چکیده

Genes encoding the CMY-2, CTX-M-14, and SHV-12 beta-lactamases were detected in three of five Escherichia coli isolates from fecal samples from healthy chickens which showed resistance or diminished susceptibility to extended-spectrum cephalosporins. A -42 mutation at the promoter region of the ampC gene was detected in the other two isolates.

Phylogenetic typing and detection of extended-spectrum β-lactamases in Escherichia coli isolates from broiler chickens in Ahvaz, Iran

This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...

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

ABSTRACT        Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum β-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...

Molecular epidemiology of CTX-M-producing Escherichia coli isolates at a tertiary medical center in western Pennsylvania.

A combination of phenotypic and genotypic methods was used to investigate 70 unique Escherichia coli clinical isolates identified as producing extended-spectrum beta-lactamases (ESBLs) at a medical center in Pittsburgh, PA, between 2007 and 2008. Fifty-seven isolates (81%) produced CTX-M-type ESBLs, among which CTX-M-15 was predominant (n = 46). Isolates producing CTX-M-2, -9, -14, and -65 were...

Genetic detection of extended-spectrum beta-lactamase-containing Escherichia coli isolates from birds of prey from Serra da Estrela Natural Reserve in Portugal.

Extended-spectrum beta-lactamase-containing Escherichia coli isolates were detected in 32 of 119 fecal samples (26.9%) from birds of prey at Serra da Estrela, and these isolates contained the following beta-lactamases: CTX-M-1 (n = 13), CTX-M-1 plus TEM-1 (n = 14), CTX-M-1 plus TEM-20 (n = 1), SHV-5 (n = 1), SHV-5 plus TEM-1 (n = 2), and TEM-20 (n = 1).

Determining frequency of Escherichia coli producing beta lactamase CTX-M and SHV in hospital and non-hospital clinical specimens in Isfahan

Background and aim: Antimicrobial resistance is a worldwide problem causing health threats. Escherichia coli is one of the most important bacteria that causes resistance problems. The aim of this study was to evaluate the frequency of Escherichia coli, a extended spectrum beta-lactamase producing CTX-M and SHV, in hospital and non-hospital clinical specimens in Isfahan.   Methods: In this stu...
