The existing interest in the problem of toxoplasmosis is largely due to the fact that Toxoplasma gondii plays a significant role in human pathology. Toxoplasmas enter the human body in many ways: through the mouth when eating raw meat; with contaminated products, vegetables or fruits; with dirty hands, after contact with infected animals; through damaged skin, mucous membranes, when removing skins from infected animals or dividing carcasses; in medical procedures in patients with toxoplasmosis; and prenatally, from mother to fetus. Toxoplasmosis is more common in children, while adults may remain asymptomatic carriers of the pathogen. The reliability of invasion in humans is only established by the detection of toxoplasma in the blood, sputum, cerebrospinal fluid, puncture samples of lymph nodes, remnants of fetal membranes, placenta, etc. Therefore, the purpose of our study is to determine the occurrence of toxoplasmosis in the Krasnodar Territory for 5 years (2018–2022) and to identify organ systems that are affected most often. Toxoplasmosis is widespread in the Krasnodar Territory. This is due to climatic and geographical features. The study used data from outpatient medical records of people with diagnosed toxoplasmosis who seek medical advice in infectious diseases hospitals of the Krasnodar Territory.

Infection of plants with nematodes is still one of the main limitations of crop productivity. The research material is the infected rhizosphere and the roots of various plant crops collected on farms and personal subsidiary plots of the Tashkent Oasis. Four species of Meloidogyne Goeldi, 1887 were found in the study area in the Tashkent Oasis: M. arenaria, M. javanica, M. incognita, and M. hapla. It was established that infection of plants with nematodes depended on the characteristics of plant resistance, as well as soil and climatic conditions of the study region. However, the degree of occurrence of individual species on plants varied significantly. In terms of distribution of nematode species in the closed soil conditions of the Tashkent Oasis by districts and cities, M. arenaria was determined to be the most common species, whereas the least common species was M. javanica. The highest infection with nematodes of the genus Meloidogyne in the districts of the Tashkent Region was 64.0% on personal subsidiary farms of the Yangiyul District, and the lowest infection was 12.5% on personal subsidiary farms of the Buka District. M. arenaria is the most common species in the Tashkent Oasis, and M. javanica is the least common species. M. arenaria and M. incognita are dominating species, M. hapla is common, and M. javanica is rare.

This paper presents the results of the analysis of official reporting data on the incidence of echinococcosis for the last 5 years (2017–2021) and the analysis results of maps of the epidemiological survey of echinococcosis foci in the Russian Federation for the same period. During 2020–2021, a significant decrease in incidence rates for cystic echinococcosis was recorded, as well as in the total number of detected parasitic diseases almost in 1.8 compared to 2018, which is evidently due the limited availability of routine medical care to patients during the pandemic of the new coronavirus disease, COVID-19. But it should be noted that the incidence of alveococcosis remained at the same level over the last 5 years. Rural residents of working age suffer from echinococcosis more often. Despite significant improvements in the methods of instrumental diagnosis of echinococcosis and increased availability of high-tech medical care, echinococcosis-associated lethal outcomes are recorded annually in the Russian Federation. The lethality rate of cystic echinococcosis varied from 0 to 1.1% for the last 5 years, and alveococcosis, from 2.0% to 6.25%.

