Topic: Pathogenicity factors of microorganisms.

  1. IPT caused by potentially pathogenic microorganisms
    Common causative agents of PTI are well-known microorganisms such as E. coli, Proteus, enterococci. E. coli (E, CoH) is widespread in nature, found mainly in the intestines of humans, livestock, poultry, etc. With secretions from the intestine, it enters the soil, water, and various environmental objects. Only certain types of E. coli cause toxic infections.
  2. Topic: The role of microorganisms in the infectious process.
    Forms of interaction of micro- and macroorganisms: mutualism, commensalism, parasitism. Infection as a form of parasitism. The evolution of microbial parasitism. The concept of sapronoses. Pathogenicity of microorganisms, definition. Obligatory pathogenic, conditionally pathogenic, non-pathogenic microorganisms. Virulence, definition, units (Dlm, LD50 and

  7. Pathogenicity factors
    The main factor is a capsule that protects bacteria from the microbicidal potential of phagocytes and leads them away from the action of opsonins. Unencapsulated strains are almost avirulent and are rare. Most of the pool of anti-pneumococcal ATs are AT to Ag capsules. An important function of the capsule and M-protein is also to ensure adhesion on the mucosa. Significant value
  8. The influence of environmental factors on microorganisms
    The life of microorganisms is closely dependent on environmental conditions. Both plants, macroorganisms, and the microworld are significantly affected by various environmental factors. They can be divided into three groups: chemical, physical and
  9. The influence of microorganisms and environmental factors on the quality of products
    Food products containing 30% water or more are a good breeding ground for microorganisms. During propagation, microorganisms secrete enzymes that decompose proteins (proteolytic), fats (lipolytic), carbohydrates (amylolytic) to intermediate or final decomposition products. At the same time, the properties of the products change for the better or for worse. The ability of microorganisms to improve

  14. LESSON 18 TOPIC. PROFESSIONAL DISEASES. PATHOLOGY CAUSED BY EXTERNAL FACTORS
    Motivational characteristic of the topic. Knowledge of topic materials is necessary for their successful mastery in clinical departments. In the practical work of a doctor, this knowledge is necessary for the clinical anatomical analysis of sectional observations and for comparing clinical data with the results of biopsy study. The general purpose of the lesson. Learn to identify macro - and microscopic signs of acute and

The effect of abortion on the reproduction of subsequent offspring. 9. Hormonal contraception - pluses and
  16. General ideas about pathogenic microflora
    Each microorganism is a complex system of biochemical reactions that changes its orientation depending on the living conditions. The microecological system on the mucous membrane, consisting of many types of bacteria, according to scientists, is a "biochemical reactor", the focus of metabolism, in which it is enormously dependent and difficult to predict. Detailed study in
  17. Pathogenicity at the body level
    A detailed discussion of this aspect is not our task, but briefly we will express our point of view on it. Doctors evaluate the pathogenicity of parasites at the body level, not without reason believing that it is the cause of the clinical manifestations of the disease. However, this is only one side of the host-parasitic relationship, in which at least three of their features are focused: - degree
  18. The spread of microorganisms in nature.
    Microorganisms are widespread in nature: they live in air, in water and in soil. Depending on the environment, all microorganisms can be divided into three groups: saprophyte (located mainly in the soil), epiphytes (located on the surface of living plants), parasites (live in the host cells). Microflora of the soil. Soil is the main source of distribution.
