The article discusses some characteristics of the ecology of the tick Ixodes ricinus, which is often found in the central part of Eastern Europe and in many regions of the Russian Federation including the Kursk Region. Some circulation patterns of tick-borne borreliosis in natural foci of the Kursk Region and cases of infected humans are shown. The main material was the data from the state reports of the Federal Service for Supervision of Consumer Rights Protection and Human WellBeing for 2015–2021. A comparative analysis was conducted of the number of cases infected with ixodid tick-borne borreliosis (ITBB) with the I. ricinus infection rate in natural foci in the Kursk Region from 2015 to 2021. The ITBB circulation is widespread throughout the Kursk Region. According to our observations, the peaks of infection of humans with ITBB may depend on the circulation characteristics of Borrelia among I. ricinus and their feeders. In the results of the study, it can be noted that the I. ricinus population has a temporary downward trend, while the percentage of infected ticks fluctuates slightly and has a cyclic nature. The number of cases of people presenting tick bites is interrelated with the population density and the nature of ixodid ticks spreading in the Kursk Region.

The American mink is an introduced species for the Kirov Region. The analysis of helminth infection of the American mink was carried out in urban conditions and natural biocenoses of the Kirov Region (floodplains of the Vyatka, Kama, Cheptsa and Moloma Rivers) in the north-east of the European part of Russia. The method of complete helminthological dissection was used to study 109 carcasses of the American mink from natural biocenoses and urbanized landscapes of the city of Kirov and other settlements of the Kirov Region (residential areas). In the studied animals, species, sex, age, weight and fatness of the animal were determined. Age was determined by the method of V. G. Klevezal. Eighteen species of parasitic worms belonging to 3 classes were identified, namely, trematodes (4 species), nematodes (13 species), and cestodes (1 species). Five new species were found for the Kirov Region including Metorchis bilis (Braun, 1890), Crenosoma taiga (Skrjabin et Petrov, 1928), and Mustelivingylus skrjabini (Romanov et Kontrimavichus, 1962). Of these, 8 species were found in urban areas. Most often, infection occurred with 4 helminth species, Aonchotheca putorii, Aonchotheca mucronata, Crenosoma taiga, and Skrjabingylus nasicola. Epizootological and epidemiological danger is posed by Trichinella nativa. In minks, the bladder (A. mucronata) and frontal sinuses (Sk. nasicola) are often affected.
美洲水貂是基洛夫地区引进的物种。在俄罗斯欧洲部分东北部基洛夫地区(维亚特卡河、卡马河、切普察河和莫洛马河泛滥平原)的城市条件和自然生物环境中对美洲水貂的寄生虫感染进行了分析。采用寄生虫学完全解剖的方法，对基洛夫市自然生态环境、城市化景观和基洛夫地区其他居民点(居民区)的109具美洲水貂尸体进行了研究。对所研究动物的种类、性别、年龄、体重和脂肪进行了测定。采用V. G. Klevezal法测定年龄。共鉴定出吸虫(4种)、线虫(13种)、囊虫(1种)3纲18种寄生虫。在基洛夫地区发现了5个新种，包括Metorchis bilis (Braun, 1890)、Crenosoma taiga (Skrjabin et Petrov, 1928)和Mustelivingylus skrjabini (Romanov et Kontrimavichus, 1962)。其中8种分布于市区。最常发生感染的寄生虫有4种，分别是putoriaonchotheca、mucronata Aonchotheca、Crenosoma taiga和Skrjabingylus nasicola。本地旋毛虫构成了流行病学和流行病学危险。在水貂中，膀胱(A. mucronata)和额窦(Sk. nasicola)经常受到影响。

