Introduction: Enterobacter cloacae strains have been isolated from Eastern Cape hospitalised patients. Methodology: We have molecularly characterised blaOXA-48-, blaIMPand blaVIM-expressing E. cloacae isolates demonstrating resistance to carbapenems from five hospitals by multilocus sequence typing. Organism identification and antimicrobial susceptibility testing was done using automated system...

The blaIMP gene coding for the IMP-1 metallo-beta-lactamase produced by a Pseudomonas aeruginosa clinical isolate (isolate 101/1477) was overexpressed via a T7 expression system in Escherichia coli BL21 (DE3), and its product was purified to homogeneity with a final yield of 35 mg/liter of culture. The structural and functional properties of the enzyme purified from E. coli were identical to th...

The purpose of this study was to detect carbapenemase genes in clinical isolates of carbapenem-resistant Enterobacteriaceae (CRE) obtained from patients admitted to Hua-Hin Hospital, Prachuab Khiri Khan Province, Thailand between January and December 2014. Screening of CRE was initially determined using disk diffusion method, and subsequently using modified Hodge test (MHT). Multiplex PCR was e...

metallo-β-lactamase (mbl) producing pseudomonas aeruginosa has been reported to be an important nosocomial infection. its intrinsic and acquired resistance to various antimicrobial agents and its ability to develop multidrug resistance imposes a serious therapeutic problem. different clinical samples were collected from public and private hospitals in baghdad city, iraq. bacterial identificatio...

In Brazil, carbapenem-resistant Pseudomonas aeruginosa isolates are closely related to the São Paulo metallo-β-lactamase (SPM) Brazilian clone. In this study, imipenem-resistant isolates were divided in two sets, 2002/2003 and 2008/2009, analysed by pulsed field gel electrophoresis and tested for the Ambler class B metallo-β-lactamase (MBL) genes blaSPM-1, blaIMP and blaVIM. The results show a ...

pseudomonas aeruginosa is among the most important pathogens in the nosocomial infections. a genetic mobile element, the integron, is one of the major agents involved in dissemination of multi-drug resistance among gram negative bacteria. during a descriptive study from october 2009 to august 2010, some 130 p. aeruginosa clinical isolates were collected from different wards of three hospitals i...

Carbapenem resistance due to the acquisition of metallolactamase (M L)-encoding genes has increased rapidly among Pseudomonas aeruginosa strains in Asia, Europe, and Latin America (7). However, these resistance genes are rarely detected in carbapenem-resistant P. aeruginosa strains from North America, particularly in the United States, where only three well-documented occurrences of M L-produci...

Hospital-acquired infections with Acinetobacter spp. have been reported worldwide (13). Success of the organism is attributed to its ability for long-term survival in a hospital environment and its ability to rapidly acquire resistance to antimicrobials (2). Carbapenems have been the agents of choice for serious Acinetobacter sp. infections, but unfortunately the clinical utility of this class ...
