Hypervirulent Klebsiella pneumoniae strains have been increasingly reported worldwide, and there is emergence of carbapenem resistance among them. Here, we report the genome sequences of three carbapenem-resistant hypervirulent K. pneumoniae isolates isolated from bacteremic patients at a tertiary-care center in South India.

Klebsiella pneumoniae is a Gram-negative pathogen frequently associated with antibiotic-resistant nosocomial infections. Bacteriophage therapy against K. pneumoniae may be possible to combat these infections. The following describes the complete genome sequence and key features of the pseudo-T-even K. pneumoniae carbapenemase (KPC)-producing K. pneumoniae myophage Miro.

We investigated a novel Japanese isolate of sequence type 11 (ST11), the Klebsiella pneumoniae carbapenemase-2 (KPC-2)-producing K. pneumoniae strain Kp3018, which was previously obtained from a patient treated at a Brazilian hospital. This strain was resistant to various antibiotic classes, including carbapenems, and harbored the gene blaKPC-2, which was present on the transferable plasmid of ...

We document here the in vivo transfer of bla(KPC-2) between intensive care unit-acquired and a commensal strain of K. pneumoniae in a French patient after his repatriation from Greece. This first report of an emerging KPC-producing strain in France raises further concerns about the spread of carbapenem resistance among Enterobacteriaceae.

We sequenced a novel conjugative blaKPC-2-harboring IncN plasmid, pYD626E, from an Escherichia coli sequence type 648 strain previously identified in Pittsburgh, Pennsylvania. pYD626E was 72,800 bp long and carried four β-lactamase genes, blaKPC-2, blaSHV-12, blaLAP-1, and blaTEM-1. In addition, it harbored qnrS1 (fluoroquinolone resistance) and dfrA14 (trimethoprim resistance). The plasmid pro...

A novel tannase producing bacterial strain was isolated from rhizospheric soil of Acacia species and identified as Klebsiella pneumoniae KP715242. A 3.25-fold increase in tannase production was achieved upon optimization with central composite design using response surface methodology. Four variables namely pH, temperature, incubation period, and agitation speed were used to optimize significan...

Klebsiella pneumoniae strain WCHKP1845, recovered from the sputum of a patient with pneumonia, was resistant to colistin and carried the carbapenemase gene blaNDM-1 Here, we report its 5.4-Mb draft genome sequence, comprising 140 contigs with an average 57.33% G+C content. The genome contains 5,118 coding sequences and 88 tRNA genes.

Objective: Green synthesis, characterization of silver nanoparticles (AgNPs) and study of the synergistic effect of AgNPs with antibiotic doxycycline against Klebsiella pneumonia. Methods: AgNps were synthesized from bacteria isolated from samples obtained from petroleum soil. After characterization of the nanoparticles, the antibacterial activity of the nanoparticle was studied, and simultaneo...

BACKGROUND Klebsiella pneumoniae is a leading cause of severe hospital-acquired respiratory tract infections and death but little is known regarding the modulation of respiratory dendritic cell (DC) subsets. Plasmacytoid DC (pDC) are specialized type 1 interferon producing cells and considered to be classical mediators of antiviral immunity. METHOD By using multiparameter flow cytometry analy...
