Since 1953, Kazakhstan has been working on the acclimatization of the kulan. For the first time, two species of protozoa (Eimeria hemionus, Eimeria pinaevae) were recorded in the kulan 30 years ago. In the present work, three helminth species (Alfortia edentatus, Strongylus equinus, Strongyloides westeri) were identified in the kulan, which were not previously observed in it. Three fecal samples from kulans that were kept in the Ile-Balkhash State Nature Reserve were delivered to the parasitology laboratory. The material was processed according to the Fülleborn method. It is known that Eimeria have strict host specificity, that is, animals can only become infected with certain types of Eimeria. Perhaps during acclimatization, kulans could bring these parasites from the reserve of Turkmenistan. Helminths (Alfortia edentatus, Strongylus equinus) could infect kulans in a new habitat where they graze along with horses. At the same time, the living conditions are the same for both species of animals. Geohelminths Strongyloides westeri are able to reproduce outside the animal body. Infection occurs in an alimentary way. At the same time, kulans could become infected with them during their rest. It is probable that new species of parasites will be registered in kulans in the coming years.

The immunocytochemical study of cestode larvae, Mesocestoides vogae tetrathyridia (Cestoda, Mesocestoididae) detected serotonin-immunopositive neurons and fibers in the central and peripheral nervous system. The wholemounts were analyzed by confocal laser scanning microscopy. The size of serotonergic neurons, and the distance between the lateral nerve cords, and between the commissures were measured for the first time in the head, middle, and posterior regions of the larvae. Serotonergic nerve components of the M. vogae larvae were detected in the nerve ganglia in the head located between four suckers on the anterior part, as well as between clearly visible three pairs of lateral, dorsal, and ventral longitudinal nerve cords connected by transverse commissures. The distance between the lateral nerve cords was 130.90±33.92 µm, and between the commissures, 24.66±6.02 µm. Sizes of M. vogae’s neurons were as follows: length, 9.84±1.97 µm, and width, 7.19±1.50 µm. The largest serotonergic neurons were observed in the head region of the cestodes. The neurons in the head and middle regions of the body demonstrated the most intensive staining. The results indicate wide spreading serotonin in flatworms which is already found in the early stages of their life cycle.

The geography of human cercariasis is extensive. It covers urbanized areas of many modern metropolitan cities. Cercariasis is also known in the inland waters of the Amu Darya and Zarafshan River basins (within Uzbekistan). The causative agents of cercariasis consist of two clearly differentiated cercariae groups: Schistosoma and Bilharziella. The article presents the results of field and experimental studies on nonspecific human cercariasis caused by cercariae Schistosoma turkestanicum and Trichobilharzia ocellata in various reservoirs of Uzbekistan. In this paper, the studies were conducted in Uzbekistan in 2020–2022. The material was collected in the delta and floodplain reservoirs of the Amu Darya and Zarafshan rivers. The material was collected in the deltaic and bottomland water bodies of the Amu Darya and Zarafshan Rivers which were intensively visited by water birds and mammals. In different seasons of the year, spring, summer, and autumn, more than 25 thousand specimens of freshwater mollusks belonging to the families Lymnaeidae, Planorbidae, Physidae and Thiaridae were collected and studied. Morphological study of cercariae was conducted. In different types of reservoirs, the population of mollusks, intermediate hosts, of discussed trematodes, turned out to be quite high. Their total infection with parthenita and the cercariae bilharzia ranged from 0.3 to 6.2% in Lymnaeidae, and 4.0% in Melanoididae. Schistosome larvae (Sch. turkestanicum) infection was only recorded in Lymnaea auricularia (Lymnaeidae), which was 12.6 to 22.6%.

