چکیده

We report for the first time the isolation of CTX-M-15-producingEscherichia colistrains belonging to sequence type (ST) 410, ST224, and ST1284 in commercial swine in Brazil. TheblaCTX-M-15gene was located on F-::A9::B1 and C1::A9::B1 IncF-type plasmids, surrounded by a new genetic context comprising the IS26insertion sequence truncated with the ISEcp1element upstream ofblaCTX-M-15 These results reveal that commercial swine have become a new reservoir of CTX-M-15-producing bacteria in South America.

Antibiotic Susceptibility and Multi-drug Resistance of Escherichia coli Isolates Producing CTX-M and TEM Type Beta-lactamases in Mashhad, Iran, in 2010

Background & Aims: One of the most common causes of bacterial resistance to beta-lactam antibiotics is beta-lactamase producing. The aim of this study was to compare the antibiotic resistance of urinary Escherichia coli (E. coli) isolates producing CTX-M and TEM type beta-lactamases, and to determine the strains with co-resistance to multiple antibiotics in Mashhad, Iran. Methods: E. coli b...

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...

Characteristics of extended-spectrum β-lactamase–producing Escherichia coli isolated from fecal samples of piglets with diarrhea in central and southern Taiwan in 2015

BACKGROUND The production of extended-spectrum β-lactamases (ESBLs) confer resistance to the commonly used beta-lactam antimicrobials and ESBL-producing bacteria render treatment difficulty in human and veterinary medicine. ESBL-producing bacteria have emerged in livestock in recent years, which may raise concerns regarding possible transfer of such bacteria through the food chain. The swine in...

Background and purpose: Presence of extended spectrum β -lactamase (ESBL) genes plays an important role in spreading β -lactam antibiotic resistance in the producing strains of these enzymes. The resistance of gram-negative bacteria, such as Escherichia coli, to different antimicrobial agents, has increasingly been reported. This study was conducted to determine the prevalence of ESBL in Esc...
