    The purpose of the research is study of pinniped helminth fauna in Chukotka, and the analysis of the fish of the main commercial families infected with pathogens of helminthozoonoses based on modern literature.Materials and methods. The helminths were collected in autumn of 2019 from pinnipeds caught in the Mechigmenskaya Guba of the Bering Sea in the Chukotka Autonomous Okrug by the method of partial helminthological dissection per Skryabin (gastrointestinal tract). Samples were examined from 6 walruses and 26 seals (13 spotted seals and 13 ringed seals). The helminths found were fixed in 70% alcohol. The helminth species were identified at the Department of Parasitology and Veterinary and Sanitary Examination of the MVA named after K. I. Skryabin using reference literature.Results and discussion. All pinnipeds were infected with nematodes of the family Anisakidae. Mature Pseudoterranova desipiens were found in the walrus (Infection Prevalence = 16.7% with Infection Intensity = 3 specimens/animal), mature Ps. desipiens, as well as Contracoecum osculatum and Anisakis simplex larvae (IP = 30.8% with II from 5 to 57 specimens) were found in the spotted seal, and Ps. desipiens larvae and mature Ps. desipiens were found in the ringed seal (IP = 15.4% with II from 1 to 4 specimens). Thus, only Ps. desipiens were represented by mature stages (females and males), and two other species of anisakids, C. osculatum and A. simplex, were found in the seals in the larval stage

    Late Permian palynomorph assemblages from Ufimian and Kazanian type sequences in Russia, and comparison with Roadian and Wordian assemblages from the Canadian Arctic

    Tentative biostratigraphic correlations, based on marine faunas, have been made by various workers between Ufimian and Kazanian sequences in their type areas in the Volga-Urals region of Russia and Roadian and Wordian sequences in their type area in Texas, United States. Unfortunately, palynological correlation between the Russian and United States sequences is not possible, due to lack of data from the latter. However, detailed palynological data are available from rocks of Roadian and Wordian age in the Canadian Arctic Archipelago, and therefore indirect correlations are possible. Palynomorph assemblages from the Canadian Arctic and other circumpolar areas, such as the southern Barents Sea and Greenland, are different from those of the Ufimian and Kazanian Russian sequences in their type areas. This is likely to be the result of variations in the parent flora in response to significant paleoclimatic differences. For example, the climate of the Volga-Urals region in Late Permian times was probably hot and arid, whereas that of the Canadian Arctic, Barents Sea, and Greenland was cooler and probably more humid

    It is hard to make a conclusion about relationship between Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and Bronchoobstructive Syndrome (BOS) in the postcovid period based on the literature.The aim. To determine the optimal treatment approaches by conducting a comprehensive assessment of clinical, laboratory and functional parameters, taking into account the risk factors for the development of BOS.Methods. 10,456 patients with Coronavirus Disease-19 (COVID-19) were examined, and 7,459 patients were randomized into 2 groups with a newly diagnosed BOS. Group 1 (n = 3,245) was prescribed beclomethasone/formoterol (BDP/FORM) as Maintenance And Reliever Therapy (MART). Group 2 (n = 4,252) was prescribed budesonide suspension (BUD) and salbutamol solution (SAL). The study assessed severity of COVID-19, presence of atopy and frequency of acute respiratory viral infections (SARS) in the medical history, spirometric parameters, blood eosinophils, Asthma Control Questionnaire-5 (ACQ-5) score, use of pro re nata medications, and adverse events.Results. Patients who had mild COVID-19 were diagnosed with BOS at weeks 8 – 24 (73.3%), while patients with moderate or severe COVID-19 were diagnosed at week 4 (54.9%). Virus-induced BOS (VI BOS) was diagnosed in 71.8% of the cases. 