    The purpose of the research is evaluating the efficacy of complex therapy using dironet, lactobifadol and keratin food supplement (DLK) against toxascariosis of the arctic fox.Materials and methods. To determine the helminth fauna in the conditions of Vyatka Fur Breeding Farm, 61 females silver fox and 55 females voilevoy arctic fox were used as study objects. To conduct complex therapy against toxascariosis, the study object was 24 females culled from the breeding herd, spontaneously infected with toxascariosis and being clinically healthy. The morphological and biochemical blood parameters in female foxes were determined before and after dehelminthization, and control weighing of animals from experimental groups was carried out before and after the experiment.Results and discussion. Of the studied 116 fur-bearing animals, 26 (22.4%) were infected with Toxascaris leonina. Infection rate of Toxascaris sp. in silver fox females aged 5–7 years was 42.6% when 7-9 eggs were found in one microscope field (magnification 7 Γ— 9). Infection with Toxascaris sp. affects on the body weight of infected animals. The females silver fox from the second experimental group infected with Toxascaris sp., which were not treated, had an average live weight of 1.3 kg less (16.6%) as compared to the control. The complex therapy with the DLK treatment-and-prophylactic complex contributed to the improved metabolic processes and digestion. The applicability of the DLK treatment-and-prophylactic complex for therapy against toxascariosis was proved

    The purpose of the research is determining the effect of the therapeutic and prophylactic complex of Dironet, Lactobifadol and fodder Keratin (DLK) on the qualitative and quantitative composition of the intestinal microflora affected by toxascariosis in the Blue Frost fox.Materials and methods. The research was carried out on the Fur Breeding Farm β€œVyatka”, Slobodskoy District, the Kirov Region. The study objects were 24 female Blue Frost foxes culled from the breeding herd. To determine the quality of the skins obtained from the experimental animals, we sorted flint-dried skins.Results and discussion. After the introduction of the therapeutic and preventive complex DLK into the diet of sick animals, the positive dynamics was observed in the quantitative and qualitative composition of intestinal microorganisms. In animals of the experimental groups that were administered DLK, the number of bifidus bacteria, lactic bacteria and fecal enterococci increased; there was a significant decrease or complete absence of pathogenic and conditionally pathogenic microorganisms, fusobacteria, streptococci, clostridia, typical lactose-negative and hemolytic Escherichia, aureus and saprophytic staphylococcus, common Proteus and fungi of the Candida genus. In animals infected by Toxascaris leonina that did not receive the complex therapy, a decrease in lactic acid bacteria and an increase in the content of pathogenic and commensal microorganisms were noted. Under the output of the fur production, the infected animals showed the lowest percentage of skins in terms of quality of 7.16%, which was 0.38% less in comparison with healthy foxes, and 0.51% less in comparison with treated Blue Frost foxes

    The purpose of the research is a regression mathematical modeling of the population of small mammals, hosts of ixodid ticks in the Kaluga Region, which allows assessing the likelihood of zoonotic and vector-borne diseases.Materials and methods. For 10 years (from 2009 to 2019), a 2k multifactorial experiment was performed in the field by the method of V. V. Kalmykov (2016). The study object was mouse-like rodents that are the most common in the Kaluga Region. Rodents were counted by standard methods using techniques of V. N. Shnitnikov (1929), P. B. Yurgenson (1934) and A. N. Formozov (1937). The generally accepted steel spring traps were used. Animals were counted throughout all habitats.Results and discussion. Regression mathematical models of the mouse-like rodent population were obtained depending on the average monthly temperature, precipitation and atmospheric pressure for the year in the Non-Black Earth Zone by the example of the Kaluga Region. The specific nature of the obtained analytical model is that the greatest influence on the population of small mammals is made by the interaction effect of two factors, temperature and atmospheric pressure. Their impact is more significant than the influence of each of the three study factors separately, in particular, it is stronger than the only influence of temperature by 1.02, the only impact of precipitation by 2.58, and the only impact of atmospheric pressure by 2.72. The analytic mathematical model allows us to calculate, without significant material or time costs, populations of mouse-like rodents not only in the Kaluga Region, but also in regions with similar climate conditions

