The purpose of the research is to describe and analyze the qualitative and quantitative composition of pink salmon helminths of southeastern Sakhalin.Materials and methods. Standard parasitological methods of collecting material were used. At the autopsy, the ureters, eyeballs, gill petals and arches, and the brain of fish were not examined. The method of collecting salmon parasites in the laboratory has been unchanged since 1992. Collections of representatives of monogenetic suckers were not carried out. Parasitological studies of pink salmon of southeastern Sakhalin were carried out from 1992 to 2022, a total of 4163 fish specimens were examined. The fish is caught in the estuaries of rivers and the sea coast.Results and discussion. According to the results of their own research and literature data, the pink salmon helminth fauna of southeastern Sakhalin is represented by 23 species: Dibothriocephalus nihonkaiensis pl., Eubothrium salvelini, Eu. crassum, Nybelinia surmenicola pl., Pelichnibothrium speciosum pl., Tetraphyllidea gen. sp., Brachyphallus crenatus, Cryptocotyle sp. mtc., Hemiurus levinseni, Lecithaster gibbosus, Prosorhynchoides gracilescens, Parahemiurus merus, Derogenes varicus, Capiatestes thyrsitae, Corynosoma strumosum l., Echinorhynchus gadi, Bolbosoma caenoforme juv., B. bobrovoi juv., Rhadinorhynchus trachuri, Anisakis simplex l., Ascarophis pacifica, Ascarophis skrjabini, Hysterothylacium aduncum. The qualitative composition of the helminth fauna is currently undergoing minor changes, while the quantitative characteristics of some helminths are significantly reduced. Thus, the infection of pink salmon with Bolbosoma sp. juv scrapers. decreased to 0.61±0.18.

The purpose of the research is to establish the prevalence of vector-borne diseases in reindeer (Rangifer tarandus) Bolshezemelskaya and Malozemelskaya tundra.Materials and methods. The research was carried out in 2022–2023 on domesticated reindeer living in the Bolshezemelskaya and Malozemelskaya tundra of the Nenets Autonomous Okrug and the Komi Republic. Stabilized blood was obtained from animals by random sampling and PCR studies were performed for the presence of genetic material of pathogens of the genera Anaplasma, Babesia and Theileria.Results and discussion. The DNA of the causative agent of anaplasmosis was isolated from 14.3% of reindeer from Malozemelskaya (family-tribal community «Vy Tu» (VTU) and «Opseda» (OPS)) and 30.6% of Bolshezemelskaya tundra (Аgricultural production cooperative «Harp» (HARP) and Collective Farm «Izhemsky olenevod and Co» (IZHM)). To a greater extent, vazhenki and calves were infected with anaplasmosis, to a lesser extent – choirs. Genetic material of Babesia pathogens was found in 53.1% of VTU and OPS deer and 36.7% of HARP and IZHM, while babesiosis was most often observed in the chorus group. Teileriosis was found in 10.2% and 4.1% of animal samples among the herds of the Malozemelskaya and Bolshezemelskaya tundra, respectively. The genetic material of the causative agent of teileriosis was isolated mainly from the blood obtained from calves. The causative agent of theileriosis was not found in the biological material of the choirs. The presence of DNA Anaplasma spp. and Babesia spp. in one sample, the proportion of deer from Malozemelskaya tundra herds was 2.4%, from Bolshezemelskaya – 26.5%. The combined course of babesiosis and teileriosis was found to be 8.2% only in VTU and OPS deer. Thus, studies have shown that vector-borne diseases is widespread among the reindeer of the studied farms of the Bolshezemelskaya and Malozemelskaya tundra.

The purpose of the research is a comparative study of morphological changes in Trichinella spiralis capsules and larvae in the lynx and laboratory animals.Materials and methods. The experiment used striated muscle tissue from spontaneously infected lynxes and from white rats experimentally infected with T. spiralis larvae isolated from wild animals in the Kirov Region. Morphometric studies of T. spiralis capsules and larvae in the lynx muscle tissue were conducted on temporary histologic specimens.Results and discussion. Lemon-shaped (50%) and oval (40%) capsules were found in the entire muscle mass of the white rats, and only 10% of the larvae were round in shape. The lynx was not found to have lemon-shaped capsules; oval (60%) and round (40%) capsules predominated. The studies show that the parasite capsule size and shape indicate the adaptive abilities of T. spiralis to various types of host muscle tissue and their morphological characteristics, and are largely determined by the symplast structure and size.

