Dispersion and circulation of parasitosis pathogens in the environment

  1. ANTHROPOGENIC EFFECTS ON THE ENVIRONMENT, CONDITIONS OF CIRCULATION IN IT Causative agents of parasitosis and the spread of invasions
    Various forms of human influence on the environment can lead to an improvement or worsening of the conditions of circulation of pathogens of parasitic diseases in it. This, in turn, will contribute to reducing the epidemiological significance of foci of individual parasitoses up to their complete disappearance; strengthening the epidemiological potential of focal territories, and therefore, increasing
  2. ENVIRONMENTAL ACTIVITIES FROM PARASITOSIS PATTERNS
    In the prevention of invasive diseases, regardless of the mechanism of infection and transmission pathogens, it is necessary to take into account not only their biological characteristics, but also the influence of certain social conditions in which the epidemic process develops. This position is especially clearly confirmed in intestinal parasitoses (helminthiases, protozoa), when the role of sanitary-hygienic
  3. The main ways of the circulation of helminth eggs in the environment
    The soil. The ingress of helminth larvae, intestinal protozoa cysts from sewage (feces) into the soil (Fig. 13) occurs in the absence of latrines, their arrangement at a far distance from housing and work places, when they are unsanitary, and used as fertilizer in gardens, gardens, when emptying night pots in the courtyards (at the porch), the commission of the act
  4. Methodological foundations of the study of the relationship of the incidence of parasitosis with contamination of their pathogens
    The health status of the population is the main forming factor in the system of human sciences and the main criterion for assessing the quality of the environment. Assessment of the environmental impact on the spread of intestinal parasitosis is one of the essential components of a comprehensive analysis of the relationship of environmental factors and living conditions of the population with their state of health. Based on own results
  5. Development and resistance of parasitosis pathogens in various environmental conditions
    Development and resistance of parasitosis pathogens in various environmental conditions
  6. Quantitative epidemiological significance of indicators of pollution by pathogens of parasitoses of environmental objects
    In this section, an attempt is made to analyze literature data and the results of our own studies to determine the levels of pollution of various environmental objects (soil, surface water, drinking water, sewage, vegetables, etc.), in which the development of the epidemic process with parasitosis is suspended and distribution is excluded
  7. Features of the development and spread in the environment of pathogens of helminthiases and intestinal protozoa
    The need to study this issue is due to the fact that various types of helminths and intestinal pathogenic protozoa are released into the environment at different stages of their development. So, cysts of dysenteric amoebas, giardia, and balantidia, released from the host’s body, are already invasive for humans, while pinworm eggs laid by the female on the skin of the perianal region,
  8. Destruction of microorganisms in the environment
    To destroy microorganisms in the environment, sterilization and disinfection are used. Sterilization is the complete release of environmental objects from microorganisms and their spores. There are physical, chemical and mechanical methods of sterilization. The most common methods of physical sterilization include autoclaving and dry heat sterilization. Autoclaving
  9. METHODS OF DISINFECTION FROM CURATIVES OF PARASITOSIS OF VARIOUS ENVIRONMENTAL OBJECTS
    METHODS OF DISINFECTION FROM CURRENT ANALOGUES OF VARIOUS OBJECTS
  10. MICROBIAS IN THE ENVIRONMENT
    Microbes of water. Microbes fall into the water from the surface of the earth, as well as from the air with rain and dust. The concentration of microbes in water is not the same. So, in the water of springs, artesian wells contains very few microbes. Many microbes are found in the water of ponds, lakes, rivers, especially near settlements, since the water here is polluted by sewage, garbage, etc. As you move away from
  11. Hygienic assessment of vibration in the environment
    Scientific and technological progress, urbanization have led to the fact that in the urban environment a new physical factor has appeared - vibration. The area of ​​its distribution has gone beyond industrial production, vehicles. Unwanted mechanical vibrations began to occur in residential areas, in residential and public buildings. Of particular relevance is the problem of vibration in residential buildings.
  12. Hygienic assessment of electromagnetic radiation in the environment
    The development of television, radio communications, radar, the expansion of the network of high-voltage power lines, the use of high-frequency energy in various fields of the national economy and in everyday life has led to a significant increase in the level of electromagnetic radiation in cities and towns. Electromagnetic waves of different ranges, including radio frequency, exist in nature, forming a natural
  13. Hygienic regulation of harmful substances in the environment and food
    Hygienic regulation is mandatory for all toxic substances entering the human body from the environment - air, water, soil, food, materials in contact with food, etc. Any chemical is toxic under certain exposure conditions. Toxicity - the ability of a substance to harm a living organism. On the human body
  14. Methods of experimental study of the timing of development and survival of helminth eggs in the environment
    When studying the timing of development and survival of helminth eggs, special experiments with artificial laying of samples at various environmental objects are required. The experiments must be carried out, on the one hand, under conditions that are closest to the natural ones, and on the other, under which samples with helminth eggs would be stored in the environment and it would be easy to extract them for
  15. THE ROLE OF THE ENVIRONMENT IN THE PRESERVATION AND DEVELOPMENT OF CURRENTS OF HELMINTOSIS AND INTESTINAL PROTOSIS
    The role of the environment in the spread of parasitic diseases of humans, animals and plants. In it, many types of parasites go through one of the stages of their biological development cycle. In this regard, environmental objects understand not only soil, water, crops, but also living organisms that are intermediate, complementary or reservoir hosts
  16. Closed loop circulation
    The occurrence of extrasystolic PVZH due to the circulation of excitation along a closed path in a dog’s infarction heart was directly demonstrated using isochronous mapping of ventricular activation [90]. Circulating excitations with regular extrasystolic grouping are caused by characteristic disorders of the conduction in the potential circulation pathway, depending on tachycardia.
  17. Evaluation of the effectiveness of recreational activities in the foci of parasitosis
    When assessing the effectiveness of health-improving measures in foci of parasitoses, the specialists of the Center for Sanitary Epidemiological Supervision (TsGSEN) monitor the contamination of intestinal pathogenic protozoa by eggs and larvae of helminths, cysts (oocysts) of the intestinal pathogenic protozoa (soil, cultivated crops, hands, etc.) and affection (incidence) population parasitic diseases.