    The purpose of the research is finding out features of fauna and ecology of ixodid ticks parasitizing in the Non-Black Earth Region of the central part of the East European Plain, which inhabit the Kaluga Region. Materials and methods. Ixodid ticks were collected and recorded according to generally accepted methods in all districts of the Kaluga Region and the city of Kaluga in 2009–2019 during their activity (in the spring from the melting of snow and until late autumn before the snow cover formation). A total of 11,282 ticks were collected in 412 flag-hours, of which 7,421 (65.7%) were collected from vegetation and 3,861 (34.3%) from animals. We studied open meadow and field areas, forest and shrub areas, closed meadow and field areas, and wetland stations and settlements. The species was identified using the Atlas of ixodid ticks by Ganiev and Aliverdiev (1968) and the Atlas by Shevkoplyas (2008). Results and discussion. There are two species of ixodid ticks in the Kaluga Region, Ixodes ricinus and DermacentΠΎr reticulatus. The number of D. reticulatus slightly exceeds (by 6%) I. ricinus, 53 and 46% respectively, which is explained by the even distribution of forest and meadow (pasture) biotopes in the Region. The abundance index of I. ricinus was 16.8Β±1.32 individuals per 1 flag-hour in forest biotopes, and 11.6Β±1.12 individuals per 1 flag-hour in meadow biotopes. The abundance index of D. reticulatus was 10.8Β±1.14 individuals per 1 flag-hour in forest biotopes, and 15.9Β±1.30 individuals per 1 flag-hour in meadow biotopes.ЦСль исслСдований – Π²Ρ‹ΡΡΠ½ΠΈΡ‚ΡŒ Ρ„Π°ΡƒΠ½ΠΎ-экологичСскиС особСнности паразитирования иксодовых ΠΊΠ»Π΅Ρ‰Π΅ΠΉ, ΠΎΠ±ΠΈΡ‚Π°ΡŽΡ‰ΠΈΡ… Π² НСчСрнозСмной Π·ΠΎΠ½Π΅ Π¦Π΅Π½Ρ‚Ρ€Π°Π»ΡŒΠ½ΠΎΠΉ части Восточно-ЕвропСйской Ρ€Π°Π²Π½ΠΈΠ½Ρ‹.

    the purpose of the research is monitoring population and species composition of common blood-sucking ectoparasites of the Kaluga Region, mosquitoes and ixodid ticks, and parasitic zoonoses, in the circulation of which they are involved.Materials and methods. The records were made in all districts of the Kaluga Region and in the city of Kaluga. We studied open meadow-field and forest-shrub stations, closed meadow-field and near-water stations, and settlement stations. The species was identified using the atlases of ixodid ticks by I. M. Ganiev, A. A. Aliverdiev (1968) and V. N. Shevkoplyas (2008), and the guidance of R. M. Gornostaeva (1999). The situation with transmissible parasitic zoonoses in the Kaluga Region was assessed based on the analysis of information from open sources of the Hygienic and Epidemiological Center of the Kaluga Region and the Veterinary Committee under the Government of the Kaluga Region.Results and discussion. There are two species of ixodid ticks in the Kaluga region: Ixodes ricinus and Dermacentor reticulatus. The abundance index of ixodid ticks of the species I. ricinus is 16.8Β±1.32 individuals per 1 flag-hour in forest biotopes, and 11.6Β±1.12 individuals per 1 flag-hour in meadow biotopes, and the abundance index of D. reticulatus is 10,8Β±1.14 and 15.9Β±1.30 individuals per 1 flag-hour, respectively. Three mosquito species prevail, namely, Stegomya communis, S. vexans, and Culex pipiens. The maximum number was 8 thousand per 1 m3. During the study period, the causative agent of infectious tick-borne borreliosis was found on average in 10.6% of ixodid ticks collected from humans and in 13.2% of ticks collected in natural biotopes. The causative agent of human granulocytic anaplasmosis was isolated on average in 3.1% of ixodid ticks collected from humans and 6.4% of those collected in natural biotopes. Infection rate for I. ricinus ticks infected with pathogen of infectious tick-borne borreliosis was 16.9%, and D. reticulatus 12.3%.