Described in the paper are the results of a study of differential expression of pathogenicity of B. cepacia and P. aeruginosa in subinhibiting concentrations (SIC) of cyprofloxacyne. While identifying genes expressing differentially in the antibiotic SIC, genes cepR B. cepacia and P. aeruginosa expressing without cyprofloxacyne in the cultivation medium and not expressing in the antibiotic SIC were detected. Finally, involvement of cepR B. cepacia in regulating the pathogenicity expression factors according to "quorum sensing" is under discussion.