Deworming untamed herd horses is a difficult task. It is more convenient to use drugs by free feeding, individually or in groups in a mixture with concentrated feed. In this regard, we have developed a new dosage form for the treatment and prevention of parasitosis in herd horses by free feeding in a mixture with concentrated feed based on the substance ivermectin, which has a high antiparasitic activity and a wide spectrum of action. To obtain an antiparasitic supramolecular complex based on the substance ivermectin, an innovative mechanochemical technology was used using two water-soluble polymers of low molecular weight polyvinylpyrrollydon-17 and natural arabinogalactan. The aim of the work is to develop a methodology for the use of the supramolecular complex ivermectin "Aniverm-2.0%" against parasitosis of herd horses. The drug "Aniverm-2.0%" is a supramolecular complex of ivermectin, a water-soluble solid powder of a light beige color, tasteless, with an easily perceptible coniferous odor. The methodology provides a brief description of the drug, its mechanism of action, pharmaco-toxicological properties, the procedure for use, the timing of slaughtering animals and personal safety measures. According to the degree of impact on the body of warm-blooded animals, the drug "Aniverm-2.0%" belongs to low-toxic substances.

Our research is devoted to the study of the prevalence of leishmaniasis (on the example of identified cases) in stray dogs in the Syunik and Ararat Regions of Armenia. In May 2022, in the settlements of the Syunik and Ararat Regions of the Republic, we examined five stray dogs, outbred females aged from 6 months to 2 years for leishmaniasis. One dog was examined in the cities of Meghri, Kapan and in the village of Tegh, Syunik Region. Two dogs were examined in the village of Yeraskh, Ararat Region. Our studies have shown that the invasion prevalence (IP) in the population of stray dogs in the Syunik and Ararat Regions of Armenia is 100%. The examined animals looked quite healthy and felt good. Skin lesions in the form of epithelium desquamation on the nose were only recorded in one dog (20%) in Kapan, Syunik Region. Thus, we confirmed that in the Syunik and Ararat Regions of Armenia, a local natural focus of leishmaniasis is actively functioning, in the spread of which stray dogs are actively involved, which indicates the circulation of parasites in the study area and the possibility of infection of other animals and humans through carriers. Prevention and control measures of leishmaniasis should include measures to control the number of stray dogs, control the incidence in domestic dogs using serological tests, and measures to destroy mosquito breeding sites.

The research purpose was to study the distribution of the main Strongylata infections of horses in the provinces of the Altai Republic. Infective larvae of strongylates after their cultivation were isolated by the Berman-Orlov method and subsequently identified taking into account morphometric characteristics. The ubiquitous distribution of helminths of the suborder Strongylata with heterogeneity of infection in ungulates was detected in the context of administrative districts and provinces. In the provinces as a whole and in administrative districts, species of the family Trichonematidae predominate, and their infection rate in horses significantly exceeds the infection with other strongylates (IP, 64–99%). The infection rate of nematodes of the family Strongylidae, including Strongylus, Alfortia and Delafondia is 2–4 times smaller and is 31.9, 20.4 and 10.6%, respectively. On the farms of the Southeastern Altai (Kosh-Agachsky District), the invasion of ungulates with strongylates in general including Trichonema, Alfortia and Delafondia is 2-10 times lower than in other districts of the Republic and amounts to 59.6, 51.6, 4.8 and 3.2%, respectively. The sharp difference in the infection of animals in this region in our opinion is mainly associated with the topographic and landscape features of the area and is due to the low heat supply and aridity of the climate in most of the territory.

To control helminth infections in carnivores, scientists and practitioners have proposed a number of drugs and agents against both endogenous and exogenous stages. The problem of toxocariasis in carnivores continues to pose challenges for researchers, namely, to improve measures to control the exogenous stage of egg development. Of the modern drugs used against the exogenous stages of Toxocara egg development in carnivores, we should note chlorine-, phenol-, iodine-, caustic alkalis-based drugs and others which are mostly monovalent and do not meet the requirements of veterinary practice in terms of their efficacy. Based on the above, we set ourselves the task of testing the ovocidal activity of the combined agent Сystodesis consisting of glutaraldehyde, alkyldimethylbenzylammonium chloride, isopropyl alcohol, and polyethylene glycol-400 against Toxocara canis eggs in an in vitro laboratory experiment. The combined agent of disinvasion Сystodesis at 3% concentration showed 94.06% intense-effectiveness in an in vitro laboratory experiment against Toxocara canis eggs. The intense-effectiveness of the test agent at 4 and 5% concentrations against Toxocara eggs in dogs was 100%. The comparator 4% phenol provided 86.5% intense-effectiveness.

