Москвы. Помимо традиционных исследований почвы, нами были проведены копроскопические анализы обезличенных проб фекалий собак, собранных с поверхности почвы в весенний период после таяния снега.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Было отобрано 83 объединенные пробы почвы в 9 административных округах г. Москвы методом конверта на глубине до 10 см. Все пробы исследовали в четырех повторностях методом Романенко согласно МУК 4.2.2661-10 «Методы санитарно-паразитологических исследований». С тех же территорий, где отбиралась почва, было отобрано 365 обезличенных проб фекалий собак. Фекалии исследовали комбинированным флотационным методом. Пробы почвы и фекалий отбирали весной 2023 г. в период положительных температур сразу после таяния снега. Микроскопию проводили на микроскопе Motic BA410T с фотофиксацией. Идентификация обнаруженных объектов была проведена на основании морфометрических данных. Видовую дифференциацию яиц Toxocara canis и T. cati выполняли по отличиям в размерах яиц и строению наружной оболочки.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Городская почва контаминирована возбудителями паразитарных болезней в 9,3 % проб. Обнаружены яйца токсокар (5,7 %), из них T. canis в 3,9% проб, а T. cati в 1,8 % проб. Яйца Capillaria sp. выявлены в 1,5%, яйца Trichuris sp. в 0,9%. Яйца Hymenolepis sp. и ооцисты кокцидий выявлены в 0,6% проб. В фекалиях собак возбудители паразитарных болезней выявлены в 3,3% проб. Токсокары обнаружены в 1,4% проб, цисты изоспор в 0,8%, саркоцисты в 0,8%, яйца Toxascaris leonina в 0,3%. Яйца Toxocara sp. превалируют по частоте обнаружения в почве; преимущественно это жизнеспособные яйца с личинками. Это согласуется с данными, что в обезличенных фекалиях собак яйца T. canis регистрируют чаще. Яйца Trichuris sp. и Capillaria sp. обнаружены в почве со сформированными жизнеспособными личинками. Полученные данные показывают потенциал городских почв как фактора передачи паразитов для человека и восприимчивых животных, а собаки играют ведущую роль в контаминации городской почвы яйцами токсокар.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purpose of the research is to conduct a sanitary and parasitological examination of soil biotopes on the territory of Moscow. In addition to traditional soil studies, we conducted coproscopic analyzes of samples of dog feces collected from the soil surface in Spring.</p><sec><title>Materials and methods</title><p>Materials and methods. 83 combined soil samples were taken in 9 administrative districts of Moscow using the envelope method at a depth of up to 10 cm. From each combined sample, 4 samples were taken and examined using the Romanenko method according to MUK 4.2.2661-10 “Methods of sanitary and parasitological research”. From the same areas where soil was collected, 365 dog fecal samples were collected. Feces were studied using a combined flotation method. Soil and fecal samples were taken in Spring of 2023 during a period of positive temperatures immediately after the snow melted. Microscopy was performed using a Motic BA410T microscope. Identification of the detected objects was carried out on the basis of morphometric data. Species differentiation of Toxocara canis and T. cati eggs was carried out based on differences in the size of the eggs and the structure of the outer shell.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The city's soil is contaminated with pathogens of parasitic diseases in 9.3% of samples. Toxocara eggs were found (5.7%), of which T. canis in 3.9% of samples, and T. cati in 1.8% of samples. Eggs of Capillaria sp. detected in 1.5%, eggs of Trichuris sp. at 0.9%. Eggs of Hymenolepis sp. and coccidia were detected in 0.6% of samples. In dog feces, pathogens of parasitic diseases were detected in 3.3% of samples. Toxocara sp. eggs were found in 1.4% of samples, isospores in 0.8%, sarcocystis in 0.8%, Toxascaris leonina eggs in 0.3%. Toxocara sp. eggs are the leaders in the frequency of detection in the soil; these are mainly viable eggs with larvae. This is consistent with the data that T. canis eggs are most often recorded in anonymized dog feces. Eggs of Trichuris sp. and Capillaria sp. found in soil with formed viable larvae. The findings show the potential of urban soils as a parasite transmission factor for humans and susceptible animals, and dogs play a leading role in the contamination of urban soils with Toxocara sp. eggs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>анитарно-паразитологическое обследование</kwd><kwd>паразиты</kwd><kwd>зоонозы</kwd><kwd>городская почва</kwd><kwd>фекалии</kwd><kwd>собаки</kwd><kwd>Toxocara sp.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sanitary and parasitological examination</kwd><kwd>parasites</kwd><kwd>zoonoses</kwd><kwd>soil</kwd><kwd>feces</kwd><kwd>dogs</kwd><kwd>Toxocara sp.</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках Программы фундаментальных научных исследований в Российской Федерации на долгосрочный период (2021–2030 гг.), составляющей основу государственного задания № FGUG-2022-0012 без привлечения дополнительных источников финансирования.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of state assignment No. FGUG-2022-0012 without attracting additional sources of funding.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Горячева Р.
