BACKGROUND The aim of this study was the rapid identification of bla KPC gene in 38 Klebsiella pneumoniae clinical isolates with reduced susceptibility to carbapenems. The modified Hodge Test (MHT) was carried out to phenotypically determine whether resistance to carbapenems was mediated by a carbapenemase. The detection of the bla KPC gene was performed by real-time acid nucleic sequence-based...
Transfer of the bla(KPC) genes encoding the Klebsiella pneumoniae carbapenemase (KPC) are increasingly responsible for emerging carbapenem resistance. The modified Hodge test (MHT) is recommended for the detection of KPC. We compared MHT with a real-time polymerase chain reaction (PCR) assay targeting common subtypes of bla(KPC), using previously described forward and reverse primer sequences. ...
A real-time PCR assay was developed targeting the bla(KPC) responsible for Klebsiella pneumoniae carbapenemase (KPC)-mediated carbapenem resistance and was validated for testing colonies or enrichment broth cultures. The assay accurately detects KPC-containing strains with high analytical specificity and sensitivity.
OBJECTIVES The origin of KPC is unknown. The aim of this study was to detect progenitors of KPC in silico and to functionally verify their β-lactam hydrolysis activity. METHODS The sequence of KPC-2 was used to mine the NCBI protein sequence database. The best non-KPC hits were analysed by amino acid (aa) alignment and phylogenetic tree construction. Genes encoding KPC-2 homologues were expre...
چکیده سابقه و هدف: هدف از این مطالعه، تعیین شیوع ژن های متالوبتالاکتاماز (mbl) و کلبسیلا پنومونیه کارباپنماز (kpc) در بین ایزوله های سودوموناس آئروژینوزای جدا شده از بیماران مبتلا به سوختگی و سیستیک فیبروزیس بود. مواد و روش ها: این مطالعه توصیفی بر روی 70 و 30 ایزوله سودوموناس آئروژینوزای جدا شده از زخم بیماران مبتلا به سوختگی بیمارستان مطهری تهران و خلط بیماران مبتلا به سیستیک فیبروزیس بیمارس...
Strains of Klebsiella pneumoniae producing KPC-type beta-lactamases (KPC-Kp) are broadly disseminating worldwide and constitute a major healthcare threat given their extensively drug resistant phenotypes and ability to rapidly disseminate in healthcare settings. In this work we report on the characterization of two different capsular polysaccharide (CPS) gene clusters, named cpsBO-4 and cps207-...
We describe the first outbreak of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP), the infection control measures adopted and the shift in resistance patterns of isolates during antibiotic treatment. The ST258 KPC-KP strain exhibited a multiresistant antibiotic phenotype including co-resistance to gentamycin, colistin and tigecycline intermediate susceptibility. Isolates be...
