A 269-kilobase conjugative plasmid, pK29, from a Klebsiella pneumoniae strain was sequenced. The plasmid harbors multiple antimicrobial resistance genes, including those encoding CMY-8 AmpC-type and CTX-M-3 extended-spectrum beta-lactamases in the common backbone of IncHI2 plasmids. Mechanisms for dissemination of the resistance genes are highlighted in comparative genomic analyses.

Klebsiella pneumoniae is a clinically significant opportunistic bacterial pathogen as well as a normal member of the human microbiota. K. pneumoniae strain IA565 was isolated from a tracheal aspirate at the University of Iowa Hospitals and Clinics. Here, we present the genome sequence of K. pneumoniae IA565.

A clinical isolate and a nonclinical isolate of Klebsiella pneumoniae were found to exhibit nonheritable tolerance in response to antimicrobial compounds. The draft genome sequences of both isolates are presented here.

Klebsiella pneumoniae given by aerosol was significantly less virulent in mice and monkeys than when given by intranasal (mice) or intratracheal (monkeys) instillation.

We report here the complete genome sequence ofKlebsiella pneumoniaestrain YH43, isolated from sweet potato. The genome consists of a single circular chromosome of 5,520,319 bp in length. It carries 8 copies of rRNA operons, 86 tRNA genes, 5,154 protein-coding genes, and thenifgene cluster for nitrogen fixation.

A Klebsiella pneumoniae ompA mutant was more susceptible to antimicrobial peptides (APs) than the wild type. Susceptibility did not result from surface changes other than the absence of OmpA. Our data suggest that OmpA is implicated in the activation of yet-unknown systems dedicated to ameliorating AP cytotoxicity.

The Klebsiella pneumoniae strain LCT-KP182 acquired hemolytic properties after space flight. Here, we present the draft genome sequence of this strain.

Klebsiella pneumoniae is the most common clinically important opportunistic bacterial pathogen and its infection is often iatrogenic. Its drug resistance poses a grave threat to public health. The genomic data reported here comprise an important resource for research on phage therapy in the control of drug-resistant bacteria.

Klebsiella pneumoniae shows increasing emergence of multidrug-resistant lineages, including strains resistant to all available antimicrobial drugs. We conducted whole-genome sequencing of 178 highly drug-resistant isolates from a tertiary hospital in Lahore, Pakistan. Phylogenetic analyses to place these isolates into global context demonstrate the expansion of multiple independent lineages, in...

β-Lactamase inhibitory protein II (BLIP-II) is a potent inhibitor of class A β-lactamases. KPC-2 is a class A β-lactamase that is capable of hydrolyzing carbapenems and has become a widespread source of resistance to these drugs for Gram-negative bacteria. Determination of association and dissociation rate constants for binding between BLIP-II and KPC-2 reveals a very tight interaction with a c...