13% of the patients with BOS in postcovid period were diagnosed with asthma.Conclusion. The incidence of BOS is significantly higher in patients with atopy and history of frequent SARS who had moderate or severe COVID-19. A fixed combination of extrafine BDP/FORM as MART was superior to nebulized BUD + SALM in the treatment of VI BOS.По Π΄Π°Π½Π½Ρ‹ΠΌ Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹, ΠΎ взаимосвязи Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2) ΠΈ бронхообструктивного синдрома (Π‘ΠžΠ‘) Π² постковидном ΠΏΠ΅Ρ€ΠΈΠΎΠ΄Π΅ ΠΎΠ΄Π½ΠΎΠ·Π½Π°Ρ‡Π½ΠΎΠ³ΠΎ Π²Ρ‹Π²ΠΎΠ΄Π° ΡΠ΄Π΅Π»Π°Ρ‚ΡŒ Π½Π΅Π²ΠΎΠ·ΠΌΠΎΠΆΠ½ΠΎ.ЦСлью исслСдования являлось ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ ΠΎΠΏΡ‚ΠΈΠΌΠ°Π»ΡŒΠ½Ρ‹Ρ… ΠΏΠΎΠ΄Ρ…ΠΎΠ΄ΠΎΠ² ΠΊ Π»Π΅Ρ‡Π΅Π½ΠΈΡŽ Π½Π° основании комплСксной ΠΎΡ†Π΅Π½ΠΊΠΈ клиничСских, Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹Ρ… ΠΈ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΎΠ½Π°Π»ΡŒΠ½Ρ‹Ρ… ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»Π΅ΠΉ с ΡƒΡ‡Π΅Ρ‚ΠΎΠΌ Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² риска развития Π‘ΠžΠ‘.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is to examine the helminthological status of wild carnivore mammals inhabiting the territory of the Primorsky Krai and to give an epidemiological assessment of their role in maintaining the natural foci of zoonotic infections.Materials and methods. Feces of carnivores were collected in natural habitats of wild animals. Species of animals were identified by the characteristic features of feces and animal tracks. The shape, size, texture and composition of feces were analyzed. The samples were placed in containers with 5% formalin. A part of the material was stored in native form at -12 ΒΊΠ‘. Muscle tissue samples were obtained from animal carcasses. Feces were examined by flotation techniques with a solution of zinc sulfate, the formalin-ethyl acetate sedimentation technique and using an ammonium nitrate solution. After the study, the samples were disinfected by autoclaving at a pressure of 1.5 atm for 2 hours. Muscle tissue samples were examined by digesting in artificial gastric juice using the Gastros device. The species of Trichinella sp. larvae isolated from the positive samples were identified using the nucleotide sequences. In total, 444 feces samples from 13 species of wild carnivore mammals and 449 muscle tissue samples from 13 species were examined.Results and discussion. Wild carnivore mammals inhabiting the territory of the Russian Far East are often infected with various species of helminths localized in the intestine and tissues, which are causative agents of dangerous parasitic zoonoses. A total of 9 species of helminthes in the Siberian tiger (Panthera tigris altaica), 3 species in the Amur leopard (P. pardus orientalis), 2 species in the Eurasian lynx (Lynx lynx), 4 species in the leopard cat (Prionailurus bengalensis), 5 species in the sable (Martes zibellina), 2 species in the yellow-throated marten (M. flavigula), 5 species in the Siberian weasel (Mustela sibirica), 1 species in the American mink (Neovison vison), 2 species in the Asian badger (Meles leucurus), 8 species in the red fox (Vulpes vulpes), 2 species in the raccoon dog (Nyctereutes procyonoides), and 9 species in the brown bear and Asiatic black bear (Ursus arctos and U. thibetanus) were identified at studying of 444 feces samples of wild carnivore mammals in the Primorsky Krai. Among the detected helminths were highly pathogenic for humans: Toxocara cati, Paragonimus westermani and nematodes of the family Capillariidae. Trichinella sp. larvae were detected in 96 samples in the study of 449 samples of muscle tissue from wild carnivore mammals. The above types of helminths are of zoonotic nature. The pathogenic role of accidental infection with helminth species Baylisascaris transfuga has not yet been revealed in humans, that makes this type of bear ascaride potentially dangerous for humans. The studies have shown the widespread prevalence of helminth zoonoses in the Primorsky Krai. These data will help to organize properly the work of people whose jobs involve contact with wild animals