Wild carnivores are involved in the maintenance of natural foci of helminth infections, and among their pathogens there are species of zoonotic significance. The purpose of the research was the study of helminth distribution in the fox (Vulpes vulpes) in the Central Region of the European part of Russia. Thirty foxes were examined by the method of complete helminthological dissections. Twenty three helminth species were recorded including the following 17 species in the digestive tract: Aonchotheca putorii (23.3%), Gnathostoma spinigerum (3.3%), Uncinaria stenocephala (66.6%), Toxascaris leonina (53.3%), Toxocara canis (23.3%), Molineus patens (13.3%), Ancylostoma caninum (3.3%), Taenia sp. (40%), Echinococcus multilocularis (30.0%), Mesocestoides sp. (10.0%), Macracanthorhynchus catulinus (13.3%), Alaria alata (66.6%), Apophallus donicus (50.0%), Isthmiophora melis (23.3%), Metorchis bilis (23.3%), Opisthorchis felineus (13.3%), and Echinochasmus perfoliatus (6.6%). The following three nematode species were found in the respiratory system: Eucoleus boehmi (26.6%), Eucoleus aerophilus (63.3%), and Crenosoma vulpis (46.6%). The nematode Dirofilaria immitis (3.3%) was found in the heart of one fox. Half of the animals had Pearsonema plica (syn. Capillaria plica) (50%) in the bladder. Trichinella sp. (6.6%) were found in the muscle tissue. We identified 6 nematode species, 1 cestode species and 5 trematode species which are pathogens of zoonosis.

The article considers the transformation of the helminth fauna in the alpine hare over the 40s of the last century to the present day. The method of complete and partial helminthological dissections was used to study helminths in 55 alpine hares. For the entire period of research, 11 species of parasitic worms were recorded in the alpine hare in the Kirov Region. We found 6 helminth species, namely, 2 cestode species, Taenia macrocystis and Mozgovoyia pectinata, and 4 nematode species, Protostrongylus terminalis, P. kamenskyi, Trichostrongylus retortaeformis, and Graphidium strigosum. At the moment, there are no 5 helminth species in the alpine hare. According to the survey data and our research, Taenia pisiformis (larvae) has not been recorded in the alpine hare since the 70s of the last century; the definitive host, the lynx, does not have it. This cestode was supplanted by Taenia macrocystis. Taenia pisiformis (larvae) occurs only in synanthropic foci in rabbits and dogs. We recorded the cestode Multiceps serialis (larvae) neither in hares, nor in the final hosts, predatory mammals. We did not detect the trematode Fasciola hepatica. Our studies have shown that helminths of the alpine hare in the Kirov Region remain incompletely studied due to the transformed biocenoses; new species are introduced and the previously identified species disappear.

The purpose of the research is to study the features of the mechanochemical modification of medicinal substances with low solubility in water. According to the Biopharmaceutics Classification System, about 6% of medicinal substances belong to the group of insoluble medicinal substances, and about 47%, to practically insoluble medicinal substances, i.e. more than a half substances have problems with solubility, and therefore bioavailability and pharmacological activity. To achieve the therapeutic effect of such substances, it is necessary to deliberately increase the dosage of the substance, which increases the cost of the drug, as well as safety risks of pharmacotherapy. The work evaluated possibilities of mechanochemical modification of a number of known anthelmintic substances with low solubility to increase this parameter. It was shown that during machining of such substances in the presence of polymeric substances, solid dispersions were formed that had increased solubility while maintaining high anthelmintic activity with decreased dosage of the active substance. Preparations in the form of solid dispersions can be used both orally and by a group method to 10-20 animals, mixed with compound feed. For low-melting substances, a liquid-phase machining method is proposed to obtain stable suspension concentrates that are convenient for oral administration. The prospects for obtaining mixed compositions based on two substances are shown, which makes it possible to obtain combined preparations with a wide spectrum of action with the minimized volume and frequency of their use.

The importance of wetlands for humanity is very high. They provide a huge number of people in the world with their water and biological resources, determine the stability of local climatic conditions, and serve as habitats for many sedentary and migratory waterfowl and semiaquatic birds. In the reservoirs of the transboundary rivers Amudarya, Syrdarya and Zarafshan (within Uzbekistan), numerous species of wetland birds are concentrated, which are poorly studied in terms of parasitology. The paper presents some features of the helminth fauna in wetland birds of NorthWestern, Central and North-Eastern Uzbekistan. The material for this work was the collection of parasitic worms of waterfowl, marsh and semiaquatic birds caught in the water bodies of the Amudarya, Syrdarya and Zarafshan river basins (within Uzbekistan) during the hunting season (2018–2022). More than 750 birds belonging to 40 species, 26 genera, 15 families and 9 orders were collected and studied. The studied birds turned out to be infected with helminths of 4 classes, Cestoda, Trematoda, Acanthocephala and Nematoda. One hundred seventeen species were identified: 29 species belonged to the cestode class, the trematode class was represented by 67 species, the nematode class, by 27 species, and the acanthocephalan class by 4 species. Original data on the structure of the helminth fauna of 9 orders of birds were presented. Various transmission ways of helminths to the final hosts were elucidated.

