, B. microti DNA was found in 8.9 % of small rodents, A. phagocytophilum DNA - in 8.9 % of small mammals, and Candidatus Neoehrlichia mikurensis DNA - in 8.9 % of small mammals. The identified infection agents corresponded to microorganism species and genetic variants previously found in Ixodes persulcatus ticks but not in ticks of other species

Identification of the etiological agent of equine piroplasmosis in Western and Eastern Siberia

Equine piroplasmosis is a natural tick-borne infection caused by hemoprotozoan parasites of the order Piroplasmida, Babesia caballi and Theileria equi. Animals that recover from piroplasmosis remain persistently infected carriers and can transmit pathogens to vector ticks. Cases of equine piroplasmosis are periodically observed in Siberia, however, no agent of equine piroplasmosis has yet been genetically characterized in Russia. The aim of this work was studying the prevalence of the infectious agents of piroplasmosis in horses from Siberia and genotyping the detected agents. Blood samples from 155 horses were examined for the presence of Babesia and Theileria DNA by nested PCR with the subsequent sequencing of positive samples. DNA of T. equi was found in blood samples from 57.9 %, 38.5 % and 65.0 % of horses from Novosibirsk province, Irkutsk province, and the Republic of Altai, respectively. T. equi DNA was found in the samples from almost all sampling sites included in this study, indicating that most of the studied sites are endemic for equine theileriosis. Surprisingly, DNA of B. caballi was not found in any of the samples examined, even though this agent had previously been detected in many regions in Russia, including Altai. The analysis of the determined 18S rRNA gene sequences demonstrated that T. equi samples belonged to two genetic groups, which differed significantly by the sequences of the variable (V4) region of the gene. All T. equi sequences from group B were identical and corresponded to T. equi sequences found in the blood of horses from China and Korea, while T. equi sequences from group A differed by 1–5 nucleotide substitutions and were identical to the sequences from the blood of horses from India and Brazil or differed from them by single mismatches. Notably, in this study the presence of etiological agent of piroplasmosis in blood samples from horses in Russia was genetically confirmed for the first time

Genetic heterogeneity of <i>Rickettsia helvetica</i> population

Background. To date, the genetic variability of Rickettsia helvetica has not been sufficiently studied.The aim. To study the prevalence and genetic variability of R. helvetica in Ixodes spp. collected in Western Siberia and the Russian Far East.Materials and methods. Ixodes  spp. collected from rodents in the Omsk province, Western Siberia (n = 280) and collected by flagging on Putyatin and Russky Islands in Primorsky Krai, Russian Far East (n = 482) were analyzed for the presence of Rickettsia spp. All positive samples were genotyped for the gltA gene fragment. For a number of R. helvetica samples, fragments of the 16S rRNA, ompA, ompB, sca4, htrA, and groEL genes and 23S–5S intergenic spacer were additionally sequenced.Results. Four Rickettsia species (R. helvetica, “Candidatus Rickettsia tarasevichiae”, “Candidatus Rickettsia uralica”, and “Candidatus Rickettsia mendelii”) were found. Of them, R. helvetica was identified in 72.2 % of Ixodes apronophorus and 18.8 % of  Ixodes trianguliceps from the Omsk province and in single Ixodes persulcatus from the Omsk province and Putyatin Island. This is the first finding of Rickettsia spp. in I. apronophorus. All known R. helvetica sequences from this study and the GenBank database belonged to four well supported monopheletic groups forming genetic lineages I–IV. Lineage I included European isolates from Ixodes ricinus, Western Siberian isolates from I. persulcatus, and some sequences from I. apronophorus. All R. helvetica sequences from I. trianguliceps from the Omsk province and I. persulcatus from  the  Komi Republic and one sequence from I.  apronophorus were assigned to  lineage  II. Most sequences from I.  apronophorus formed lineage  III; all known R. helvetica sequences from I. persulcatus from the Far East formed genetic lineage IV.Conclusion. The genetic heterogeneity of R. helvetica population was first demonstrated. Known isolates of R. helvetica are reliably assigned to four genetic lineages, but not in all cases the association of different lineages with a specific tick species or specific territory was observed

