This review summarizes the results of studies on the composition of microbial communities in the airways of healthy individuals and patients with asthma. Modern molecular genetic technology of the microbial identification, which are based on a sequence determination of encoding proteins genes conserved regions. These regions form the 16s-subunit ribosomal RNA in microorganisms of different species. These genes are detected by sequencing markers characteristic of individual microorganisms and their phylogenetic groups, and allow to perform a deep analysis of the microbiota in healthy volunteers and patients with chronic bronchoobstructive diseases. So, apparently healthy human bronchial tree is characterized by low bacterial contamination (most typical representatives here are the genera Pseudomonas, Streptococcus, Prevotella, Fusobacteria and Veilonella, much less potentially pathogenic Haemophilus and Neisseria are represented). In bronchial asthma patients the lower respiratory tract microbiota undergoes a qualitative transformation: as compared to healthy individuals the number of Proteobacteria increases and the number of Bacteroidetes decreases. Severe asthma in children is associated with significant respiratory tract Staphylococcus spp. insemination. Association between the asthma developing higher risk in young children and organisms such as Haemophilus, Moraxella and Neisseria spp. It is of considerable interest to determine the role of the microbiome in the development of human diseases of the bronchopulmonary system, and to understand the impact of the microbes communities as a course of disease and the important factor for the development of resistance to therapy.
