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...

مقدمه: سودوموناس آئروژینوزا، مهم‌ترین باکتری بیماری‌زایی است که در بیماران دچار سوختگی و بستری در بیمارستان، عفونت ایجاد می‌کند. وجود سویه‌های تولیدکننده بتالاکتاماز که نسبت به اکثر داروهای بتالاکتام مقاوم هستند مشکلات جدی در درمان این بیماران بوجود می‌آورد. هدف این بررسی، ارزیابی تولید پلاسمیدی بتالاکتاماز در سویه‌های سودوموناس آئروژینوزا است. روش کـار: 80 ایزوله از سودوموناس آئروژینوزا از بیم...

This article contributes to the nascent literature on housing for Degrowth. It recognises that plays a pivotal role in creation and perpetuation of socio-ecological injustices, therefore must be core strategic element transition towards Degrowth society. I argue deeper integration bottom-up, scalable strategies class politics proposals order create widespread emancipatory social transformation ...

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...

1.2. Morphisms between locales. We introduced the above ideas using a map of simplicial sets f : X → Y , but in actuality the definitions of F∗ and F∗ work whenever F is a open morphism of locales, as we shall soon see. To get to that point, however, it is best to start all over, by taking X and Y to be arbitrary locales and considering an arbitrary adjunction f∗ : Y //X : f∗ oo as a morphism F...

The prevalence of extended-spectrum beta-lactamase-producing strains was demonstrated in 5 of 44 (11.4%) Escherichia coli, 17 of 43 (39.5%) Klebsiella pneumoniae, 3 of 50 (6.0%) Enterobacter cloacae, and 2 of 25 (8.0%) Citrobacter freundii strains at a teaching hospital in China. Nineteen of these 27 strains expressed CTX-M-3 beta-lactamase (pI 8.6). A subset of the clinical isolates expressing...

A conjugative IncL/M plasmid (pSEM) conferring resistance to gentamicin, amikacin, kanamycin, sulfonamides, and expanded-spectrum cephalosporins was found in pathogenic strains of Salmonella enterica serotype Typhimurium. Resistance to aminoglycosides was encoded by a sul1-type class 1 integron (In-t3). An extended-spectrum beta-lactamase gene, bla(SHV-5), was identified 3. 5 kb downstream of t...
