Today, helminth infections in horses are one of the important problems for veterinary specialists, since the action of helminths significantly affects the general condition of horses, allergic and toxic manifestations of diseases are observed, external qualities deteriorate, and performance, endurance, and natural resistance are reduced, which leads to diseases of various etiologies. We set a goal to study seasonal features of the epizootic process of helminthiasis in horses in the Tyumen Region. The work was carried out in 2020 on the basis of the Laboratory of Innovative Horse Breeding of the Institute of Biotechnology and Veterinary Medicine of the State Agrarian University of the Northern Trans-Urals, the Tyumen Regional Hippodrome, and Allegro and Olympia equestrian clubs. A total of 312 animals were examined. The diagnosis was confirmed by common laboratory research methods. As a result of our studies, it was found that the maximum invasion prevalence caused by helminths Parascaris equorum was recorded in the autumn-winter period, and the minimum in the springsummer period; the invasion with Strongyloides westeri caused by causative agents from the suborder Strongylata was observed in the spring-summer-autumn period, and the minimum in winter, and the invasion with Oxyuris equi was recorded in early spring and minimal invasion in summer.

The regional assessment of the fauna of gall-forming arthropods on the vegetation of urban ecosystems in North Ossetia indicates a significant distribution of pests. Ticks with the prevalence of 62.5% dominate in the structure of phytophagans of the studied plants in Vladikavkaz. The proportion of gall-forming insects is 37.5%. Of the 25 species of studied plants, 8 are susceptible to arthropod attack. Gall-forming insects infect laminas of two types of trees and one type of shrub. Thus, the willow gall sawfly (Pontania proxima) was identified on the goat willow (Salix caprea), the elm-grass root aphid (Tetraneura ulmi) on the elm rough (Ulmus glabra), and the red currant aphid (Cryptomyzus ribis) on the golden currant (Ribes aureum). Gallforming mites inhabiting laminas of four types of trees and one type of shrub. Walnut leaf gall mite (Eriophyes tristriatus) was detected on the walnut (Juglans regia), the grape leaf rust mite (Calepitrimerus vitis) on the common grape (Vitis vinifera), the pear blister mite (Eriophyes pyri) on the pear Nart (Pyrus "Nart"), the maple gall mite (Aceria macrorhyncha) on the sycamore maple (Acer pseudoplatanus), and the red nail gall mite (Eriophyes tiliae) on the Caucasian linden (Tilia caucasica).

Toxocariasis is both a veterinary and medical problem worldwide. A feature of Toxocara biology is that Toxocara larvae commit visceral larva migrans, damage the liver, lungs, and other organs and tissues in non-specific hosts, including humans. Constant reinvasion leads to the accumulation of stage 2–3 larvae in the body of nonspecific (paratenic) hosts. The problem of parasitological contamination of soil on the territory of rabbit farms and the risks of infection of rabbits were considered. Therefore, it became necessary to study the involvement of the rabbit as a paratenic host in toxocariasis. An experiment was conducted on Soviet Chinchilla rabbits. Toxocara eggs were administered orally. Hematological parameters were examined according to common methods. In order to identify specific IgG antibodies, blood serum was examined by enzyme immunoassay (ELISA). IgG present in the rabbits’ blood serum with a positive titer (1:100) in ELISA allows us to conclude that rabbits along with other animals are paratenic hosts of Toxocara canis. Hematological parameters in the animals of the experimental and control groups did not have significant differences and were within the physiological range throughout the entire experiment.

This article discusses current methods of using insecticidal preparations of the synthetic pyrethroid group to protect livestock animals from insects of the midges complex. Synthetic pyrethroids are the most widely used group of insecticides, and their use in agriculture is considered to be the most effective and least toxic in the insect control. The article analyzes insecticide application methods and compares advantages and disadvantages of each method. The effective method today is ultralow-volume spraying. This method is effective as it saves time spent on treatments and has a long-lasting insecticidal effect. Another popular method is a pour-on method which uses an insecticide applied to the withers along the spine. These treatments are highly effective and safe for personnel but require an individual approach, which takes a lot of time. The most environmentally friendly method is polymer insecticide ear tags attached to the animal's auricle, but it only protects the head, neck and front of the back. It is concluded that the choice of the method depends on the task and the current trend towards environmental friendliness, while the most promising methods for further development are pour-ons and insecticide ear tags.

