Hypermucoviscous polymyxin-resistant Klebsiella pneumoniae from Kolkata, India: Genomic and phenotypic analysis.

Abstract

OBJECTIVES\nHere we report the draft genome sequence of a colistin-resistant hypermucoviscous Klebsiella pneumoniae isolated from a hospitalised patient with acute kidney injury in Kolkata, India.\n\n\nMETHODS\nWhole genomic DNA was sequenced using an Illumina HiSeq platform. The generated reads were de novo assembled using SPAdes v.3.7.1. Genome annotation was performed using the NCBI Prokaryote Genome Annotation Pipeline (PGAP) v.4.6. The sequence type (ST), capsular type, antimicrobial resistance and virulence-related genes were predicted from the genome sequence.\n\n\nRESULTS\nKlebsiella pneumoniae KP26 belonged to ST147. The assembly comprised 63 contigs (>1000\u2009bp) with a total read length of 5 560 935\u2009bp and a total of 5399 coding sequences. The isolate was resistant to most β-lactams, aminoglycosides, quinolones, fosfomycin, trimethoprim, sulphonamides and polymyxins. No mcr genes were detected in the genome.\n\n\nCONCLUSION\nIsolate KP26 is a hypermucoviscous, multidrug-resistant K. pneumoniae strain that may represent an emerging high-risk clone associated with severe infections in India.
