In vivo transmission of a plasmid containing the KPC-2 gene in a single patient
Here we describe a case of in vivo horizontal interspecies transmission of a KPC-2-producing plasmid from a Klebsiella pneumoniae to an Enterobacter aerogenes strain in the same patient. The patient's gut flora initially contained a carbapenem-susceptible E. aerogenes strain and 10 days after admission a KPC-2-positive K. pneumoniae. Three months after

KPC-2-NDM-1-producing Serratia marcescens: first description in Peru
Two clonal extensively-resistant S. marcescens were isolated in Peru. The presence and transferability of extended-spectrum β-lactamases and IMP, KPC, NDM, OXA-48 and VIM were determined.

In silico identification and experimental validation of hits active against KPC-2 β-lactamase. [PDF]
Bacterial resistance has become a worldwide concern, particularly after the emergence of resistant strains overproducing carbapenemases. Among these, the KPC-2 carbapenemase represents a significant clinical challenge, being characterized by a broad ...

Emergence of Carbapenemase Producing Klebsiella Pneumonia and Spread of KPC-2 and KPC-17 in Taiwan: A Nationwide Study from 2011 to 2013. [PDF]
The emergence of carbapenemase-producing Klebsiella pneumoniae (CPKP) has become a great concern worldwide. In this study, 994 non-duplicate, carbapenem non-susceptible Klebsiella pneumonia isolates were collected in Taiwan from 2011 to 2013 for ...

Phosphate sensitivity of KPC-2: a hidden variable in β-lactamase kinetics. [PDF]
ABSTRACT The catalytic activity of β-lactamases, particularly class A enzymes like KPC-2, is central to β-lactam antibiotic resistance. While phosphate buffers are widely used in enzymatic assays due to their physiological relevance, their potential to interfere with enzyme function remains ...

Elucidating the role of Trp105 in the KPC‐2 β‐lactamase [PDF]
AbstractThe molecular basis of resistance to β‐lactams and β‐lactam‐β‐lactamase inhibitor combinations in the KPC family of class A enzymes is of extreme importance to the future design of effective β‐lactam therapy. Recent crystal structures of KPC‐2 and other class A β‐lactamases suggest that Ambler position Trp105 may be of importance in binding β ...

First Description of KPC-2-Producing Pseudomonas putida in Brazil [PDF]
ABSTRACT This work reports the identification of the first case of a KΡC-2-producing Pseudomonas putida isolate (PP36) in Brazil. The PP36 isolate was resistant to all the antimicrobials tested except polymyxin B.

Emergence of Klebsiella pneumoniae ST258 with KPC-2 in Poland [PDF]
Plasmidic KPC β-lactamases in gram-negative pathogens are of the highest clinical and epidemiologic concern, conferring resistance to all β-lactams, including carbapenems (15, 18). The main KPC producer is Klebsiella pneumoniae, but other species are being identified as well (15).

Boronic acid inhibitors of the class A beta-lactamase KPC-2 [PDF]
The rapid rise of antimicrobial resistance is one of the greatest challenges currently facing medical science. The most common cause of resistance to β-lactam antibiotics is the expression of β-lactamase enzymes, such as KPC-2. As such the development of