The study of the Trichinella distribution in representatives of different systematic taxa is quite relevant as it allows us to establish the role of infected animals in the functioning of the parasitic system of the causative agent of trichinellosis. Scientific works contain contradictory information on the presence of the Trichinella infection in rodents and insectivores. Many scientists publish data on the detection of Trichinella in species of these orders of mammals. There is a large number of works showing the absence of the Trichinella invasion in different species of rodents and insectivores. The purpose of our research was to study the Trichinella infection rate in rodents and insectivores in the Kursk Region. Trichinella larvae were detected by compressor trichinelloscopy and by the method of digesting muscle tissue in artificial gastric juice. Capsule-forming Trichinella (Trichinella spp.) were found in the muscles of infected animals. In total, 7 species of rodents and 5 species of insectivores were studied. The Trichinella invasion was detected in the common vole (1.8%) and in Erinaceus roumanicus (4.2%). The results obtained show that rodents and insectivores are involved in the circulation of Trichinella in the Kursk Region. We believe that representatives of these orders of animals serve as one of the sources of infection for many species of predatory mammals.

The purpose of this work is to identify the infection of the Mongolian racerunner Eremias argus Peters, 1869 with tetrathyridia Mesocestoides lineatus (Goeze, 1782) in Ulan-Ude and the adjacent territory. A complete parasitological study of freshly caught specimens of the Mongolian racerunner was carried out according to generally accepted methods. Mongolian racerunners were caught at 4 sites: 1) Silicatny industrial settlement in Ulan-Ude; 2) a village on the southwestern perimeter of Ulan-Ude; 3) a village 22 km south of Ulan-Ude; and 4) steppe agricultural land 28 km southwest of Ulan-Ude. Tetrathyridia M. lineatus was recorded in the Mongolian racerunner at one of these four sites, in the Silicatny settlement of UlanUde (the prevalence was 11.1%; the abundance was 6.28 spec.). Cestodes of the genus Mesocestoides have a complex three-host life cycle. The first intermediate hosts of the genus are arthropods (insects, ticks). The second intermediate hosts are amphibians, reptiles, birds and small mammals. The definitive hosts of the Mesocestoides are carnivorous mammals, mainly foxes, dogs and cats. M. lineatus is circulating in the industrial village on the outskirts of Ulan-Ude and is the causative agent of mesocestoidiasis of carnivores, with the participation of the Mongolian racerunner, that performs the functions of the second intermediate host of this cestode. The detection of the cestode M. lineatus in urban areas only is due to the fact that animals accompanying humans participate in the life cycle of this helminth.

The results of many years of research revealed that in the conditions of the Udmurt Republic, in the soil on the territory of the ground runs of livestock enterprises, eggs of nematodes of the suborders Trichocephalata, Strongylata and Rhabdidata, and Eimeria oocysts were found. At the same time, Eimeria oocysts were stationary dominant in terms of quantity per 1 gram of soil (on average, from 204.4±13.9 to 267.4±15.7 pieces). Of the eggs of helminths, exogenous stages of representatives of the suborder Strongylata spp. were most often found, on average 166.1±9.2. In order to assess the effectiveness of soil disinfection on the ground runs, a hot solution of sodium hydroxide (caustic soda) was studied at a 5% concentration at a rate of 1 L/m2 with a 6-hour exposure and a Ligrocid at a 0.25% concentration at a rate of 0.25 L/m2 with 20-min. exposure. The results of our studies showed that when using Ligrocide, the intense-effectiveness of treatment against exogenous stages of helminths from the suborders Strongylata and Rhabdidata was 100%. However, despite its high efficiency, a single treatment does not completely destroy whipworm eggs and Eimeria oocysts. The degree of soil contamination with these parasites remains at the level of 5.6–16.8%. It was found that the soil disinfection on the ground runs of livestock enterprises with 5% sodium hydroxide was ineffective both against protozoan oocysts (intense-effectiveness, 65.6%) and nematode eggs (intense-effectiveness from 20 to 77.8%).