The purpose of this work was to clarify the species composition of acanthocephalans of Baikal waterbirds and to determine their relative abundance in modern environmental conditions. Ninety nine specimens of 13 species of waterfowls were studied by the method of special and complete dissection in Lake Baikal. Birds were studied according to the method given in the work by M. N. Dubinina. Three species of acanthocephalans were recorded: Polymorphus minutus (Goeze, 1782), P. acutis Van Cleave et Starret, 1940, and P. magnus Skrjabin, 1913. To assess the quantitative parameters of host infection, the following indices were used: prevalence of invasion (iP), intensity of invasion (iI, limits) and abundance (A). P. minutus was the most widespread species of acanthocephalans. Acanthocephalans are localized in the small intestine of birds. Polymorphae penetrate very deeply into the small intestine wall of the host. Unlike echinorhynchids whose proboscis penetrates only into the submucosa of the intestinal mucosa of fish, the proboscis and neck of polymorphids pierce the mucous and muscular membranes reaching the serous membrane. Tubercles are observed on the outer, serous side of the intestine that mark places of attached acanthocephalans. With a high number of definitive hosts, they can potentially exert a regulatory influence on the number of bird populations.
本研究的目的是阐明贝加尔湖水鸟棘头目的种类组成，并确定其在现代环境条件下的相对丰度。对贝加尔湖的13种水禽进行了全面解剖，共99种标本。根据M. N. Dubinina工作中给出的方法对鸟类进行了研究。棘头类有3种:Polymorphus minutus (Goeze, 1782)， P. acutis Van Cleave et Starret, 1940, P. magnus Skrjabin, 1913。采用入侵流行度(患病率)、入侵强度(极限)和丰度(A)等指标评价宿主感染的定量参数。棘头类动物局限于鸟类的小肠。多态菌深入宿主的小肠壁。与棘吻鱼不同，棘吻鱼的喙只穿过鱼肠粘膜的粘膜下层，多形鱼的喙和颈穿过粘膜和肌肉膜到达浆膜。在肠的外侧浆液面可见结节，标志着附着的棘头体。由于具有大量的最终宿主，它们可能对鸟类种群的数量施加调节影响。

The efficacy of a commercial insecticidal preparation based on Paecilomyces fumosorosea, Pecilomycin PM116, against root-knot nematode (Meloidogyne arenaria) was evaluated on tomatoes. A comparison was made with biological (Nematophagin) and chemical (Vydate 5G) nematicides. Pecilomycin and Nematophagin did not suppress the development of plants, their weight and size were at the level of healthy controls. The analysis of photosynthetic pigments showed that the chlorophyll b level, the sum of chlorophylls and carotenoids when the root system was treated with Pecilomycin was comparable to healthy controls. Despite the fact that the plants treated with Pecilomycin were completely infected, their infection rate was 1.27 times lower than the controls, and single galls were only present on the roots. The treatment of the roots with Pecilomycin did not significantly affect the number and size of galls; the females in them were at the control level; however, the number of eggs in oothecae was 1.5 times less. Thus, Pecilomycin has an inhibitory effect on the root-knot nematode and a beneficial effect on the tomato plant. Further research and search for new strains of P. fumosorosea with high virulence against one or more pests opens up opportunities for the creation of new bionematicides.

Toxoplasmosis occupies one of the first places in the world among all foodborne parasitic diseases, since it is recorded on all continents and can affect many species of mammals and birds. The causative agent of toxoplasmosis, Toxoplasma gondii, is the obligate zoonotic parasite that can be transmitted from animals to humans. The main sources of infection are soil contaminated with cat feces, poorly thermally processed meat, and transplacental route of transmission. There is scanty data available in Armenia to assess the role of livestock animals as a source of alimentary toxoplasmosis in humans. In this regard, the purpose of this work was to conduct a pilot study on the identification of seroprevalence in some livestock animals using the Tavush Region of Armenia as an example. An ELISA was used to screen 241 samples for the detection of total T. gondii antibodies in blood serum. As a result, 42 (17.4%) of all tested samples reacted positively including 23 (39%) samples from small cattle, 4 (28.6%) from pigs, and 15 (8.9%) from cattle. Thus, our data correlate with the data of a number of foreign authors with the prevailing proportion of seropositive sheep and pigs. To obtain a complete picture of toxoplasmosis among livestock animals, research in this direction should be continued.

