Objective. To identify bacterial interactions at the site of infection in cystic fibrosis patients and to assess their possible effects on the course of infection. Materials and Methods. The following strains were used in this study: Alcaligenes faecalis LGBP strain, isolated from the environment; clinical isolates of Pseudomonas aeruginosa; Achromobacter xylosoxidans, Acinetobacter baumannii, Alcaligenes faecalis, and Bacillus subtilis strains; the standard laboratory P. aeruginosa PAO1 strain and its lysogens by temperate bacteriophages of various species, and its phageresistant mutants.