The purpose of the research is to analyze the economic efficiency of planned antiparasitic deworming in sheep-breeding farms by the veterinary service of the region.Materials and methods. The studies were carried out using statistical data from the Veterinary Directorate of the Stavropol Territory for 2015-2019 and guidelines for determining the economic efficiency of antiparasitic measures. Economic losses were estimated at regional purchase prices for livestock products as of 2019. The calculations used indicators such as morbidity, mortality, and specific losses of the main product (meat, wool) per sick animal. The economic efficiency of veterinary measures for parasitic diseases of sheep was determined by the indicator of the prevented economic damage.Results and discussion. Analysis of the results of the treatment of sheep by the veterinary service of the region over a five-year period for the prevention of parasitic diseases showed that they annually carry out a large amount of antiparasitic treatments, but it should be noted that their number for all infestations decreased in 2019 compared to 2015 from 10180.0 thousand to 5231.0 thousand. Actual economic damage from parasitic diseases amounted to 10343.5 thousand rubles, and the amount of economic damage prevented as a result of planned deworming of sheep was 3.6 times higher than the amount of actual economic damage and amounted to 37895.7 thousand rubles.

The purpose of the research is studying current fauna of helminths in wild artiodactyls and analysis of their ecological relationships with populations of representatives of the Artiodactyla in biogeocenoses of Karakalpakstan.Materials and methods. Wild populations of artiodactyls were studied in 2016–2020 in the ecosystems of the Kyzyl Kum, Ustyurt and the lower reaches of the Amu Darya, including the drained bottom of the Aral Sea. Some killed animals (the saiga, Persian gazelle, and Bokharan deer) seized from poachers, as well as those killed by predators and feral dogs in the sanctuaries and reserves of Karakalpakstan were used to collect helminthological material. Wild boars were examined after shooting during the hunting season. A total of 11 saigas, 13 Persian gazelles, 7 Bokharan deer and 16 wild boars, and 213 fecal samples from these animals were examined. The studies were carried out using generally accepted methods of dissection (Skryabin, 1928; Ivashkin et al., 1971) and ovoscopy of animal feces. For a comparative analysis of helminth fauna of the study animals, we used previously collected (1959–1978) parasites from the wild boar, saiga, Persian gazelle and Bokharan deer in Karakalpakstan.Results and discussion. We have found that the fauna of the Artiodactyla is represented by the following 5 species in the biogeocenosis of Karakalpakstan: Sus scrofa nigripes Blan., Cervis elaphus bactrianus Lydek., Gazella subgutturosa Gueld., Saiga tatarica Linn., and Ovis orientalis arcal Gmel., in which we identified 26 helminth species classified as Cestoda, Trematoda and Nematoda. Cestodes are represented by 6 species, trematodes by 2 species, and nematodes by 18 species. The helminth species composition of the study animals is 14 species in pigs, 11 species in Bokharan deer, 13 species in saigas and 14 species in Persian gazelles. Representatives of the genera Taenia, Echinococcus, Fasciola, Schistosoma, Gongylonema and Setaria are common to these animal species. By nature of the biological cycle, the helminths of the study artiodactyls recorded by us can be divided into two groups: monoxenous and heteroxenous. Monoxenous parasites include representatives of the Trichocephalidae (3 species), Trichostrongylidae (2 species), Dictyocaulidae (2 species), Syphaciidae (1 species), and Ascarididae (1 species), whose life cycles proceed without changing hosts. Eighteen species of representatives of cestodes (6 species), trematodes (2 species) and nematodes (10 species) are developed with the involvement of intermediate hosts.
本研究的目的是研究野生偶蹄动物中目前的蠕虫区系，并分析它们与卡拉卡尔帕克斯坦生物地沼中偶蹄动物代表种群的生态关系。材料和方法。2016-2020年，在克孜勒库姆、乌斯季乌特和阿姆河下游生态系统(包括咸海排水底部)研究了偶蹄动物的野生种群。从偷猎者手中捕获的一些被杀死的动物(赛加羚羊、波斯瞪羚和博哈兰鹿)，以及在卡拉卡尔帕克斯坦的保护区和保护区被捕食者和野狗杀死的动物，被用来收集蠕虫学材料。在狩猎季节，对野猪进行射击后的检查。共检测了11只赛加羚羊、13只波斯瞪羚、7只博哈罕鹿和16只野猪，以及213份粪便样本。这些研究是使用普遍接受的解剖方法进行的(Skryabin, 1928;Ivashkin et al.， 1971)和动物粪便卵镜检查。为了对研究动物的寄生虫区系进行比较分析，我们使用了以前在卡拉卡尔帕克斯坦(Karakalpakstan)从野猪、赛加羚羊、波斯瞪羚和Bokharan鹿收集的寄生虫(1959-1978)。结果和讨论。我们发现，在卡拉卡尔帕克斯坦的生物地质群落中，偶蹄动物的区系有以下5种:Sus scrofa nigripes Blan。;;;;;Gazella subgutturrosa Gueld;;;;;以及东方橄榄(Ovis orientalis arcal Gmel)。，共鉴定出蠕虫26种，分类为虫、吸虫和线虫。虫类6种，吸虫类2种，线虫类18种。研究动物的寄生虫种类组成为猪14种，鹿11种，赛加羚羊13种，波斯瞪羚14种。带绦虫属、棘球绦虫属、片形吸虫属、血吸虫属、巩膜绦虫属和尾尾虫属是这些动物物种常见的代表。根据生物循环的性质，我们所记录的偶蹄类蠕虫可分为单系和异系两类。单源寄生虫包括毛头虫科(3种)、毛圆虫科(2种)、盘虫科(2种)、梅毒虫科(1种)和蛔虫科(1种)的代表，它们的生命周期不改变宿主。在中间寄主的参与下，已发育出绦虫(6种)、吸虫(2种)和线虫(10种)等代表性昆虫18种。

