Abstract:
KPC-producing bacteria are considered one of the most worrisome multidrug-resistant micro-organisms in nosocomial infections. Here we report the draft genomes sequences of two KPC-2 and CTX-M-15 producing Klebsiella pneumoniae sequence type 15 (ST15) and Klebsiella variicola sequence type 32 (ST32) isolates obtained from clinical samples of patients in Rio de Janeiro. A genomic library was constructed using a Nextera XT Kit. An Illumina platform was used to perform whole-genome sequencing (WGS). WGS of isolates K. pneumoniae and K. variicola resulted in estimated genome sizes of 5 662 554 and 5 868 756 bp, respectively. Resistome analysis of the clinical strains revealed the presence of resistance genes to the following antimicrobials in K. pneumoniae: aminoglycosides [aadA1], [aph (3’)-Ia], [aph(3”)-Ib], [aac(6′)-Ib3], [aadA2] and [aph(6)-Id]; β-lactams (blaOXA-1, blaoxa-9, blaCTX-M-15, blaTEM-1, andblaSHV-28); carbapenem (blaKPC-2); fluoroquinolones [aac(60)-Ib-cr], [oqxA]and [oqxB]; fosfomycin [fosA]; macrolides [mph(A)] and [erm(B)]; phenicols [catB3]; sulfonamides [sul1]; trimethoprim [dfrA12] and tetracycline [tetA] and to K. variicola: aminoglycosides [aadA1], [aph (3)-IIa], [aac(6′)-Ib-cr] and [aph(6)-Id]; β-lactams (blaOXA-1, blaCTX-M-15, blaTEM-1B andblaLEN-2); carbapenem (blaKPC-2); fluoroquinolones [aac(60)-Ib-cr], [qnrB1], [oqxA]and [oqxB]; fosfomycin [fosA]; phenicols [catB3]; sulfonamides [sul2]; trimethoprim [dfrA14] and tetracycline [tetA]. The resistome revealed by this study might be a useful tool to elucidate the dissemination of nosocomial resistance genes in Rio de Janeiro.
