Carbapenem-hydrolysing beta-lactamase KPC-2 in Klebsiella pneumoniae isolated in Rio de Janeiro, Brazil.

OBJECTIVES The aim of this study was to characterize the KPC-type carbapenem-hydrolysing beta-lactamase, extended-spectrum beta-lactamases (ESBLs) and class 1 integrons among nosocomial Klebsiella pneumoniae isolated in Rio de Janeiro, Brazil. METHODS MICs were determined and isolates were screened for ESBLs, metallo-beta-lactamases (MBLs) and class A carbapenemase-producing phenotypes. The m...

Emergence of Serratia marcescens, Klebsiella pneumoniae, and Escherichia coli Isolates Possessing the Plasmid-Mediated Carbapenem-Hydrolyzing -Lactamase KPC-2 in Intensive Care Units of a Chinese Hospital

First occurrence of KPC-2-possessing Klebsiella pneumoniae in a Greek hospital and recommendation for detection with boronic acid disc tests.

OBJECTIVES To investigate the first KPC carbapenemase-producing Klebsiella pneumoniae isolate from a Greek hospital, including phenotypic methods to aid recognition of this resistance type. METHODS A carbapenem-resistant clinical isolate of K. pneumoniae was recovered from a hospitalized Greek patient. Detailed susceptibility testing was carried out by the agar dilution method. The isolate wa...

Rapid spread of carbapenem-resistant Klebsiella pneumoniae in New York City: a new threat to our antibiotic armamentarium.

BACKGROUND Carbapenem antibiotics are used to treat serious infections caused by extended-spectrum beta-lactamase-carrying pathogens. Carbapenem resistance has been unusual in isolates of Klebsiella pneumoniae. In this study, the prevalence and molecular epidemiologic characteristics of carbapenem-resistant K pneumoniae are analyzed, and the experience involving 2 hospital outbreaks is describe...
