The purpose of the research is to study the efficacy of new multicomponent drugs for dogs and cats against arachnoentomosis and helminthosis.Materials and methods. The efficacy of new four-component Insacar Total C Plus Drops for Dogs and Insacar Total K Plus Drops for Cats was studied on target animal species. The experiment included 90 dogs and 82 cats including 38 dogs and 37 cats with monoinfection by ticks (Sarcoptes canis, Demodex canis, Notoedres cati, Otodectes cynotis, family Ixodidae), 39 dogs and 31 cats with monoinfection by insects (Ctenocephalides sp., Linognathus setosus, Trichodectes canis), 13 dogs and 14 cats with infection by helminths (Toxocara canis, T. cati, Toxascaris leonina, Taenia sp.), and 13 dogs and 10 cats with mixed infections. The drug was applied to the skin of the animals in dosages as specified in the instructions for use. The therapy effectiveness was monitored on days 14 and 28, and in case of Notoedres cati and Sarcoptes canis, on day 40.Results and discussion. The efficacy of multicomponent drugs against monoinfections with insects, ixodid ticks, ticks of the genus Demodex and helminths, as well as mixed infections of the dogs and cats was 100% in clinical studies. The efficacy in the cats with notoedric mange was 80%, and 83.4% in the dogs with sarcoptic mange. The advantage of four-component Insacar Total C Plus Drops for Dogs and Insacar Total K Plus Drops for Cats is the presence of several components, namely, imidacloprid, praziquantel, pyriproxyfen, and moxidectin. The unique combination of active ingredients ensures the efficacy of drugs against external and internal parasites including ixodid ticks, and preventive efficacy against entomosis and ixodid ticks for 30 days. The drops for dogs and cats are advisable against mixed infections.

The purpose of the research is to determine the species composition of nematodes from the suborder Strongylata and to study organoleptic and physical and chemical parameters of the Nubian goats’ milk at strongylatoses of the digestive tract. Materials and methods. The study subjects were lactating Nubian goats aged 3 to 5 years from private farms in the Moscow Region. A total of 37 animals were examined. Faeces were studied by flotation methods per Fülleborn and KotelnikovKhrenov. To determine the species composition, partial helminthological dissections per K. I. Skryabin were used. In the infected animals from the experimental and control groups, organoleptic and physical and chemical milk parameters were studied prior to and after therapeutic measures using an anthelmintic with the active ingredient fenbendazole at a dose of 5 mg/kg. The deworming effectiveness was determined by the control test. Physical and chemical milk parameters were determined using an automatic Klever-2 milk analyzer, and organoleptic parameters were determined according to common methods pursuant to the effective GOST.Results and discussion. The lactating Nubian goats infected with gastrointestinal strongylates on the Moscow Region private farms amounted to 100% in the Podolsk Urban Okrug, and 88.2% in the Voskresensk Urban Okrug. The species composition was represented by 8 species, namely, Haemonchus сontortus, Ostertagia ostertagi, Trichostrongylus axei, T. colubriformis, Nematodirus spathiger, N. filicollis, Cooperia оvina, and Bunostomum trigonocephalum. In the pre- and postdeworming milk studies, the organoleptic parameters corresponded to the effective GOST in appearance, texture, color and smell; the sweetish taste was only absent after deworming in the experimental goats. Gastrointestinal nematodes from the suborder Strongylata did not affect the organoleptic parameters of milk. However, the pre- and posttreatment weight fraction of fat changed from 2.90±0.30 to 5.40±0.22% in the experimental group.

