The main purpose of the work was to identify helminth and protozoan parasite infections and helminthozoonosis in domestic dogs of different age groups in Moscow. Coproovoscopic examinations were carried out during 2022 for dogs older than a year and puppies up to 6 months from 5 administrative districts of the City. Fecal samples were collected in defecation of dogs individually in a sterile container with the animal information on the label during dog walking by their owners. Infection of the dogs was found with the following zoonotic helminths: Toxocara canis, Toxascaris leonina, Dipylidium caninum, and Taenia spp.; and protozoa: Isospora canis. Toxocara canis reached its maximum value in the puppies up to 6 months of age with the prevalence of 33.3%, and in the dogs older than a year with the prevalence of 15.3%. Toxascaris leonina was not found in the puppies under 6 months of age; in the dogs older than a year, it reached the maximum invasion value with the prevalence of 9.5%. Dipylidium caninum reached the maximum invasion value in the puppies aged up to 6 months with the prevalence of 7.8%, but the dogs older than a year were not found to have Dipylidium caninum. Taenia spp., were found neither in the puppies nor in dogs older than a year.

On the territory of the slaughterhouse located in the Moscow Region, a veterinary and sanitary assessment of carcasses and internal organs was carried out in accordance with the Customs Union Technical Regulations "On the safety of meat and meat products" No. 68 TR CU 034/2013 dated 09/10/2013 for the infection with larval cestodiasis. As a result, 3 species of pathogens were recorded: Echinococcus granulosus, Cysticercus taenuicollis and Coenurus cerebralis. E. granulosus larvae was detected in the parenchymal organs in 211 cases, which corresponds to 42.2%. It is worth noting that the blister cavities were localized in the liver in 23.7%, in the lungs in 15.6%, and in both organs in 2.9%. From 1 to 8 blisters were found. In addition to echinococcosis, coenurus blister cavities were found in 2 animals, and Cysticercus tenuicollis, in 22 sheep from the Karachay-Cherkess Republic; the IP was 2.0 and 22.4%, and tenuicollic cysticercosis infection in the Astrakhan and Volgograd Regions was 2.9 and 6.0%, respectively. Such a wide spread of echinococcosis is a fairly high indicator for such a particularly dangerous zoonosis, as parenchymal organs can be a source of infection for dogs, and subsequently for humans.
在位于莫斯科州的屠宰场境内，根据2013年10月9日第68 TR CU 034/2013号关税同盟技术法规“关于肉类和肉类产品的安全”，对尸体和内脏进行了兽医和卫生评估，以确定是否感染幼虫囊虫病。结果共检出细粒棘球蚴、带状囊尾蚴和脑棘球蚴3种病原体。211例肺实质器官检出细粒绦虫幼虫，占42.2%。值得注意的是，23.7%的水疱空洞位于肝脏，15.6%位于肺部，2.9%位于两个器官。发现1 ~ 8个水泡。除棘球蚴病外，在2只动物中发现了棘球蚴水疱，在卡拉恰伊-切尔克斯共和国的22只羊中发现了细囊尾蚴;感染率分别为2.0和22.4%，阿斯特拉罕和伏尔加格勒地区的细粒囊尾蚴病感染率分别为2.9和6.0%。棘球蚴病的如此广泛传播是这种特别危险的人畜共患病的一个相当高的指标，因为实质器官可能是狗的感染源，随后是人类的感染源。

The ecosystems of the south-east of the Northern Caspian Sea are inhabited by three representatives of artiodactyls, namely, the Daghestani (East Caucasian) tur, the chamois (wild mountain goat) and the roe deer. All three species are under the state protection and listed in the Red Book. The helminth biodiversity in these three species of ruminants has been studied for 35 years due to the fact that the hunting is prohibited, therefore it is very difficult to collect material for research. The collected material analysis showed that helminth biodiversity in the Daghestani tur was represented by 20 species, chamois by 16 species, and roe deer by 15 species. From the trematode and cestode classes, 2 species of F. hepatica, D. lanceatum, M. expansa, and M. benedeni were recorded. The rest of the fauna was represented by nematodes including 22 species from the suborder Strongylata, one species of G. pulchrum from Spirurata and one species of T. ovis from Trichocephalata. The invasion prevalence (IP) of helminths in the Daghestani tur varied from 3.5 to 14.2% with the invasion intensity (II) of 1–12 specimens, respectively, in the chamois up to 8.3% and 2–5 specimens, and in the roe deer 4.1–8.3% and 1–4 specimens. The largest number of species were represented by the genera Nematodirus, Ostertagia, and Trichostrongylus.

