“…were isolated from the environment, which in turn area rather dangerous factor for health of people (Nejsum et al, 2005). Also, to the abovementioned, we should add that eggs of helminths are rather resistant to negative environmental factors, which in turn conditions their constant circulation in the environment (Gaspard et al, 1995;Capizzi-Banas et al, 2004), and change in their resistance properties (Boyko & Brygadyrenko, 2017).…”

The large number of species which cause parasitic infestations and the wide variety of routes and factors of their transmission give great relevance to systematic veterinary-sanitary research into environmental objects, necessarily paying attention to local natural-climatic conditions, social structure and the activities of the population. This problem is most often studied by medical researchers and ecologists, and the extent of studies on this topic from a veterinary-sanitary point of view is insufficient, which conditioned our choice of the current scientific study. Our goal was determining the level of contamination of urbanized territories with exogenous forms of helminths. The research was conducted during 2010–2018 in the territory of Kharkiv Oblast of Ukraine. During the study, we examined 41 samples of soil, extracted both in rural areas, and in urban conditions, and also 100 samples of feces of animals and birds. During the examination of soil from rural areas in Kharkiv Oblast and soil in Kharkiv and Balakleia, we found that it was contaminated with eggs of helminths of different morphotypes. It was determined that mean level of contamination of soil in rural area equaled 12.5%. At the same time, the level of contamination of soil of river banks was 15% at intensity of 52 ± 5 eggs/kg of soil and 10.0% in meadows at intensity of 54 ± 8 eggs/kg of soil. The level of contamination of the soil of park zones of urbanized territories with exogenous stages of helminths was 5–55% and that of residential zones of cities was 20.0–23.3%. In general, in the samples of soil, eggs of Strongilata, Ascaridata, Trichocephalus and Cestoda were isolated, and in the soil of rural areas also eggs of Trematoda class. It was proved that cattle and small ruminants discharge feces into the environment which have highest number of eggs of Strongylata spp. helminths (285 ± 3 eggs/g of feces). Excrement of infested birds contaminate the environment with exogenous forms of helminths of Trichocephalata (Capillaria spp.) suborder (101 ± 7 eggs/g of feces). In cities, dogs and cats, infested with helminths, discharge into the environment feces with eggs of parasites that belong to Toxocara spp. (75 ± 4 eggs/g) and Dipylidium caninum (6 ± 1 eggs/g). Droppings of infested birds contaminate the environment with exogenous forms of helminthes of Strongylata spp. (57 ± 2 eggs/g), Аscaridia spp. (19 ± 4 eggs/g) and Capillaria spp. (11 ± 2 eggs/g).

“…The presence of exogenous forms of helminths in environmental objects worsens its veterinary-sanitary condition, and in some cases pose infestation threat to humans. Therefore, it is important to carry out integrated anti-parasitic measures in livestock biocenoses (Eysker & Ploeger, 2000;Charlier et al, 2014;Boyko & Brygadyrenko, 2017).…”

