Prevalence of Extended-spectrum Beta-lactamases (ESBL) Types blaTEM and blaSHV in Klebsiella pneumoniae Strains Isolated from Clinical Samples by PCR in Miandoab, West Azerbaijan
Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...
متن کاملFrequency of E. coli clinical isolates producing blaSHV and blaTEM extended-spectrum beta-lactamases
Introduction: Production of extended-spectrum beta-lactamase enzymes (ESBLs) in E. coli creates many problems for patients. These enzymes are located on transferable elements and can hydrolyze penicillins, broad-spectrum cephalosporins, and aztreonam. This study aimed to determine the clinical isolates of E. coli producing ESBLs of blaSHV and blaTEM in the city of Zanjan. Methods: This cross...
متن کاملThe Importance of Extended-Spectrum β-lactamases in Gram-Negative Enteric Bacilli and the Phenotypic Methods of detection
The production of β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in gramnegative bacilli. Therefore, it is important to identify the β-lactamases-producing bacteria for the treatment of caused infections. This article aimed to review the recent literature and guidelines regarding phenotypic detection of β-lactamases in common gram-negative bacilli in clinical sa...
متن کاملEpidemiology and genetics of CTX-M extended-spectrum β-lactamases in Gram-negative bacteria
CTX-M enzymes, the plasmid-mediated cefotaximases, constitute a rapidly growing family of extended-spectrum β-lactamases (ESBLs) with significant clinical impact. CTX-Ms are found in at least 26 bacterial species, particularly in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis. At least 109 members in CTX-M family are identified and can be divided into seven clusters based on thei...
متن کاملThe Association Between Genetic Variants in Extended Spectrum Beta-Lactamases and AmpC-producing Gram-Negative Bacilli and Antibiotic Resistance
Background and Objective: A large group of genes associated with extended-spectrum beta-lactamases (ESBL) and AmpC expression is involved in inducing antibiotic resistance in various bacteria. Identifying these genes and assessing their harboring will be crucial in determining the pattern of antibiotic resistance. This study aimed to characterize genetic variants in extended-spectrum beta-lacta...