The helminths were collected in autumn of 2019 from pinnipeds caught in the Mechigmenskaya Guba of the Bering Sea in the Chukotka Autonomous Okrug by the method of partial helminthological dissection per Skryabin (gastrointestinal tract). Samples were examined from 6 walruses and 26 seals (13 spotted seals and 13 ringed seals). The helminths found were fixed in 70% alcohol. The helminth species were identified at the Department of Parasitology and Veterinary and Sanitary Examination of the MVA named after K. I. Skryabin using reference literature.Results and discussion. All pinnipeds were infected with nematodes of the family Anisakidae. Mature Pseudoterranova desipiens were found in the walrus (Infection Prevalence = 16.7% with Infection Intensity = 3 specimens/animal), mature Ps. desipiens, as well as Contracoecum osculatum and Anisakis simplex larvae (IP = 30.8% with II from 5 to 57 specimens) were found in the spotted seal, and Ps. desipiens larvae and mature Ps. desipiens were found in the ringed seal (IP = 15.4% with II from 1 to 4 specimens). Thus, only Ps. desipiens were represented by mature stages (females and males), and two other species of anisakids, C. osculatum and A. simplex, were found in the seals in the larval stage.ЦСль исслСдований: ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚ΠΎΡ„Π°ΡƒΠ½Ρ‹ ластоногих Π½Π° Π§ΡƒΠΊΠΎΡ‚ΠΊΠ΅, Π° Ρ‚Π°ΠΊΠΆΠ΅ Π°Π½Π°Π»ΠΈΠ· зараТСнности Ρ€Ρ‹Π± основных промысловых сСмСйств возбудитСлями Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚ΠΎΠ·ΠΎΠΎΠ½ΠΎΠ·ΠΎΠ² Π½Π° основании соврСмСнных Π΄Π°Π½Π½Ρ‹Ρ… Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is to examine the helminthological status of wild carnivore mammals inhabiting the territory of the Primorsky Krai and to give an epidemiological assessment of their role in maintaining the natural foci of zoonotic infections.Materials and methods. Feces of carnivores were collected in natural habitats of wild animals. Species of animals were identified by the characteristic features of feces and animal tracks. The shape, size, texture and composition of feces were analyzed. The samples were placed in containers with 5% formalin. A part of the material was stored in native form at -12 ΒΊΠ‘. Muscle tissue samples were obtained from animal carcasses. Feces were examined by flotation techniques with a solution of zinc sulfate, the formalin-ethyl acetate sedimentation technique and using an ammonium nitrate solution. After the study, the samples were disinfected by autoclaving at a pressure of 1.5 atm for 2 hours. Muscle tissue samples were examined by digesting in artificial gastric juice using the Gastros device. The species of Trichinella sp. larvae isolated from the positive samples were identified using the nucleotide sequences. In total, 444 feces samples from 13 species of wild carnivore mammals and 449 muscle tissue samples from 13 species were examined.Results and discussion. Wild carnivore mammals inhabiting the territory of the Russian Far East are often infected with various species of helminths localized in the intestine and tissues, which are causative agents of dangerous parasitic zoonoses. A total of 9 species of helminthes in the Siberian tiger (Panthera tigris altaica), 3 species in the Amur leopard (P. pardus orientalis), 2 species in the Eurasian lynx (Lynx lynx), 4 species in the leopard cat (Prionailurus bengalensis), 5 species in the sable (Martes zibellina), 2 species in the yellow-throated marten (M. flavigula), 5 species in the Siberian weasel (Mustela sibirica), 1 species in the American mink (Neovison vison), 2 species in the Asian