Objectives: Klebsiella spp. are regarded as major pathogens causing infections in humans and various animals. Here we report the draft genome sequence of a CTX-M-type beta-lactamase-producing Klebsiella quasipneumoniae subsp. similipneumoniae strain CHKP0062 isolated from a Yellow-margined Box turtle.
Methods: An Illumina-Solexa platform was used to sequence the genome of CHKP0062. Qualified reads were assembled de novo using Velvet. The draft genome was annotated by the NCBI Prokaryotic Genome Annotation Pipeline (PGAP). The resistome and virulome of the strain were investigated.
Results: A total of 5423 protein-coding sequences, 87 tRNAs, 24 rRNAs and 12 ncRNAs were identified in the 5 699 275-bp genome. CHKP0062 was assigned to sequence type ST2131 with the K-loci type as KL67. No virulence-associated genes were identified. However, numerous antimicrobial resistance genes were present in this strain. Plasmid contigs were assembled and revealed homology to the multidrug resistance plasmids pC15-K, pCTX-M3 and pKF3-94, with the carriage of the class A beta-lactamase genes bla(TEM-1b) and bla(CTX-M-3).
Conclusion: The genome sequence reported in this study will be useful for comparative genomic analysis regarding the dissemination of clinically important antibiotic resistance genes among Klebsiella spp. isolated from humans and animals.
