Draft genome sequence of the strain 16-537536, isolated from a patient with bronchiectasis and its relationship to the Pseudomonas koreensis group of the Pseudomonas fluorescens complex.

Objective: The Pseudomonas koreensis group bacteria are usually found in soil and are associated with plants. Currently they are poorly described. Here we report on the whole genome sequence of a bacterial isolate from a patient with bronchiectasis that was first identified as P. koreensis, and on its position in the P. koreensis group.

Results: Strain 16-537536 was isolated from a patient with bronchiectasis from Spain and initially identified by MALDI-TOF as P. koreensis, a member of the Pseudomonas fluorescens complex. However, the average nucleotide identity analysis (ANIb) and whole genome alignments of the draft genome sequence of this strain showed it to be a member of the P. koreensis group of the P. fluorescens complex, but belonging to an undescribed species. In addition, based on ANIb analysis, the P. koreensis group contains several other unnamed species. Several genes for putative virulence factors were identified. The only antibiotic resistance gene present in strain 16-537536 was a class C β-lactamase. The correct identification of bacterial species from patients is of utmost importance in order to understand their pathogenesis and to track the potential spread of pathogens between patients. Whole genome sequence data should be included for the description of new species.