Our research is devoted to the study at the present stage of the species composition and distribution of blood-sucking dipteran insects, carriers of dangerous parasitic zoonoses in the Meghri District of the Syunik Region, the Republic of Armenia. The studies were carried out from June 25 to December 3, 2022 in the Meghri District of the Syunik Region (altitude 394–565 m above sea level, semi-desert zone) along the Armenian-Iranian border, since it is here that invasive species are most likely to enter Armenia. For the first time in Armenia, automatic light Mothmatic Freezer Traps, and high-tech automated traps for collecting nocturnal entomofauna combined with a freezer were used as equipment for collecting nocturnal insects with positive results. Based on our research, it was established that the fauna of nocturnal bloodsucking Diptera in the Meghri District was quite diverse and was represented by 9 midge species: Culex pipiens, Cx. quinquefasciatus, Culiseta annulata, Aedes caspius, Ae. vexans, Ae. geniculatus, Anopheles maculipennis, An. claviger, An. hyrcanus and 3 mosquito species: Phlebotomus papatasi, Ph. kandelakii and Ph. sergenti.

Within the section of general helminthology, based on the diversity analysis of biological cycles of helminth development, and the objective availability of common algorithms in closely related species, a conceptual proposal has been developed to introduce a new stylized category, the Helminth Developmental Biology Formula (DBF), into theory and scientific practice. The new category, the DBF, is designed for a logically sound, stylized and concise presentation of essential elements of bioecological characteristics of helminths. Basic regulations for the formation of the formula structure have been developed. A number of indicative parameters are proposed which, in accordance with helminthological terminology and pictograms, form the informational basis of the helminth DBF category. The regulation algorithm is universal, and, taking into account the bioecology characteristics of helminths, it is applicable to the DBF formation for representatives from various zoological taxa. On the example of biological cycles of development of trematode Paramphistomum daubneyi Dinnik, 1962, cestode Spirometra erinacei-europaei (Rudolphi, 1819), nematode Avioserpens mosgovoyi Suprjaga, 1965, Acanthocephala Macracanthorhynchus hirudinaceus (Pallas, 1781), and Monogenea Diplozoon paradoxum Nordman, 1832, in a stylized format, the structure and information content of the category Helminth Developmental Biology Formula are presented. The field of practical use of the helminth DBF is the following: 1) scientific and methodological, educational and reference helminthological literature, as an additional subheading within the main Helminth Developmental Biology Section; 2) in computer databases of various thematic orientation, in scientific characterization of the main bioecological parameters of helminths, due to the need to present material in a concise format.

Significant economic damage is annually caused to agriculture by parasitic diseases of livestock animals. It is necessary to regular monitor the spread of endoparasites in small cattle on the territory of various subjects of the Russian Federation in order to subsequently improve control measures and ongoing therapeutic and preventive measures, as well as to detect resistance in various helminth species and genera to active ingredients of modern anthelmintics used. Research was carried out to study the endoparasite fauna of small cattle on the peasant farm and private subsidiary plots of the Podolsk, Voskresensk and Ramensk city districts of the Moscow Region. Feces were taken individually from each animal: 50 sheep, and goats (24 lactating goats and 9 baby goats kept together). Based on the studies, it was found that the sheep were infected with pathogens of gastrointestinal nematode infections as follows: 76% of the suborder Strongylata; 26%, the genus Nematodirus; 4%, the genus Trichocephalus spp.; 62%, protozoa of the genus Eimeria, and the milking and young goats by 87.8% pathogens of the suborder Strongylata and protozoa from the genus Eimeria (EI = 15.2%), which indicates a high infection rate of these pathogens in small cattle.

