Burkholderia cenocepacia is an important respiratory pathogen in persons with cystic fibrosis. We compared the proteomes of clinical and environmental isolates of B. cenocepacia by using a 2D liquid separation method coupled with mass spectrometry. Proteome maps of four B. cenocepacia isolates were generated. In the first dimension, 5 mg of protein from each isolate was fractionated by chromatofocusing (CF) in the range of pH 4.0-7.0. In the second dimension, each CF fraction was separated by NPS-RP-HPLC. Results of the 2D liquid separation were visualized as 2D UV maps, which allowed direct comparison of proteomes with high resolution and reproducibility. From the proteomic comparison of the four isolates, 38 of 96 differentially abundant proteins were identified by peptide mass fingerprinting and MS/MS sequence analysis using a partially annotated B. cenocepacia protein database. Many of the identified proteins in the clinical isolates are involved in gene translation and bacterial virulence such as transmissibility, resistance, and quorum sensing.
