[Interactions in the parasite-host system in chronic obstructive lung diseases].

The interactions in "parasite-host" system were studied in 120 patients with chronic obstructive pulmonary diseases (COPD) living in Samara. The significant interrelation between the composition of intestinal and pneumotropic microflora was revealed. It is conditioned both by the mechanisms of cooperation between some types of bacteria and by their translocation from one organs to another. The data obtained demonstrate the complex influence of abnormal microbial ecology in lungs and intestine on formation of "parasite-host" system and the significance of its function in COPD pathogenesis. The results of investigation show the necessity to include the measures for correction of microbial ecology disorders into the general complex of COPD therapy.
