Draft genome sequence analysis of a high carbapenem-resistant Klebsiella quasipneumoniae subsp. quasipneumoniae strain isolated from an HIV-positive patient with pneumonia.

OBJECTIVES:The rapid spread of Klebsiella spp. is recognised as a major threat to public health owing to a rise in the number both of healthcare- and community-acquired infections. Here we report the draft genome sequence of a high carbapenem-resistant Klebsiella quasipneumoniae subsp. quasipneumoniae strain (Cln185) isolated from a human immunodeficiency virus (HIV)-positive patient with pneumonia. METHODS:Classical microbiological methods were applied to isolate and identify the strain. Genomic DNA was sequenced using an Illumina HiSeq platform and the reads were de novo assembled into contigs using CLC Genomics Workbench. The assembled contigs was annotated and whole-genome sequencing (WGS) was performed. RESULTS:WGS analysis revealed that the genome comprised a circular chromosome of 5 406 774bp with a GC content of 57.73%. Three important antimicrobial resistance genes (blaIMP-38, blaOKP-B-6 and blaDHA-1) were detected. In addition, genes conferring resistance to aminoglycosides, β-lactams, fluoroquinolones and tetracycline were also identified. CONCLUSION:The draft genome sequence reported here will lay the foundation for future research on antimicrobial resistance and pathogenic mechanisms in K. quasipneumoniae subsp. quasipneumoniae and also will promote comparative analysis with genomic features among different sources of clinically important multidrug-resistant strains.
