Multiplex PCR for bla(CTX-M) & bla(SHV) in the extended spectrum beta lactamase (ESBL) producing gram-negative isolates.
BACKGROUND & OBJECTIVE Phenotyping is commonly used for detection of extended spectrum beta lactamase (ESBL) production in gram-negative isolates. ESBLs are mainly coded for by three important genes, namely bla(TEM), bla(SHV) and bla(CTX-M). In this study we used a multiplex PCR as a rapid method to identify two common genes (bla(CTX-M) & bla(SHV)) responsible for extended spectrum beta lactama...
متن کاملHigh prevalence of bla(CTX-M) extended spectrum beta-lactamase genes in Klebsiella pneumoniae isolates from a tertiary care hospital: first report of bla(SHV-12), bla(SHV-31), bla(SHV-38), and bla(CTX-M-15) in Brazil.
The aim of this study was to investigate the presence and prevalence of bla(TEM), bla(SHV), and bla(CTX-M) and bla(GES)-like genes, responsible for extended spectrum beta-lactamases (ESBLs) production in clinical isolates of Klebsiella pneumoniae collected from a Brazilian tertiary care hospital. Sixty-five ESBL producing K. pneumoniae isolates, collected between 2005 and 2007, were screened by...

conclusions considering the high prevalence of esbl genes (bla ctx-m, 87%; and bla tem, 82%), fluoroquinolones may be used as an alternative drug in treatment, although resistance to this family is increasing as well. as a result, this increasing trend should be prevented using appropriate guidelines for prescription. background escherichia coli is the most important as well as the most common ...
متن کاملdetection of bla tem and bla shvgenes among clinical isolates of e. coli from tehran hospitals
background and objectives: the pathogenic strains of escherichia coli cause severe septicemia, urinary tract infection and wound sepsis. resistance of this organism to the expanded-spectrum cephalosporins occurs via the production of extended-spectrum β-lactamases (esbls) such as tem and shv. these enzymes hydrolyze oxyimino cephalosporins (cefotaxime, ceftazidime) and monobactams (aztreonam). ...
متن کاملSpread of bla(CTX-M-type) and bla(PER-2) beta-lactamase genes in clinical isolates from Bolivian hospitals.
OBJECTIVES To assess the prevalence and types of genes encoding extended-spectrum beta-lactamases (ESBLs) in clinical isolates of Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp. from Bolivia. METHODS A total of 642 clinical isolates were collected consecutively during a 4 month period (September to December 2004). Resistance or reduced susceptibility to cefotaxime and/or cef...