The purpose of the research is the study of effects of experimental Trichinella spiralis infection in rats and mice on hematological and biochemical blood parameters of the host at different infection stages.Materials and methods. The experiment was performed on mature outbred male rats and male mice that were infected by T. spiralis larvae orally administered at the rate of 10 larvae/1 g of body weight. Blood samples were taken from the rats at 40 days and 3 months after infection; from the mice, on day 40 after infection. The main parameters of peripheral blood in the rats were determined by a MicroCC-20 Plus hematological analyzer (High Technology, Inc. (USA)) using reagents from Clinical Diagnostic Solutions, LLC (Russia). Biochemical blood parameters in the rats and mice were determined by a Clima MC-15 analyzer, RAL Technical el Laboratoria, S.A. (Spain) using reagents produced by Diakon-DS, CJSC (Russia).Results and discussion. At 40 days and 3 months after the rats were experimentally infected with T. spiralis, we observed a consistent increase in the hemoglobin concentration, erythrocytes and leukocytes, and hematocrit, and a decrease in the alkaline phosphatase activity and ALT, and an increase in total protein. On day 40 after infection in the mice, an increase in total protein was observed as in the rats, and a decrease in blood urea. The changes detected in hematological and biochemical parameters in the rats and mice were associated with the toxic effect of Trichinella infection and the response of the host organism. Such changes are dependent on the infection stage and animal species.

The purpose of the research is to study the fauna of gastrointestinal nematodes of sheep in the European part of the Russian Federation.Materials and methods. The studies were carried out in 2022–2023. The objects for the study were the sets of the gastrointestinal tracts of sheep aged from one to 2.5 years, delivered to the slaughterhouse in the Moscow region from different regions of the Russian Federation, including the Oryol and the Astrakhan regions, the Republic of Dagestan and Stavropol Krai. After slaughter, 10 sets of gastrointestinal tracts were taken by the random sampling method from each batch of delivered sheep. Then, these sets of gastrointestinal tracts were subjected to helminthological necropsy according to the method of K. I. Skryabin (1928). The species of detected nematodes were identified according to K. I. Skryabin et al. (1952) and V. M. Ivashkin et al. (1989).Results and discussion. A different degree of gastrointestinal nematodes infection of sheep has been established in different regions of the European part of the Russian Federation. Thus, the rate of infection in the Oryol region was 80%, in the Astrakhan region – 100%, in the Republic of Dagestan – 100% and in Stavropol Krai – 50%. Sheep were infected with Trichostrongylus colubriformis and Teladorsagia circumcincta with an intensity of infection, on average, 251.86±25.2 and 99.25±9.9 ex./head respectively in the Oryol region; T. colubriformis (242.65±24.3 ex./head), T. circumcincta (76.6±7.7 ex./head.), Haemonchus contortus (6.5±0.7 ex./head) and Marshallagia marshalli (19±1.9 ex./head) in the Astrakhan region; T. colubriformis (89.7±9 ex./head), T. circumcincta (43.6±4.4 ex./head), H. contortus (6.8±0.7 ex./head) and M. marshalli (17.8±1.8 ex./head) in the Republic of Dagestan; T. colubriformis (20.2±2 ex./head) and T. circumcincta (11±1.1 ex./head) in Stavropol Krai. Thus, T. colubriformis and T. circumcincta were the most frequently found nematodes in sheep in all of the four studied regions, and these two species also showed the highest rates of infection. The noted low species diversity of nematodes is obviously associated with the mandatory use of anthelmintic drugs. The studied sheep were treated against parasites (according to the accompanying veterinary documentation). At the same time, the detection of nematodes in treated animals possibly indicates the presence of resistant strains.

