In this thesis the ecology of bacteria and phage interactions is elucidated. Lytic phages, active against Pseudomonas aeruginosa, were isolated and characterised for their potential use as therapeutic agents. The contribution of bacterial quorum sensing for a rapid development of anti-phage resistance was tested experimentally and with mathematical modeling. In addition to the evaluation of the effect of single phages, the influence of a variety of resident viruses on an ecosystem was investigated. Therefore, the contribution of the virome to an existing or developing dysbiosis was examined in human lung samples of patients suffering from chronic obstructive pulmonary disease and healthy individuals.