This paper presents the results of a study of the muscular system of the trematode D. lanceatum, the causative agent of dicrocoeliosis, a widespread parasitic disease of the grass-feeding ruminants. As a result of the used fluorophore-conjugated phalloidin, data were obtained on the organized muscles of the body wall, attachment organs, and digestive, reproductive and excretory systems of D. lanceatum. The body wall musculature is represented by three layers of muscle fibers: circular, longitudinal and diagonal. The character of the muscle fiber location is different in the anterior, middle and posterior parts of the body. The paper describes several types of muscle fibers found in the oral and ventral suckers, and digestive, reproductive and excretory systems of the parasite. An analysis of the data obtained and available in the literature showed the presence, along with common features, of differences in the organization of the muscular system of various trematode species. The results obtained expand and deepen the understanding of the trematode morphology, the organization of their muscular system, and make it possible to detect similar and different features in the structure of the muscular system of organs and tissues of species of various taxonomic groups of trematodes.

The evolution of flowering plants including the Gramineae family is associated with birds and mammals that play a large role in distribution of seeds. The appearance of galls in the evolution which are formed as a result of the vital activity of Anguina in various organs of cereal plants resembles the convergence process with flowering plant seeds. Like seeds, galls firstly appear to be the resting structures having a strong envelope which helps Anguina to survive unfavorable conditions. Like seeds, galls possess the same distribution ways that have been developed in the evolution, namely by wind, water, mammals and birds. Anguina form galls that look like seeds of cereals, namely plant embryo in a seed and many nematodes in galls. Together with coevolution of the epiphytosystem (plant + phytoparasite + herbivore), one herbivore species in biogeocenosis is changed for another species that ousts it in the competitive struggle. However due to its peculiarities such species spread seeds and galls poorly. Different microorganisms adapt to each species of the epiphytosystem including those "useful" for the epiphytosystem. Bacteria Rathayibacter tritici and R. toxicus colonized galls and caused death of herbivorous mammals. Those animals stopped to consume cereal seeds and galls which granivorous birds began to consume and "sow" seeds and galls into typical and other biogeocenoses. As a result of the coevolution, the epiphytosystem with included toxic microorganisms developed to a higher level. The very set of anguinosis epiphytosystems in a particular biogeocenosis is determined by historically established interspecific relationships and characteristics of coalition of host plants, Anguina, “useful” bacteria, herbivores and birds.

Preparative immunological and serological studies for toxoplasmosis and toxocariasis were carried out. Antigenic and antibody immunoreagents based on proliferative forms of Toxoplasma gondii, excretory and secretory components of larval stages of Toxocara canis and specific immune sera were developed. When using the obtained diagnostic preparations, the blood serum of livestock and carnivorous animals and humans was examined for Toxoplasma and Toxocara antibodies and antigens using the immunochromatographic assay (IСA). IgG to Toxoplasma gondii in an ELISA were found in young men under 17 years of age. A study using the ICA express test of blood serum of housewives and students from the Northwest African countries revealed Toxoplasma antigens in 1.2 and 9.0%, respectively, and antibodies in 10.5 and 16.0%. The ICA in different age groups of people showed the highest level of Toxocara canis seropositivity among children, adolescents and young people aged from 9–12 to 17–20 years. Immunochromatographic assay belongs to the group of molecular biological methods and allows reliable detection, in the express test variant, of both pathogen antigens and antibodies. The ICA informativeness is 98% with high sensitivity. The above method in the express test variant makes it possible to seroepidemiological and seroepizootological monitoring for acute and latent toxoplasmosis, as well as for toxocariasis (larva migrans syndrome).