The purpose of the research is studying the duration of the chemoprophylactic effect of prolonged solutions of DAC (diminazene aceturate) in combination with a solution of glycerin in bovine pyroplasmidoses.Materials and methods. 300 cattle were examined at the farms of the Kizilyurt and Kumtorkalinsky Districts of the Republic of Dagestan for tick infection. 45 blood smears were examined. Three groups of animals of 15 animals each were formed according to the principle of analogues. The first control group was administered DAC without glycerol, and the experimental groups were given prolonged solutions of DAC in combination with glycerin 10–12 days after the animals were sent to the pasture with rare solutions of acaricides during the mass tick infection period. The drug was administered intramuscularly at a dose of 4–5 ml per 100 kg of body weight. Animals were observed during the season; in case of any change in general condition, thermometry was performed, and blood smears were examined.Results and discussion. 5% aqueous solution of DAC in combination with a solution of glycerol provides prophylaxis of pyroplasmidoses in cattle. The chemoprophylactic effect of 5 % aqueous glycerol solution of DAC is kept in the animal body for 25 days. Its 6 times' use ensures the well-being of animals during the season (from April to September).

The purpose of the research is to determine the therapeutic efficiency of the moxidectin-based domestic anthelmintics and develop protocol of medical and preventive activities in dog's dirofilariasis under the conditions of Central Black Earth Region of Russia. Materials and methods. Blood from ill dogs infected naturally with both species of dirofilariases that was tested for presence of helminths' larvae by Millipore® (Ireland) membrane filter method served as the material for the research. Experimental groups were formed out of 76 infected with dirofilariasis dogs aged 1-14 years under the principle of analogs to determine the therapeutic efficiency of moxidectin-based domestic anthelmintics. Drugs weren’t administered into intact animals of the first group (n = 21). MKTc Ankir-B® in the dose of 500 mg per animal was administered orally to animals of the second group (n = 19) as placebo. Inspector Total C anthelmintic was administered in the single dose of 2.5 mg per kg of body weight to the third group of dogs (n = 19) epidermally, Helmimax anthelmintic was administered in the single dose of 0.25 mg per kg of body weight orally to animals of the fourth group (n = 17). During experiments animals were examined clinically and hemolarvoscopically before administration of drugs and on the 3rd, 14th, 30th, 45th and 60th day after administration. Results and discussion. Inspector Total C anthelmintic in the dose of 2.5 mg per kg according to an active substance in the form of spot-on and Helmimax anthelmintic in the dose of 0.25 mg per kg according to an active substance in single administration in dogs infected with Dirofilaria immitis and D. repens species dirofilariasis have 100 % microfilaricidal efficiency. Anthelmintics do not change physiological parameters, do not cause side effects and well tolerated by animals. It should be noted that drugs therapeutic action starts on the third day after treatment regardless of the infection intensity and germ's species. Complete demolition of dirofilariasis adult stages are achieved in chronic administration during 6 months (once per month).