There are not so many comprehensive studies for helminthological contamination of urbanized environment of the northern part of Belarus with eggs of helminths of carnivores including domestic ones. The routine examination for environmental contamination by helminth eggs carried out by the Sanitary and Epidemiological Services is limited to foci of incidence in humans. This determines the need for constant monitoring of parasitic contamination of environmental objects on urbanized territories of the northern part of Belarus. The article contains data on the species diversity of helminths in domestic carnivores found in the soil of the selected area. 813 soil samples were taken and analyzed. Twelve helminth genera were identified, namely, Toxocara spp., Toxascaris spp., E. granulosus, Taenia spp., Dipylidium spp., Ancylostoma spp., Uncinaria spp., Strongyloides spp., Trichocephalus spp., Capillaria spp., Mesocestoides sp., and Alaria sp., which belong to three classes, Trematoda, Cestoda, and Nematoda. The highest prevalence in both urban and rural areas was observed for representatives of the genus Toxocara. The helminth species diversity in urban areas exceeded that in rural areas. The found species were represented by bio- and geohelminths. Eight of the species found belong to the group of zoonotic helminths: T. canis, T. leonina, D. caninum, A. caninum, U. stenocephala, T. vulpis, E. granulosus, and A. alata.

Waterfowl are a very common ecological bird group including up to 30% of the species composition, and sometimes up to 40% of the total number of all birds in the ornithocomplex. Thirty five to forty waterfowl species are found in the Kursk Region taking into account birds of passage. The most numerous are mallards, European teals, wigeons, northern shovelers, pintails, golden-eyes, and common pochards. The biological diversity of endoparasites can have various effects on the vital activity of waterfowl. For some species, helminthiasis leads to inhibition of vital processes, and for others, infection can lead to death. The results of helminthological studies of waterfowl identified 6 nematode species, 10 trematode species and 3 cestode species. Among the ectoparasites found in wild and domestic birds, the leading species in terms of diversity and wideness of distribution were biting lice, 6 species; gamasid mites, 2 species; and fleas, 1 species. The occurrence and spread of various helminth infections among waterfowl are influenced by such factors as the type of terrain, the presence or absence of a reservoir, the host biology and the nature of its nutrition. The flights and seasonal migrations of wild birds lead to the emergence of new foci of parasitic diseases in domestic and wild waterfowl.

On Tyuleny Island, the largest reproductive rookery of the sea lion is located that is formed by migratory specimens. The research purpose was to study the spread of uncinariasis in sea lions and to determine its infection rates. The studies were conducted from June 20 to August 12, 2021. The carcasses of dead cubs were collected on the western beach (WPL) in the area of sites 10, 11, and 12. The dead animals were subjected to helminthological dissection taking into account the recommendations for the collection of helminthological material from marine mammals. A comparative analysis of the recorded number of cubs allowed us to detect a trend to its increase. During the period of field studies, 2382 puppies were recorded including 2195 alive, and 187 dead specimens. In comparison with 2020, the number of young animals increased by 258 individuals, but the invasion prevalence also increased by 2.8%. The epizootic process had age and seasonal dynamics. The cause of death of puppies in the first days after birth were injuries and exhaustion. Mortality from uncinariasis according to preliminary data was recorded in cubs aged 15-30 days. The average rate of invasion intensity per specimen was 2004.2±325.7 specimens (937–4360). No significant differences between the sex groups were detected.