Today, one of the important problems in the cultivation and maintenance of agricultural and domestic animals, both in industrial and private farms, is the spread of ecto- and endoparasites, which cause a significant decline in animal productivity, endanger their health and cause economic losses. The study of the level of distribution and conducting of diagnostic studies on parasitoses of animals in farms with different production orientation is an important and integral part of the overall complex of preventive and health-improving measures. The research was carried out during 2007–2017 in livestock enterprises of Kharkiv Oblast. As a part of the research work, 540 samples were collected from livestock farms, of which 180 were from the premises for keeping pigs, 100 from premises for keeping sheep, 120 from premises for keeping cattle, 80 from premises for dogs and 60 – from the surrounding territories of the livestock enterprises. We found that the objects of livestock rearing (pig complex, sheep farm, dairy farm, cynological center) in Kharkiv Oblast have a significant level of sanitary contamination with exogenous forms of helminths (21.7–45.6%) and the soil of the territories (20.0–36.6%). From samples taken from premises for pigs, eggs of four morphotypes were isolated (Ascaris suum – 5.3%, Trichuris suis – 14.6%, Oesophagostomum dentatum – 60.6%, Strongyloides ransomi – 19.4%), from premises for sheep – three morphotypes (Dicrocoelium lanceatum – 3.8%, Trichuris ovis – 29.3%, Strongylata spp. – 46.9%), from premises for cows – three morphotypes (Neoascaris vitulorum – 2.7%, Trichuris skrjabini – 12.9%, Strongylata spp. – 34.5%), premises for dogs – four morphotypes (Toxocara canis – 6.1%, Toxascaris leonina – 5.4%, Trichuris vulpis – 20.6%, Ancylostoma caninum – 17.5%). It should be noted that the places most contaminated with eggs of helminths were manure gutters (100%) and the floor of livestock buildings (50.0–86.7%). It has also been determined that, in the conditions of the cynological center, the Musca domestica was the source of environmental contamination with exogenous forms of Toxocara canis and Trichuris vulpis, and that the Muscina stabulans and Stomoxys calcitrans can be the source of spread of larvae of Ancylostoma caninum and eggs of Trichuris vulpis respectively.

“…), and also in construction, in goods for medicine (parts for blood transfusion system, Petri dishes, additional disposable instruments). In pure state these polymers are inert and non-toxic, but in the process of their production, harmful stabilizers, salts of heavy metals and other technical additives are used, which negatively affect the human organism of after being introduced to it (Halden, 2010;Lamontagne, 2012;Norh & Halden, 2013;Boyko & Brygadyrenko, 2017;Lieshchova et al, 2018). Apart from the problem of safety in the process of production, many chemical additives which provide needed properties for the produced goods also negatively affect the ecological situation and human health (Anon, 2007;Koch & Calafat, 2009).…”

Goods of plastic, due to their durability, universality and economical properties are broadly used in all spheres of life. On the whole, polymers are inert and nontoxic, but in the process of their production, various additives are used, which on contact or introduction into an organism has a negative effect on it. In our study, we determined the impact of some types of plastic (polyvinyl chloride, polysterene and polyethylene) on the organism of laboratory animals according to changes in their body weight, indices of mass of the internal organs, and blood parameters. For the experiment, we formed four groups of white male mice at the age of 3 weeks and average body weight of 50 g. For each group, we used different litter. For group I, the litter was sawdust; and for the other groups we added plastic products in different volumes to the sawdust; for group II finely cut polyvinyl chloride, for group III cut polyethylene, and for group IV granules of polystyrene. Every 3 days, we determined the body weight of the animals, and 32 days later we determined mass of the organs, clinical and biochemical parameters of the blood. Addition of polyvinyl chloride, polyethylene, and polystyrene into the substrate for mice did not have a significant effect on tempi of growth of body weight, and also relative mass of heart and lungs. Polyvinyl chloride and polystyrene have an immune-suppressive effect, and polyvinyl chloride affects both central and peripheral organs, and polystyrene mostly harms the peripheral organs. All used types of plastic cause leukocytopenia, following which neutrophilia of band neutrophils and monocytosis takes place as a result of damage to the biological barriers. We determined the systemic toxic effect of the studied types of plastic on the internal organs, which manifested in increase in their mass (liver, kidneys), steep increase in the activity of liver enzymes (AST, ALT), simultaneous decrease in activity of alkaline phosphatase and content of cholysterol and glucose in the blood serum of the mice. Also polyvinyl chlorine, polyethylene and polystyrene cause degeneration of the epithelium of the uriniferous tubule, which is manifested in reduction of globulins and creatinine in the blood of animals from the experimental groups following increase in relative mass of the kidneys. The results of our research allow us to state that different types of plastic can cause toxic effect on animals, as well as people who are in frequent contact with them.