Characterization of the complete genome sequence of the recombinant norovirus GII.P16/GII.4_Sydney_2012 revealed in Russia

Noroviruses (the Caliciviridae family) are a common cause of acute gastroenteritis in all age groups. These small non-envelope viruses with a single-stranded (+)RNA genome are characterized by high genetic variability. Continuous changes in the genetic diversity of co-circulating noroviruses and the emergence of new recombinant variants are observed worldwide. Recently, new recombinant noroviruses with a novel GII.P16 polymerase associated with different capsid proteins VP1 were reported. As a part of the surveillance study of sporadic cases of acute gastroenteritis in Novosibirsk, a total of 46 clinical samples from children with diarrhea were screened in 2016. Norovirus was detected in six samples from hospitalized children by RT-PCR. The identified noroviruses were classified as recombinant variants GII.P21/GII.3, GII.Pe/GII.4_Sydney_2012, and GII.P16/GII.4_Sydney_2012 by sequencing of the ORF1/ORF2 junction. In Novosibirsk, the first appearance of the new recombinant genotype GII.P16/GII.4_Sydney_2012 was recorded in spring 2016. Before this study, only four complete genome sequences of the Russian GII.P16/GII.3 norovirus strains were available in the GenBank database. In this work, the complete genome sequence of the Russian strain Hu/GII.P16-GII.4/RUS/Novosibirsk/NS16-C38/2016 (GenBank KY210980) was determined. A comparison of the nucleotide and the deduced amino acid sequences showed a high homology of the Russian strain with GII.P16/GII.4_Sydney_2012 strains from other parts of the world. A comparative analysis showed that several unique substitutions occurred in the GII.P16 polymerase, N-terminal p48 protein, and minor capsid protein VP2 genes, while no unique changes in the capsid VP1 gene were observed. A functional significance of these changes suggests that a wide distribution of the strains with the novel GII.P16 polymerase may be associated both with several amino acid substitutions in the polymerase active center and with the insertion of glutamic acid or glycine in an N-terminal p48 protein that blocks the secretory immunity of intestinal epithelial cells. Further monitoring of genotypes will allow determining the distribution of norovirus recombinants with the polymerase GII.P16 in Russia

Epizootic Situation on Anaplasmosis of Small Ruminants in the Irkutsk Region

Anaplasmosis of ruminants is a group of natural focal infections caused by bacteria from the genus Anaplasma of the Anaplasmataceae family. The main etiological agent of anaplasmosis in sheep, goats, and wild ruminants is Anaplasma ovis, which parasitizes in the erythrocytes of these animals. The purpose of this study was the finding and identification of Anaplasma spp. in the blood of small ruminants using genetic methods and obtaining data on the distribution of anaplasmosis in the Irkutsk region. 20 goat blood samples, 611 sheep blood samples and 209 Dermacentor nuttalli ticks from 12 districts of the Irkutsk region were examined for the presence of Anaplasma spp. Only one type of anaplasma, A. ovis, was found among the genotyped samples. A. ovis was found in the blood of sheep and goats in all of the studied districts of the Irkutsk region. The proportion of sheep blood samples containing anaplasma DNA varied from 30 % to 85 %, in goats – from 10 % to 100 % in different districts, and averaged 57.8 % in sheep and 55,0 % in goats. Frequency of infection of D. nuttalli ticks with A. ovis was 5.7 %. The nucleotide sequences of the samples detected in the blood of small ruminants on the territory of the Irkutsk region differed from each other by a single nucleotide substitution and were identical to the sequences of the type strain Haibei, as well as the sequences of A. ovis previously found in the blood of sheep from Mongolia, deer from China, and Dermacentor niveus and Dermacentor nuttalli ticks from China. These sequences were also identical to the sequences previously found in the blood of sheep from Altai and in Dermacentor nuttalli ticks from Tuva, which indicates the wide distribution of these A. ovis genovariants in Siberia and the probable role of D. nuttalli as a carrier of the agent of anaplasmosis of small ruminants in the Irkutsk region