The purpose of the research is the study of the current situation on ectoparasite infections in dogs in Moscow considering the season of the year.Materials and methods. The current situation on ectoparasitosis in dogs in Moscow was studied on the basis of the VNIIP – FSC VIEV and OOO GLOBALVET CLINIC (Moscow) in 2020–2022. Ninety-four dogs were examined in different seasons of the year. When examining the animals, attention was paid to pelage and skin damage. The history was taken with the animal sex, age, and pelage and skin state taken into account; the ears were examined; the pelage was combed out using a magnifying glass; ear contents were microscopically examined; and scrapings of the superficial and deep layers of the skin were made. The results were statistically processed using Microsoft Excel.Results and discussion. The infection of the dogs with Demodex canis was the highest possible in the autumn-winter period (7.4%), and in spring and summer it decreased to 5.3 and 4.2%, respectively. Ixodes ricinus ticks were only found on the skin and pelage of the dogs (18%) in the warm season. No significant difference was observed in the infection of the dogs with Otodectes cynotis, Sarcoptes canis and Cheyletiella jascuri in different seasons of the year. The seasonal dynamics of the infection of the dogs with different species of insects varied. Fleas were found in winter in 6.4% of the dogs, and in spring and summer in 8.5% and 10.6% of the dogs, respectively. The infection of the dogs with lice was 3.2% in winter, 4.2% in spring, 5.3% in summer and 6.4% in autumn. The maximum infection of dogs with lice was observed in summer (4.2%), and it decreased in winter to 2.1%.

The purpose of the research is the morphological and molecular identification of trematodes found in the intestines of migratory waterfowl with subsequent taxonomic evaluation.Materials and methods. Mature specimens of trematodes were collected from the intestines of waterfowl (Fulica atra and Aythya ferina) shot during the ecological-faunistic monitoring in the southern part of the Primorsky krai. Preliminary morphological analyze revealed that trematodes belong to the Echinostomatidae family. The whole-mounts of worms from F. atra were prepared using standard methods with alum carmine. Divergent domains of 28S ribosomal RNA gene were sequenced and used to determine systematic position and relationships of discovered species of echinostome by reconstructing Bayesian and Maximum likelihood trees.Results and discussion. Trematodes found in the coots' intestine, should be described as Neomoliniella longicorpa in the new genus Neomoliniella gen. et sp. nov., which is reliably confirmed by morphological and genetics data. Another cryptic echinostomatid species sister to Neomoliniella gen. nov., and probably representing the separate unknown genus, was demonstrated only on the phylogenetic reconstructions and confirmed by large genetic distances. Currently, this taxon is indicated as Echinostomatidae gen. sp. and more evidence is needed for its validation. We also report about the first detection of Echinostoma paraulum from A. ferina in the south of the Russian Far East. The biology, morphology of each life cycle stage of newly described species of worms should be investigated to test not only their scientific but also medical significance. For the first time in the history of the group, dichotomous keys for eight families of the superfamilyEchinostomatoidea and, to date, the largest of all previously known for the family Echinostomatidae identification chart – dichotomous keys for the identification of 27 Palearctic genera were compiled.
本研究的目的是对迁徙水禽肠道内的吸虫进行形态学和分子鉴定，并进行分类评价。材料和方法。在滨海边疆区南部进行生态-动物监测时，从水禽(Fulica atra和Aythya ferina)的肠道中采集了成熟的吸虫标本。初步形态分析显示吸虫属棘口虫科。采用明矾胭脂红标准方法制备了全虫。对28S核糖体RNA基因的不同结构域进行了测序，并通过重建贝叶斯树和极大似然树来确定已发现棘口动物物种的系统位置和相互关系。结果和讨论。在白骨顶肠道内发现的吸虫，应描述为新属Neomoliniella gen. et sp. nov.中的Neomoliniella longicorpa，形态学和遗传学资料可靠地证实了这一点。另一种与Neomoliniella gen. nov.有亲缘关系的隐蔽棘孔虫，可能代表了一个独立的未知属，仅在系统发育重建中得到证实，并通过大的遗传距离得到证实。目前，该分类群为棘口虫科(Echinostomatidae gen. sp.)，需要更多的证据来验证。我们还报道了在俄罗斯远东地区南部首次发现ferina棘孔虫的副棘孔虫。对新发现的虫种的生物学和每个生命周期阶段的形态学进行研究，不仅要检验它们的科学意义，而且要检验它们的医学意义。这是该类群历史上第一次编制了棘孔虫总科8个科的二分类键，也是迄今为止已知的最大的棘孔虫科鉴定图——27个古北区属的二分类键。