Soil, bottom sediments, and sewage sludge are the main sources of infection of humans and animals with helminth eggs, and protozoan cysts and oocysts. For the disinfection of environmental objects, chemical disinfectants are successfully used. To identify the most effective disinfection means for soil and environmental objects, laboratory studies of the ovicidal activity of disinfectants are carried out on soil samples. Currently, laboratory practice has no standard methods available for determining the ovicidal efficacy of disinfectants in the soil. A device is offered for the experimental selection of disinfectants for disinfecting soil, geologic material, sewage sludge or bottom sediments contaminated with helminth eggs, and protozoan cysts and oocysts. The laboratory device is a three-segment steel column in the form of a cylinder with supports provided at the base, and a cover with a foam outlet and a filler neck located on the upper part, and a storage tank for collecting the spent disinfectant solution located in the lower part. The cylinder is filled with soil segment by segment, and microcontainers with bioagent are placed at the bottom of each segment. The soil is poured with a disinfectant; and the microcontainers are removed from the soil after various exposure periods to determine the ovicidal activity of the disinfectant.

Pruritic dermatosis is chronic persistent processes. The principal symptom is tormenting itchy sensation excruciating for patients affected. Medical treatment is often ineffective. Itchy skin may be caused by parasite invasions. Whether external or endogenic, they are highly toxic, which is important in pathogenesis. Therefore, it is necessary to exclude parasitosis in patients with itchy skin. Intoxications and allergic reactions caused by polypragmasy are also capable to cause itching. In total, 64 patients were examined. They underwent histocoprological analysis for helminthic infections. Of them, 41 patients were found to have mono- and polyinvasions and abnormal intestinal macro- and microbiome, which required specific therapy. In 13 patients, the cause was polypharmacotherapy. General cryogenic therapy was applied in 12 patients with generalized itching. Exposure of skin parasites to extreme law temperatures discontinues their life cycle. The effects of general cryogenic treatment result in itching elimination, reduced inflammation, pain attenuation and wound healing. The skin is an informative organ showing therapeutic efficacy when properly treated. Application of general cryogenic treatment as an etiologically focused method is especially prescribed against external parasite infections (such as scabies, dirofilariasis, Morgellons disease).

One of the promising high-tech systems for the use of agricultural chemistry can be the development of original forms of agrochemical preparations (fertilizers and pesticides) of prolonged action. The slow-release polymeric composites formed by our technology have a number of advantages. A single injection of preparations during seeding allows avoiding multiple medical top dressings (for fertilizers) and treatments (for pesticides) during the growing season. The most important principle of the effectiveness of using agricultural chemistry is the linking of the timing of top dressings and treatments to the developmental phenophases of both plants and parasites. Much depends on the characteristics of the development of parasites. For example, larvae of cyst-forming nematodes are vulnerable to drugs during migration in soil. However, the cyst-forming nematode of potato develops in one generation for a season, and the cyst-forming nematode of beet develops in 3–4 generations. In the latter case, additional use of modified forms of nematicides is possible. In favor of drugs with prolonged action (apart from a multiple increase in economic efficiency, especially in the event of a shortage of the drug), we should attribute the technological possibility we have worked out to program the action of drugs. We have adopted the following reference terms for prolongation, 1, 3 and 6 months. Technologically, this is achieved by the polymer concentration in the composite. In this case, our method can be used to take into account weather risks.

The most well-known ectoparasites of dogs and cats are fleas and Acariformes, which are also carriers of infectious and invasive diseases. Animals admitted to the veterinary clinic served as the material for the research. The study involved 3346 animals, of which 1596 cats and 1707 dogs. Classical life-time diagnostic methods of ectoparasitosis were used. The results obtained show that among all dermatological patients, the proportion of those infected with ectoparasites was 47.6%. Among ectoparasites, fleas were most often recorded; the prevalence of infection was 4.78%. Aphanipterosis was recorded in all seasons of the year, the maximum invasion of 1.76% was observed in autumn, and the minimum of 1.30% in winter. The second most common disease was otodectosis (IP 1.94%). The heyletiellosis rate was 0.27% (total 9 animals, including 1 cat); and demodicosis, 0.24%. Notoedrosis was only diagnosed in the cats with IP 0.15%, sarcoptosis was recorded in the dogs with IP 0.09%. Ectoparasite infections are recorded at any time of the year, however, the peak of invasion occurs to a greater extent in the summer-autumn months. They can also occur at any age, but are more common in cats and dogs under one year of age.
