Abstract

The study aimed to analyze antibiotic resistance determinants in a carbapenem-resistant Klebsiella pneumoniae by whole-genome sequencing (WGS). K. pneumoniae was isolated from a urine sample and it was characterized by 16S rDNA sequencing in Turkey. This strain was named as Kpn Rize-53-TR. Antimicrobial susceptibility testing was performed for seventeen antibiotics by VITEK-2 and the result was confirmed by MIC. The whole genome of isolate was sequenced by lllumina and was analysed by bioinformatic tools for MIST, replicon types, and antimicrobial resistance genes. The whole genome data was submitted to NCBI. The isolate was found to be resistant to all tested beta-lactam antibiotics and the highest MIC values were found for piperacillin, piperacillin/tazobactam (>= 128). No resistance to colistin and moderate susceptibility to amikacin and tetracycline was observed. The isolate carried 12 resistance genes belonging to 10 resistance classes; ere(A), fosA, oqxtl, cmlA1, aac(a)-IIa, bla(KPC-2), bla(TEM-)(1A), bla(SHV)(-)(67), bla(CTX-M-)(15), bla(OX)(A-1-2-9). Mutations were detected in gyrA (83Y) and parC (80I) genes. Clonal subtype of the isolate was ST147, and it had wzi420 and wzc38 alleles. Its serotype was O3/O3a. The bla(KPC-2) was firstly found in both ST147 clonal group in Turkey and in serotype O3/O3a in the world. By plasmid replicon typing, five plasmids IncEII(K), Col(BS512), IncR, IncFIA(HI1) and IncFIB(pQil) were determined in Kpn Rize-53-TR and bla(KPC)(-2) was located on IncFII(K) plasmid. The presence of bla(K)(PC)(-2) on the plasmid with other resistance genes accelerates its own spread together with other resistance genes.
