Abstract
Burkholderia contaminans is a member of the Burkholderia cepacia complex (Bcc), a pathogen with increasing prevalence among cystic fibrosis (CF) patients and the cause of numerous outbreaks due to the use of contaminated commercial products. The antibiotic resistance determinants, particularly β-lactamases, have been poorly studied in this species. In this work, we explored the whole genome sequence (WGS) of a B. contaminans isolate (FFH 2055) and detected four putative β-lactamase-encoding genes. In general, these genes have more than 93% identity with β-lactamase genes found in other Bcc species. Two β-lactamases, a class A (Pen-like, suggested name PenO) and a class D (OXA-like), were further analyzed and characterized. Amino acid sequence comparison showed that Pen-like has 82% and 67% identity with B. multivorans PenA and B. pseudomallei PenI, respectively, while OXA-like displayed strong homology with class D enzymes within the Bcc, but only 22-44% identity with available structures from the OXA family. PCR reactions designed to study the presence of these two genes revealed a heterogeneous distribution among clinical and industrial B. contaminans isolates. Lastly, blaPenO gene was cloned and expressed into E. coli to investigate the antibiotic resistance profile and confers an extended-spectrum β-lactamase (ESBL) phenotype. These results provide insight into the presence of β-lactamases in B. contaminans, suggesting they play a role in antibiotic resistance of these bacteria.

High-Quality Draft Genome Sequence of Burkholderia contaminans CH-1, a Gram-Negative Bacterium That Metabolizes 2-Azahypoxanthine, a Plant Growth-Regulating Compound. GENOME ANNOUNCEMENTS 2017; 5:5/41/e01148-17.

Abstract
Burkholderia contaminans strain CH-1 converts 2-azahypoxnathine to 2-aza-8-oxohypoxanthine, plant growth-regulating compounds, by oxidation. We report here the high-quality draft genome sequence of B. contaminans CH-1. The genome contains 8,065 protein-coding sequences, including several genes possibly involved in metabolizing 2-azahypoxanthine.
