Plasmid-Mediated Quinolone Resistance Genes in <i>Escherichia coli</i> Urinary Isolates from Two Teaching Hospitals in Turkey: Coexistence of TEM, SHV, CTX-M and VEB-1 Type &#946-lactamases

PCR Detection of Plasmid Mediated TEM, SHV and AmpC β-Lactamases in Community and Nosocomial Urinary Isolates of Escherichia coli

Detection of TEM, SHV and CTX-M Antibiotic Resistance Genes in Escherichia coli Isolates from Infected Wounds

ABSTRACT &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum &beta;-lactamase (ESBL)-producing E. coli strains are resistant to third-generation cephalosporins. The three main genes involved in ESBL production are TEM, SHV and CTX-M. Detection of ESBL-producing E. coli is of importan...

PER, CTX-M, TEM and SHV Beta-lactamases in Clinical Isolates of Klebsiella pneumoniae Isolated from Tehran, Iran

Objective(s) Different types of extended spectrum beta-lactamases (ESBLs) are encountered in the clinical settings worldwide. There are a few studies regarding the prevalence of ESBL genes among Klebsiella pneumoniae isolates at Tehran especially those of blaPER and blaCTX. The aim of this study was to determine the prevalence of blaSHV, blaTEM ,blaPER and blaCTX genes among clinical K. pneumo...

Determination of Antibiotic Resistance Pattern and frequency of CTX-M, TEM, and SHV Β-Lactamase Encoding Genes among Shigella Isolates from Inpatients in Tehran, Iran

ABSTRACT              Background and Objectives: The emergence of extended-spectrum β-lactamase (ESBL)-producing Shigella spp. is becoming a health concern worldwide. This study aimed to investigate antibiotic resistance pattern and frequency of blaCTX-M, blaSHV, and blaTEM genes among Shigella isolates from patients in hospitals of Tehran, Iran.              Methods: In this cross-sectional ...

Prevalence of SHV/CTX-M/TEM (ESBL) Beta-lactamase Resistance Genes in Escherichia Coli Isolated from Urinary Tract Infections in Tehran, Iran

Abstract Background and objectives: Beta-lactamase enzymes are the most causes of resistance to antibiotics among gram-negative bacteria. Nowadays, Infections due to ESBLs are being increased throughout the world and is considered as a new burden to the health systems. This study aimed at determining the sensitivity pattern of E.coli isolates to beta-lactam antibiotics, and investigating the pr...
