Escherichia coli of animal origin in Norway contains a blaTEM-20-carrying plasmid closely related to blaTEM-20 and blaTEM-52 plasmids from other European countries.
Sir, The situation regarding antimicrobial resistance in bacteria from food-producing animals in Norway is, in an international perspective, favourable. The resistance frequencies are moderate and the situation has been stable since the start of the Norwegian monitoring programme in the veterinary sector (NORM-VET) (www. vetinst.no) in the year 2000. We report the first bacterial isolate of ani...
متن کاملdetermination of antimicrobial resistance pattern and detection of blatem gene among clinical isolates of escherichia coli
background : unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...
متن کاملInvestigation of diversity of plasmids carrying the blaTEM-52 gene.
OBJECTIVES To investigate the diversity of plasmids that carry bla(TEM-52) genes among Escherichia coli and Salmonella enterica originating from animals, meat products and humans. METHODS A collection of 22 bla(TEM-52)-encoding plasmids was characterized by restriction fragment length polymorphism (RFLP), replicon typing (by PCR or replicon sequencing), susceptibility testing, assessment of p...
متن کاملFitness trade-offs in blaTEM evolution.
bla(TEM-1) expression results in penicillin resistance, whereas expression of many bla(TEM-1) descendants, called extended-spectrum beta-lactamases (ESBLs), results simultaneously in resistance to penicillins and extended-spectrum cephalosporins. Despite the expanded resistance phenotypes conferred by many ESBLs, bla(TEM-1) is still the most abundant bla(TEM) allele in many microbial population...
متن کاملdistribution of blatem, blashv and blactx-m genes among escherichia coli isolates causing urinary tract infection in children
background emerging antibacterial resistance rates and extended-spectrum-β-lactamase producing escherichia coli recovered from urinary tract infections (uti) is an increasing problem in different regions, limiting therapeutic options. objectives the aim of this study was the detection of blatem, blashv and blactx-m genes among escherichia coli strains causing urinary tract infection in children...