badger (Meles leucurus), 8 species in the red fox (Vulpes vulpes), 2 species in the raccoon dog (Nyctereutes procyonoides), and 9 species in the brown bear and Asiatic black bear (Ursus arctos and U. thibetanus) were identified at studying of 444 feces samples of wild carnivore mammals in the Primorsky Krai. Among the detected helminths were highly pathogenic for humans: Toxocara cati, Paragonimus westermani and nematodes of the family Capillariidae. Trichinella sp. larvae were detected in 96 samples in the study of 449 samples of muscle tissue from wild carnivore mammals. The above types of helminths are of zoonotic nature. The pathogenic role of accidental infection with helminth species Baylisascaris transfuga has not yet been revealed in humans, that makes this type of bear ascaride potentially dangerous for humans. The studies have shown the widespread prevalence of helminth zoonoses in the Primorsky Krai. These data will help to organize properly the work of people whose jobs involve contact with wild animals.ЦСль исслСдований – ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚ΠΎΠ»ΠΎΠ³ΠΈΡ‡Π΅ΡΠΊΠΈΠΉ статус Π΄ΠΈΠΊΠΈΡ… Ρ…ΠΈΡ‰Π½Ρ‹Ρ… ΠΌΠ»Π΅ΠΊΠΎΠΏΠΈΡ‚Π°ΡŽΡ‰ΠΈΡ…, ΠΎΠ±ΠΈΡ‚Π°ΡŽΡ‰ΠΈΡ… Π½Π° Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ ΠŸΡ€ΠΈΠΌΠΎΡ€ΡΠΊΠΎΠ³ΠΎ края, ΠΈ Π΄Π°Ρ‚ΡŒ ΡΠΏΠΈΠ΄Π΅ΠΌΠΈΠΎΠ»ΠΎΠ³ΠΈΡ‡Π΅ΡΠΊΡƒΡŽ ΠΎΡ†Π΅Π½ΠΊΡƒ ΠΈΡ… Ρ€ΠΎΠ»ΠΈ Π² ΠΏΠΎΠ΄Π΄Π΅Ρ€ΠΆΠ°Π½ΠΈΠΈ ΠΏΡ€ΠΈΡ€ΠΎΠ΄Π½Ρ‹Ρ… ΠΎΡ‡Π°Π³ΠΎΠ² Π·ΠΎΠΎΠ½ΠΎΠ·Π½Ρ‹Ρ… ΠΈΠ½Π²Π°Π·ΠΈΠΉ.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    The purpose of the research is studying the distribution of endoparasitoses in bison in various regions of the Russian Federation.Materials and methods. The endoparasite fauna in bison was studied in 2018–2020 in the FSBI Prioksko-Terrasny Nature Biosphere Reserve (Moscow Region), the Bison Nursery of the Siberian Branch of the Russian Academy of Sciences of the Altai Republic, the Bryansk Forest Nature Reserve (Bryansk Region), the Ugra National Park (Kaluga Region), the Vologda Region, and at the Department of Parasitology and Veterinary and Sanitary Expertise of the Moscow State Academy of Veterinary Medicine and Biotechnology – K. I. Skryabin MVA. We studied feces collected from bison of different sex and age groups near feeders in the runs, and in reserves, nurseries and in the wild. A total of 320 samples were collected and examined including 237 samples from the Prioksko-Terrasny Nature Biosphere Reserve, 15 samples from the Bison Nursery, 18 samples from the Bryansk Forest Nature Reserve, 29 samples from the Ugra National Park and 21 samples from wild bison from the Vologda Region. For helminth-coprological studies, we collected fresh feces of bison from the soil surface. The feces were examined according to generally accepted methods. The sequential washing technique was used to diagnose trematodiases, and the Kotelnikov-Khrenov and Fulleborn flotation methods were used to diagnose cestodoses, nematodoses and eimerioses.Results and discussion. The endoparasite fauna of the European bison was most diverse in the Prioksko-Terrasny Nature Biosphere Reserve, where we identified the parasitizing of two species of trematodes, one genus of cestodes, one species and four genera of nematodes and one genus of protozoa. All these pathogens parasitize both as mono- and mixed infections. One species of trematodes, one genus of nematodes and one genus of protozoa have been identified in the Ugra National Park. One genus and two genera of nematodes were found in the Bison Nursery of the Siberian Branch of the Russian Academy of Sciences of the Altai Republic and in the Bryansk Forest Nature Reserve, respectively. The dominant were gastrointestinal strongylatoses.ЦСль исслСдований: ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ распространСниС эндопаразитозов Ρƒ Π·ΡƒΠ±Ρ€ΠΎΠ² Π² Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… Ρ€Π΅Π³ΠΈΠΎΠ½Π°Ρ… Π Π€.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
