Microbial landscape

Microbial landscape characterisation of the Association of microorganisms in their interaction with each other and the environment; the concept was first formulated S. N. Vinogradsky in the study of soil microflora. Study of the properties and behavior as a separate species of microorganisms and their associations (see Biocenosis) is of great importance in medical Microbiology. In particular, for various parts of the human body (the mouth and nose, skin, gut, vagina, etc. are characteristic of this or that normal, or obligate microflora, i.e. the Association of certain kinds of microorganisms. The composition of microbial associations depends on the state of the organism as a whole and, in turn, has an impact on the host organism. Breach of the normal microflora of organism - the so-called dysbacteriosis - in some cases leads to different pathology. This has become especially important in connection with the widespread use of antibiotics. When suppressing the development sensitive to antibiotics species included in the normal microbial flora of the person (see), the conditions for rapid reproduction of antibiotic-resistant species of microbes (Proteus, wand blue-green pus, aureus, fungi of Candida). As a result, on the background of antibacterial therapy of complications, sometimes surpassing the severity of the underlying disease. Example heavy, and for weakened patients with life-threatening complications arising from the breach of the normal microflora of man are pseudomembranous enterocolitis (see Colica mucosa), and candidiasis (see).