The article provides information on the harmful effect of horseflies (Diptera, Tabanidae) as a midge component and a vector (carrier) transmitting pathogens of infectious and parasitic diseases including zoonosis. Horseflies are harmful to animals and humans in places of their abundance. Horseflies cause significant economic losses to livestock. With an intense attack of horseflies, individual areas of the skin of animals represent a continuous bleeding surface. Horsefly saliva inserted into a wound at the time of the bite is very toxic and allergenic causing a local inflammatory process and general intoxication of the body. The insects are of particular danger as vectors transmitting pathogens of animals and humans. The role of horseflies in the transmission of tularemia in natural foci of this infection has been proven. The sources of horsefly infection are primarily various small mammals including water rats. Horseflies are equally important as carriers of the anthrax pathogen. Causative agents of Coxiella burnetti infection, blackleg, pasteurellosis, and other infections have been isolated from horseflies. Horseflies are involved in the transmission of Trypanosoma evansi in horses and camels, anaplasmosis in cattle, Theileria cervi in reindeer, and equine infectious anemia virus.

The effect of the tested substances on in vitro nematicidity and nematostaticity was verified on saprobiotic (Caenorhabditis elegans, Turbatrix aceti) and phytoparasitic nematodes (Ditylenchus destructor). Working solutions were prepared in the following dilutions: 1) 1/1000, 2) 1/100, 3) 1/10, 4) 1/1, 5) undiluted, 6) control, water, and 7) standard (horseradish root juice). The solution of above concentrations was introduced into the plate wells of 0.5 mL in 4 repetitions, then a well-mixed nematode suspension of 0.5 mL was added with 50±10 nematodes in average. After 24 hours of hold-times, mobile and immobile nematodes were counted, then after 48 hours nematodes were counted again. At the end of the experiment, nematodes were washed from the drug in order to determine the nematostatic effect. In vitro screening showed that the horseradish root juice, black nightshade berry juice, and red nightshade leaf and berry juice had nematicidal properties. The nematostatic effect was recorded in shoots of the green tuber, tissues of the green surface of the tuber and tuber juices, juice of red nightshade leaves, and juice of black nightshade leaves and berries.

The purpose of this work is to study the spread and species composition of pathogens of trematode infections among cattle in North-Western and Southern Uzbekistan. The studies were carried out on the territory of the Republic of Karakalpakstan, Khorezm and Kashkadarya Regions in 2020–2023. Helminthological material was collected in all seasons of the year. In total, 364 heads of cattle were examined by complete and partial helminthological dissections. As a result of the studies carried out in the northwestern and southern regions of Uzbekistan, 9 trematode species belonging to 7 genera, 5 families and 4 orders of the class Trematoda were recorded. In the northwestern region, 175 heads of cattle (65.3%) out of 268 examined animals were infected with certain trematode species. Of those infected, 124 had associative invasions, and 51 had monoinvasions. In the southern regions, 41 animals (43.2%) out of 96 examined animals were infected with trematodes. Of the infected animals, 27 (65.8%) were infected with mixed trematode infections, and 14 (34.1%), with monoinvasions. Of 9 trematode species under consideration with natural and synanthropic focality, Schistosoma, Fasciola, and Dicrocelium were recorded.

The purpose of the research is to compare diagnostic and design characteristics of Gastros and AVT-L devices in order to determine the prospects for improving the veterinary and sanitary examination of carcasses with trichinellosis. Taking into account the requirements for ensuring the safety of food products, in particular meat and meat products, special requirements are imposed on the quality of trichinelloscopic control in the conditions of veterinary diagnostic laboratories of meat processing enterprises, markets and slaughterhouses. For this purpose, a fairly wide range of devices is used for both compressor trichinelloscopy and peptolysis of muscle tissue. Comparative tests were carried out for Gastros of Petrolaser LLC and AVT-L (VNIIP) type devices used for this purpose. In the process of work, we analyzed the features of the examination technology, the structural elements of the devices and the diagnostic efficiency. In general, the devices met the requirements of the veterinary and sanitary examination for trichinellosis in various production conditions, however, their design for manufacturability had significant differences. With equal diagnostic efficiency, the devices have significant design differences regarding the type of thermal stabilization, automation, control systems for the duration of the peptolysis and settling of the medium, and the dimensions of the devices. According to these parameters, Gastros is more promising at the present time. AVT-L requires some improvements.
