The paper highlights new data on the species composition of gamasid ticks living in the nests of the common vole of the Prisevan meso-foci of the Transcaucasian high-mountain natural plague foci of the Republic of Armenia. As a result of the research conducted in the studied territory, the fauna of gamasid ticks is represented by nine species, including two species that were not previously found in the nests of the common vole.

The article analyzes the biological diversity of the fauna of the ticks of the Republic of Abkhazia. Their biotopic confinement and parasite-host bonds at different stages of ontogenesis are considered. According to the materials of the authors ' collections, literary sources and partially the collections of the FKUZ Stavropol antiplague institute of Rospotrebnadzor for the territory of Abkhazia, data on 14 ticks species are given. Comparatively low species diversity is due to insufficient study of the ticks of Abkhazia.

The studies described in the article were conducted from 2018 to 2022 on the territory of 7 subjects of the North Caucasus Federal District of the Russian Federation. When collecting epidemiological data on human cystic echinococcosis, statistical data from the reference center for monitoring larval helminthiasis, operating on the basis of the Federal State Budgetary Institution "Rostov Research Institute of Microbiology and Parasitology" of Rospotrebnadzor, the departments of Rospotrebnadzor by subjects, the Federal State Budgetary Institution in the subjects of the Russian Federation and the results of their own research, were used. Thus, 234 cases of human echinococcosis of various localization were registered in the region. In all cases, the diagnosis was confirmed by laboratory method. No deaths have been reported.

The article presents data on the prevalence of echinococcosis in Central Asia over the past few years. The work used the results of epidemiological statistics, documents and reports of comparative data on the incidence of echinococcosis, registered in Central Asia. In recent years, there has been an increase in the incidence of echinococcosis in developed countries, and cases of infection in European cities have begun to be recorded.

The paper presents data on helminthozoonoses of fish of southern Sakhalin, according to the results of studies in 2000-2023. Based on theoretical and empirical research, it is proposed to exclude plerocercodes from the list of parasites dangerous to humans. Trematodes of the genus Liliatrema are considered conditionally pathogenic, the statement requires experimental confirmation.

Based on studies (2016-2022) of diphyllobothriasis infestation of animals in the territory of the Commander Islands National Park, it was revealed that the average extent of Bering Arctic Fox invasion was 37.3%, with seasonal fluctuations: winter – 42.7%, spring – 36.6%, summer – 34.9% (fecal helminthoscopy, n=351). The American mink is infected with diphyllobothriids with an invasion intensity of 26.5%. Helminthological autopsies (n=11) revealed strobils of Diphyllobothrium spp. 5-15 specimens, 20-70 cm long, in 5 Bering Arctic foxes. At the autopsy of 10 individuals of the American mink and 1 individual of the Mednovsky Arctic fox, no diphyllobothriids were found, as well as during helminthoscopic examination of the feces of the Mednovsky Arctic fox (n=37). Encapsulated plerocercoids were detected in the spawning individuals of Oncorhynchus gorbusha

A retrospective epidemiological analysis of the incidence of natural focal zoonotic infections among the human population in the Krasnoyarsk Kray showed that the increase in the incidence of ixodid tick-borne borreliosis in 2022 could be caused by an increase in the number of people with post-acute COVID-19 syndrome, who probably have dysregulation of the immune response and increased sensitivity to various pathogens.

There were no significant gender differences in infectious sensitivity to Borrelia in people who underwent COVID-19. At the same time, among people diagnosed with borreliosis, the proportion of women who have previously had COVID-19 is increased. The same happens with tick-borne encephalitis: a higher infectious sensitivity of women to the encephalitis virus is a statistically justified fact in people who have undergone COVID-19.

Nowadays one of the most important medical and social problems of morbidity is intensive parasitic pollution of the environment and the associated incidence of parasitic diseases. Human helminth infections continue to be the most important problem in the society. This is due to their widespread distribution in the world including the Russian Federation.

Purpose of the study: to determine the sanitary condition of the soil, wastewater and sediments, as well as the degree of epidemic danger in the city of Nizhnevartovsk and the Nizhnevartovsk region.

The article is devoted to the description of the formation, goals and objectives of medical archaeoparasitology, the research methods used by it, the relationship with other sciences of this field, the importance of its results for understanding the evolution of parasitic diseases under the influence of population migration, host change, and climate change.

Common symbol of medicine is the snake entwining the stick or “the staff of Asclepius”. This image is presented on the emblem (coat of arms) and flag of the World Health Organization.

The authors explain the image of the snake entwining the stick as a reflection of the ancient method of extraction of guinea worm.

Based on a critical analysis of literary data and our own experience in teaching medical terminology to Russian (Russian-speaking) students, the work presents the features of terminology that determine the basic principles of linguodidactics of this discipline and the success of its mastery. Using the identified features as an example, methodological approaches to describing cognitive processes in the formation of clinical thinking of a future doctor are assessed. The hypothesis about the hierarchical structure of linguistic knowledge and clinical thinking is discussed. It is concluded that it is necessary to integrate scientific data from neurobiological sciences at the present stage of development of didactics in the formation of clinical thinking.
