Among the 2,105 Enterobacteriaceae tested in a survey done in Portugal, 165 were nonsusceptible to carbapenems, from which 35 (26 Klebsiella pneumoniae, 3 Escherichia coli, 2 Enterobacter aerogenes, and 3 Enterobacter cloacae isolates and 1 Klebsiella oxytoca isolate) were confirmed to be carbapenemase producers by the presence of 30 Tn4401d-blaKPC-3, 4 intI3-blaGES-5, and one intI1-blaVIM-2 ge...
We describe the interspecies transmission of the plasmid-mediated blaKPC-3 gene, which confers carbapenem resistance, between clinically relevant gram-negative bacteria in a single patient. A KPC-3 producing Enterobacter aerogenes was isolated from a hospitalized patient previously colonized and then infected by a Klebsiella pneumoniae ST101 carrying the blaKPC-3 gene. The strains showed identi...
Results: The blaVIM gene was present in 34 (43.6%), blaIMP in five (6.4%) and none of the isolates from 2008 had blaNDM-1 or blaKPC genes. Among the isolates from 2012, blaNDM-1 gene was present in 47 (53.4%), blaVIM in 19 (24.4%), blaIMP in one (1.1%) and none had blaKPC. There were nine isolates during the two years which had multiple genes encoding carbapenemases; while 66 did not have any o...
The increasing incidence of carbapenem-resistant Enterobacteriaceae (CRE) - mediated hospital infections in China prompted a need to investigate the genetic basis of emergence of such strains. A nationwide survey was conducted in China covering a total of 1105 CRE strains collected from 25 geographical locales with results showing that acquisition of two carbapenemase genes, blaKPC-2 and blaNDM...
Forty-five KPC-producing Enterobacteriaceae strains were isolated from multiple departments in a Chinese public hospital from 2014 to 2015. Genome sequencing of four representative strains, namely Proteus mirabilis GN2, Serratia marcescens GN26, Morganella morganii GN28, and Klebsiella aerogenes E20, indicated the presence of blaKPC-2-carrying IncX6 plasmids pGN2-KPC, pGN26-KPC, pGN28-KPC, and ...
Sir, Carbapenem-resistant Enterobacteriaceae (CRE) pose a major threat to public health worldwide. One of the most frequently encountered mechanisms is the Ambler class A Klebsiella pneumoniae carbapenemase (KPC)-type enzyme. Since the initial report of a KPC-producing K. pneumoniae in 2001, these organisms have spread worldwide, mainly due to the spread of a single successful clone, sequence t...
In a 2008-2011 survey, 17,945 patients in 18 hospital units in Europe and Israel were screened for carriage of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae, resulting in identification of 124 positive patients. The isolates were dominated by Klebsiella pneumoniae sequence type 258 (ST258) KPC-2 and ST512 KPC-3, mainly from Greece and Italy, respectively, whereas Israel...
مقدمه: امروزه کلبسیلا پنومونیه مقاوم به چند دارو تولیدکننده بتالاکتامازها، یکی از عوامل مهم عفونت های بیمارستانی محسوب شده و مشکلات درمانی در دنیا ایجاد نموده اند. هدف از این مطالعه شناسایی کلبسیلا پنومونیه تولید کننده بتالاکتامازهای وسیع الطیف kpc (blakpc ) در نمونه های بالینی در ایران می باشد. مواد و روش ها: پس از تعیین هویت تا سطح گونه با استفاده از روش های کشت و بیوشیمیائی، تعیین حساسیت 180...
Sir, Since its first description in 1996, variants of KPC have spread throughout the world mostly in the ST258 clone of Klebsiella pneumoniae within isoforms of the Tn4401 transposon located on various plasmids. While the Middle East is considered as a reservoir of various carbapenemase-producing bacteria, to date the only Enterobacteriaceae carrying the blaKPC gene reported from the Arabian Pe...
OBJECTIVES To analyse the ongoing epidemiology of KPC-producing Enterobacteriaceae after a non-ST258 KPC-3-producing Klebsiella pneumoniae outbreak in a university hospital in Madrid, Spain. METHODS Enterobacterial isolates (one per patient based on bacterial identification and typing patterns) with carbapenem MICs higher than the EUCAST epidemiological cut-off values, a positive modified Hod...