The article highlights some features of the long-term dynamics of infection of livestock animals with cysticercosis. Significant differences are shown in the detection of cysticercosis in pigs and cattle in postmortem diagnostics at enterprises of various types. An analysis of the epizootic situation on cysticercosis of livestock animals was carried out using materials from the veterinary and sanitary examination of raw materials and products of animal origin (Form 5-vet) for 2009–2020. The infection of animals with Cysticercus cellulosaе and Cysticercus bovis was assessed using the conventional method. It was established that the Novosibirsk Region was contaminated with cysticercosis of livestock animals. Finnosis of cattle is recorded annually with infection rate varying from 0.09 to 0.01%, however, cysticercosis of pigs has been detected since 2018. The average cysticercosis infection rate in cattle and pigs was 0.03 and 0.005%, respectively. The leading role in the postmortem diagnostics of finnosis in cattle belongs to meat processing plants. During the research period at meat processing plants, slaughterhouses and markets, 814, 59 and 93 cases of finnosis in cattle were identified respectively, which was 84.0, 6.0 and 10.0%.

Significant differences are shown in the \u0000detection of cysticercosis in pigs and cattle in postmortem diagnostics at enterprises \u0000of various types. An analysis of the epizootic situation on cysticercosis of livestock \u0000animals was carried out using materials from the veterinary and sanitary examination \u0000of raw materials and products of animal origin (Form 5-vet) for 2009–2020. The infection of animals with Cysticercus cellulosaе and Cysticercus bovis was assessed \u0000using the conventional method. It was established that the Novosibirsk Region was \u0000contaminated with cysticercosis of livestock animals. Finnosis of cattle is recorded \u0000annually with infection rate varying from 0.09 to 0.01%, however, cysticercosis of \u0000pigs has been detected since 2018. The average cysticercosis infection rate in cattle \u0000and pigs was 0.03 and 0.005%, respectively. The leading role in the postmortem \u0000diagnostics of finnosis in cattle belongs to meat processing plants. During the \u0000research period at meat processing plants, slaughterhouses and markets, 814, 59 and \u000093 cases of finnosis in cattle were identified respectively, which was 84.0, 6.0 and \u000010.0%.

Analysis of histologic specimens made from trematodes according to the generally accepted method before and after the action of anthelmintics and stained in a Schick test for the detection of glycogen, and with bromophenol blue for proteins, and toluidine blue for hexosaminoglycans using light microscopy showed that the action of the preparation in the body of trematodes caused metabolic disorders. After the action of anthelmintics, the histochemical reactivity of the connective tissue of trematodes, the parenchyma, changed. Tissue reaction to the dye increased, decreased or was absent. Weakened or disappeared metachromatic staining indicates a decrease in the amount of acid mucopolysaccharides. The Schick test demonstrates that after the action of the anthelmintic on the parasite, glycogen disappears, and the carbohydrate components are redistributed and quantitatively changed. A change in color when stained with bromophenol blue for proteins indicates a change in their nature and destruction. Histochemical analysis provides information on the quantitative and qualitative content of carbohydrate and protein compounds in the trematode parenchyma and objectively allows us to reveal the change in their ratio and nature after anthelmintics, and therefore to establish the mechanism and effect of drugs on the homeostatic disruption in the parasite's body after the host undergoes chemotherapy.

The study of the species composition of ectoparasites and the functioning of the parasitic system with the participation of specific groups of vertebrates in certain climatic zones is of scientific and practical interest. In this regard, the clarification of the parasitological situation in predatory mammals in the system "ectoparasites – predatory animals" in the biogeocenoses of Uzbekistan is an urgent task of fundamental and applied parasitology. For the first time, the features of the species composition of the ectoparasite fauna in domesticated (dog, cat) and wild (jackal, wolf, fox, jungle cat) predatory mammals from Uzbekistan were studied. Twenty three species of ectoparasites, mites and insects, were found on the studied predators. Ticks in our material are represented by 14 species belonging to the families Ixodidae (12 species), Sarcoptidae (1 species) and Demodicidae (1 species). The bulk of them are ixodid ticks among which representatives of the genera Haemaphysalis (3 species) and Rhipicephalus (4 species) dominate. The insects turned out to be representatives of five families: Trichodectidae (1 species), Linognathidae (1 species), Pulicidae (4 species), Culicidae (2 species), and Hippoboscidae (1 species). In terms of frequency of occurrence and species composition, fleas occupy a leading position. The number of arthropod species per infected host (for example, dogs) ranged from 3 to 7.
