Akhal-Teke is the ancient cultural horse breed of oriental origin. The study of genetic features different subpopulations of Akhal-Teke breed was carried out on 17 loci of DNA microsatellites (VHL20, HTG4, AHT4, HMS7, HTG6, AHT5, HMS6, ASB23, ASB2, HTG10, HTG7, HMS3, HMS2, ASB17, LEX3, HMS1 and CA425) to assess their genetic differentiation. The results of DNA typing of 5457 Akhal-Teke horses on 17 microsatellite loci show that gene pool of world population is represented by 121 alleles, among which 98 are found in all countries. Comparative analysis of genotypes of horses representing different subpopulations indicates that they differ in the number of alleles (100-117), allele frequencies, the level of polymorphism Ae (3.40-3.91) and the degree of observed heterozygosity Ho (0.661-0.724). The genetic distances between the subpopulations varied in range from 0.007 (Russia – CIS) to 0.051 (Czechia – Turkmenistan). Correspondence to HWE was maintained in all countries, which confirms the negative value Fis. Genetic options of the Akhal-Teke by index Fst varied in a range 0.001 -0.078 at the mean value Fst=0.022. Cluster analysis demonstrated more close relationship between Russian, CIS and European subpopulations.

New data about pathogenicity of Rickettsia sibirica subspecies BJ-90 were obtained. Rickettsial strains of this subspecies from the Primorye region were pathogenic for guinea pigs and chick embryos, multiplied in cell cultures Vero E6. Antibodies against Rickettsia sibirica subspecies BJ-90 in ELISA were detected in the Omsk region in patients with clinical manifestations after bites of ticks. Analysis of available data indicates to the likely pathogenicity of this genotype for human. Due to the low cross reactivity of R. sibirica subsp. BJ-90 and R. sibirica subsp. sibirica in combined foci serological diagnosis of tick-borne rickettsioses in ELISA should be carried out with antigens of both subspecies of Rickettsia sibirica.

Objective is to analyze the incidence of Siberian tick typhus (STT) in the Russian Federation over the period of 2010–2020, Astrakhan spotted fever (ASF) and Mediterranean fever (MF) since the official registration, and to forecast the development of the epidemic process for endemic rickettsioses for 2021. The analysis of the incidence of STT, ASF and MF in Russia for the period of 2010–2020, 2013–2020 and 2014–2020, respectively, has been carried out. The forecast of endemic rickettsioses morbidity in the European and Asian parts of Russia for 2021 has been made. The average long-term incidence of STT for 2010–2020 in the Russian Federation as a whole was 1.04 (CI95 1.02÷1.05) 0/0000, with no tendency to change. The maximum relative incidence of STT is typical for the Siberian Federal District (SFD), where the average long-term incidence rate for 2010–2020 was 6.20 (CI95 6.08÷6.31) per 100 thousand of the population. The Far Eastern Federal District (FEFD) – 4.70 (CI95 4.53÷4.87) 0/0000 came in second place, the third place was taken by the Ural Federal District (UFD) – 0.08 (CI95 0.07÷0.10) 0/0000. When assessing the 11-year dynamics of the relative incidence of STT by the Federal Districts, we have detected a tendency to its stabilization in the SFD and the FEFD. In the UFD, a significant downward trend was revealed. The upward trend in the incidence of STT remained in the Altai Republic. Major decline in STT incidence was observed in the Kurgan Region, Trans-Baikal Territory, Krasnoyarsk Territory, and the Republic of Khakassia. There was a declining trend in the incidence of Astrakhan spotted fever in the Astrakhan Region and the Republic of Kalmykia. In the Republic of Crimea and the city of Sevastopol there is no trend to increase the incidence of Mediterranean fever.

Статья посвящена опыту организации элективного курса в контексте двуязычного обучения. В статье представлено исследование англоязычной и немецкоязычной прессы в авторском элективном курсе, в основе которого лежит изучение иноязычных неологизмов. Авторы приходят к выводу, что понимание вопроса изучения двух иностранных языков одновременно в современных образовательных реалиях формирует условия для активизации уровня владения иностранными языками. Особое внимание уделено возрастающей роли иностранного языка для современного профессионала. Поэтому двуязычное (билингвальное) обучение английскому и немецкому языкам одновременно приобретает особое значение. Авторы подробно рассматривают и доказывают необходимость внедрения элективных курсов по иностранным языкам в вузовское образование. В статье анализируются неологизмы с усиленной информирующей функцией на материале немецкого и английского языков. Обосновывается идея о том, что владение неологизмами в области политики, государственного устройства, социальной сферы имеет ключевое значение для будущего профессионала. Выделяются и описываются характерные особенности задач и приемов обучения, использованные при обучении на данном элективном курсе. В статье обобщается практический опыт изучения неологизмов, анализируется структура новых лексических единиц в немецком и английском языках.