ЦСль исслСдований: провСсти ΠΌΠΎΠ½ΠΈΡ‚ΠΎΡ€ΠΈΠ½Π³ числСнности, Π²ΠΈΠ΄ΠΎΠ²ΠΎΠ³ΠΎ состава распространСнных кровососущих эктопаразитов ΠšΠ°Π»ΡƒΠΆΡΠΊΠΎΠΉ области – ΠΊΠΎΠΌΠ°Ρ€ΠΎΠ² ΠΈ иксодовых ΠΊΠ»Π΅Ρ‰Π΅ΠΉ ΠΈ ΠΏΠ°Ρ€Π°Π·ΠΈΡ‚Π°Ρ€Π½Ρ‹Ρ… Π·ΠΎΠΎΠ½ΠΎΠ·ΠΎΠ², Π² циркуляции ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Ρ… ΠΎΠ½ΠΈ ΡƒΡ‡Π°ΡΡ‚Π²ΡƒΡŽΡ‚.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is to study and systematize data on the biological, fauna-ecological characteristics of mosquitoes Culex pipiens Culex Linnaeus species in the Kaluga Region.Materials and methods. To clarify the fauna and ecological characteristics of mosquitoes Culex pipiens Culex Linnaeus species in the Kaluga Region, we caught adults, larvae and pupae of mosquitoes in the basements of the city of Kaluga, on the control day of mosquitoes, in the natural land biotopes of the Kaluga region. The larvae of blood-sucking mosquitoes were observed on natural and artificial reservoirs of the city and region, in puddles, trenches. Mosquitoes were caught during an attack on a person or animal with an entomological net and placed in a specially prepared cage. Larvae and pupae were collected at breeding sites (from aquatic plants, in the water column). The study of the biotopic distribution and daily activity was carried out using the method of accounting for the number of insects attacking the human forearm for 20 minutes in the period from 20:00–24:00 h.Results and discussion. Two forms of mosquitoes Culex pipiens Culex Linnaeus, 1758 (Diptera, Culicidae) are found in the Kaluga Region: Cx. pipiens f. pipiens L. (non-autogenous form) and Cx. p. f. molestus fors. (autogenous form). Form Cx. pipiens f. pipiens L. is very aggressive, lives in urban and agricultural areas. Cx p. f. molestus fors. is an urbanized form; prefers to live and develop in urban environments. A feature is also the possibility of the first laying of eggs without bloodsucking, and the larvae can develop without sunlight. In late August, female C. pipiens mosquitoes can enter diapause before spring. A temperature below 4Β°C and above 35Β°C is critical for the development of larvae. In a year, 3–4 mosquito generations develop in the Kaluga Region. ЦСль исслСдований: ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ ΠΈ ΡΠΈΡΡ‚Π΅ΠΌΠ°Ρ‚ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Ρ‚ΡŒ Π΄Π°Π½Π½Ρ‹Π΅ ΠΎ биологичСских, Ρ„Π°ΡƒΠ½ΠΎ-экологичСских особСнностях ΠΊΠΎΠΌΠ°Ρ€ΠΎΠ² Π²ΠΈΠ΄Π° Culex pipiens Culex Linnaeus Π² ΠšΠ°Π»ΡƒΠΆΡΠΊΠΎΠΉ области.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is development of preventive measures against zooanthroponoze vector-borne diseases spread by parasitic arthropods in the Kaluga Region.Materials and methods. The subject of the research was Ixodidae, mosquitoes, and small mammals inhabiting the Kaluga Region. The census of parasitic arthropods was carried out on the territory of all districts of the Kaluga Region and the city of Kaluga. Open natural habitat and human settlements were investigated. Weather conditions from 2013 to 2018 were also taken into account. For the purposes of the study, we used standard methods for capturing and counting arthropods and mouse-like rodents. In order to obtain mathematical models of small mammal populations, a full factorial experiment was conducted using the collected statistical data. In-process testing of the drug based on s-fenvalerate and piperonyl butoxide were carried out under the conditions of the agricultural collective farm β€œNiva” of the Kozelsky District, the Kaluga Region, and LLC β€œAngus Center of Genetics” of the Babyninsky District, the Kaluga Region.Results and discussion. In the Kaluga Region, two species of ixodic ticks are found, namely, Ixodes ricinus and Dermacentor reticulatus, which have two activity peaks. Mosquito may have 3-4 generations in a year in the Kaluga region. The most common mosquito species in the Kaluga Region are Aedes communis, Ae. (Och.) togoi and Ae. (Och.) diantaeus, Culex pipiens Culex Linnaeus, 1758 (Diptera, Culicidae) (Culex pipiens): Cx. pipiens f. pipiens L. (non-autogenic form) and Cx. p. f. molestus Fors. (autogenic form), which interbreed, and reproductively isolated in the Region. The developed mathematical models make it possible to quantify the risks of outbreaks of zooanthroponoze vector-borne diseases without the cost of field research, and allow for rational, timely and effective preventive measures. Medications based on s-fenvalerate and piperonyl butoxide and based on cyfluthrin showed high insecto-acaricidal efficacy and safety.