Sanitary parasitological study of the contamination of environmental objects as factors of parasitosis transmission is an important element of sanitary and hygienic monitoring. Using sanitary-parasitological methods of research of environmental objects in 2018, wastewater and its sediments, soil and water of open surface water bodies as the main factors of parasitosis transmission were studied in the territory of the Rostov region and the Republic of Adygea. Screening works were carried out to indicate 137 objects of the surrounding environment that the parasitosis pathogens infected. Extensive and intensive indicators of the contamination of objects with the ascertained viability of the identified parasitic pathogens were determined. Wastewater and its sediments turned out to be the most epidemiologically significant objects, as evidenced by the level of contamination of these substrates with parasitic pathogens and to a greater degree the share of viable helminth eggs detected among them. The spectrum of parasitic pathogens detected in both territories in sewage and sediments was as follows: tokocar eggs (more than 50%), ascaris eggs, pinworms, taeniid oncospheres, ankylostomid eggs, dicrocelium, diphyllobotriid. The soil remains one of the main components of the environment, of great importance in the spread of parasitic invasions. In the studied areas, the ovogram of detected parasitic pathogens in the soil was almost identical: eggs of ascaris, tokocar, pinworms, etc. In addition, the maximum epidemiological significance of the soil was established for geo-and contact helminth infections in respect of the territories of residential areas of settlements, pre-school institutions. The investigated water samples of open surface reservoirs contained only non-viable helminth eggs with low contamination intensity (1–2 specimens / 25 l.).

Ascariasis is a significant public health problem. More than a quarter of the world's population is at risk of infection with soil-borne parasites, and Ascaris lumbricoides is the main type of geohelminthiasis that infects people and affects the population of all countries to some extent. The study is aimed at monitoring ascariasis in the South of Russia, including determining a risk of infecting the population. The analysis of the incidence of ascariasis was performed based on official statistics "On the incidence of protozoans and helminthiasis in the population of the Russian Federation". Over the past 5 years, a serological screening of 2600 samples of blood serum of conditionally healthy residents of the South of Russia was conducted at the premises of the Rostov Scientific Research Institute of Microbiology and Parasitology of the Rospotrebnadzor. Over the same period, more than 7,500 parasitological studies of environmental objects (waste water and its sediments, soil, sand, and surface water) were conducted. A significant proportion of seropositive individuals, as well as the evidence of ascarid eggs detected in environmental objects indicate that the potential risk of infection of the South of Russia population with ascariasis remains. Additionally, the obtained results indicate the need to continue monitoring ascariasis. Further research will provide a more complete picture of the current epidemiological situation on ascariasis and its spread in the South of Russia.

We analyzed data reflected in the records of the epidemiological screening of cases with echinococcosis in 2019 in some constituent entities of the Russian Federation. It was noted that both rural people and urban residents suffered from the disease equally, while women suffered a little more than men (54.4%). It is found that the most common localization of echinococcal cysts, both in men and women, is the liver (79.5%), and the lesion of the lungs caused by echinococcal cysts (9.1) is in the second place. We presented multiple localization of echinococcal cysts affecting several organs simultaneously to a lesser extent. Two cases of hydatidosis and two cases of multilocular hydatid cyst in the liver were accompanied by a fatal outcome. In some territories, alveococcosis was diagnosed in 14 (8.75%) cases. Contacts with dogs, work on livestock farms, caring for pets, picking wild berries or mushrooms in the forest and eating them without thermal treatment, use of raw river water in housekeeping, eating unwashed vegetables and berries, activities in natural environment, hunting and dressing of wild animals, or failure to observe the rules of personal hygiene have great importance in the spread of this disease among the population, according to epidemiological records.

Аннотация В статье рассматривается одно из организационно-педагогических условий повышения качества подготовки учащихся к ЕГЭ на основе взаимодействия вуза со школами: обоснована актуальность его введения, описаны виды, тактики и формы педагогической поддержки. Педагогическая поддержка учащегося при подготовке к ЕГЭ имеет свою стратегию, которая находит свое выражение в четырех тактиках, которые в совокупности представляют собой процесс развития способности учащихся быть субъектом собственной жизнедеятельности при подготовке к единому государственному экзамену. Ключевые слова: единый государственный экзамен, психологическое сопровождение, педагогическая поддержка, средняя школа.

Wide circulation of the causative agent of dirofilariasis in the natural environment and the lack of appropriate measures to identify and deworm infected animals – obligate definitive hosts (domestic dogs and cats) promotes infestation by the human helminth infections. The aim of the study is to analyze the incidence of dirofilariasis in people according to official statistics. The analysis of 52 surveillance maps collected for 2019, 2020 and official statistics on the incidence of parasitic diseases for 2019 was carried out. The analysis of the surveillance maps showed that dirofilariasis is most often registered in the south of Russia (the share of the Southern and Volga Federal Districts accounts for more than 50% of registered patients), the main group of patients with dirofilariasis falls on 30–39 year old people and older 60 years old or more (23.1%, respectively). The structure of patients with dirofilariasis is dominated by women (65.2%). Infestation is more often registered in urban residents (75%). Almost half of the removed dirofilaria, were localized in the head area (weight share of 44.2%). Among the removed helminths, females predominated (80.8%), of which 72.7% were immature. Cases of human infestation with dirofilariasis are registered throughout the Russian Federation, with the exception of the northern regions. Despite the increase in the proportion of Dirofilaria immitis, especially in the south of Russia, the disease caused by Dirofilaria repens and extremely rarely D. immitis are registered in people on the territory of the Russian Federation. It is possible that in this case there is a hypodiagnostic invasion of D. immitis.