ЦСль исслСдований: Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠ° профилактичСских ΠΌΠ΅Ρ€ ΠΏΡ€ΠΎΡ‚ΠΈΠ² Π·ΠΎΠΎΠ°Π½Ρ‚Ρ€ΠΎΠΏΠΎΠ½ΠΎΠ·Π½Ρ‹Ρ… трансмиссивных Π±ΠΎΠ»Π΅Π·Π½Π΅ΠΉ, распространяСмых паразитичСскими члСнистоногими Π½Π° Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ ΠšΠ°Π»ΡƒΠΆΡΠΊΠΎΠΉ области.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is studying the spread of endoparasites of sheep and goats in conditions of private farms. Materials and methods. The studies were carried out in December 2019 in the conditions of private farms in the Kaluga and Tver Regions. The study subjects were sheep and goats of various sex and age groups (adult females and males aged 2–3 years and young animals aged up to 6 months). The material was feces taken from the animals’ rectum. Total 45 samples of feces from sheep and goats from a private farm in the Kaluga Region and 30 samples from sheep from a farm in the Tver Region were collected and studied. Studies for helminth eggs in feces were carried out using the flotation nethod according to the Kotelnikov-Khrenov and the Shcherbovich-Shilnikov method to detect larvae at pulmonary nematodosis. Results and discussion. As a result of coproovoscopic research methods, we found that intestinal parasites in farm in the Kaluga Region were represented by three genera of nematodes - Trichostrongylus, Nematodirus and Capillaria, as well as Protozoa of the genus Eimeria. Eggs of nematodes from the genus Trichostrongylus and Protozoa from the genus Eimeria were found in feces of sheep from the farm in the Tver Region. The infection rate with intestinal parasites in sheep and goats from two farms were similar. Pathogens from the genus Trichostrongylus prevailed, which was obviously associated with similar conditions for keeping and feeding small cattle on both farms. According to the results of fecal studies, the dominant parasitosis in animals from both farms were gastrointestinal strongylatosis. ЦСль исслСдований: ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ распространСния эндопаразитов Ρƒ ΠΎΠ²Π΅Ρ† ΠΈ ΠΊΠΎΠ· Π² условиях частных Ρ„Π΅Ρ€ΠΌ.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is evaluating the efficacy of complex therapy using dironet, lactobifadol and keratin food supplement (DLK) against toxascariosis of the arctic fox.Materials and methods. To determine the helminth fauna in the conditions of Vyatka Fur Breeding Farm, 61 females silver fox and 55 females voilevoy arctic fox were used as study objects. To conduct complex therapy against toxascariosis, the study object was 24 females culled from the breeding herd, spontaneously infected with toxascariosis and being clinically healthy. The morphological and biochemical blood parameters in female foxes were determined before and after dehelminthization, and control weighing of animals from experimental groups was carried out before and after the experiment.Results and discussion. Of the studied 116 fur-bearing animals, 26 (22.4%) were infected with Toxascaris leonina. Infection rate of Toxascaris sp. in silver fox females aged 5–7 years was 42.6% when 7-9 eggs were found in one microscope field (magnification 7 Γ— 9). Infection with Toxascaris sp. affects on the body weight of infected animals. The females silver fox from the second experimental group infected with Toxascaris sp., which were not treated, had an average live weight of 1.3 kg less (16.6%) as compared to the control. The complex therapy with the DLK treatment-and-prophylactic complex contributed to the improved metabolic processes and digestion. The applicability of the DLK treatment-and-prophylactic complex for therapy against toxascariosis was proved.ЦСль исслСдований: ΠΎΡ†Π΅Π½ΠΊΠ° эффСктивности комплСксной Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ с использованиСм Π΄ΠΈΡ€ΠΎΠ½Π΅Ρ‚Π°, Π»Π°ΠΊΡ‚ΠΎΠ±ΠΈΡ„Π°Π΄ΠΎΠ»Π° ΠΈ ΠΊΠ΅Ρ€Π°Ρ‚ΠΈΠ½Π° ΠΊΠΎΡ€ΠΌΠΎΠ²ΠΎΠ³ΠΎ (Π”Π›Πš) ΠΏΡ€ΠΈ токсаскариозС пСсцов сСрСбристых.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
