Clavulanic acid, sulbactam, and tazobactam are inhibitors of a variety of plasmid-mediated beta-lactamases. However, inhibition data for these three inhibitors with a wide range of different plasmid-mediated beta-lactamases have not yet been compared under the same experimental conditions. A number of groups have inferred that clavulanic acid inhibits extended-spectrum TEM and SHV beta-lactamas...

OBJECTIVES The present study was carried out to evaluate the current prevalence of the clonal group O25b:H4-B2-ST131 among extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (ESBLEC) collected in the Hospital Vall d'Hebron in Barcelona (Spain) with regard to other clonal groups and to characterize their genetic background. METHODS Ninety-four consecutive non-duplicate ESBLEC isol...

OBJECTIVES This study aimed at evaluating the AID ESBL line probe assay for the detection of extended-spectrum β-lactamase (ESBL) and KPC carbapenemase genes in Enterobacteriaceae. METHODS The AID ESBL line probe assay was verified for accuracy of its probes using PCR products from clinical ESBL Enterobacteriaceae strains harbouring TEM, SHV and CTX-M ESBL genes and KPC genes and mutant fusio...

BACKGROUND Some genetic and phenotypic variables are associated among distinct microbial populations. OBJECTIVES The associations between multi-drug resistance (MDR) phenotypes, prevalence of antibiotic resistance integrons (ARIs), bla SHV, bla TEM and bla CTX-M gene carriage and genetic fingerprints of random amplified polymorphic DNA (RAPD), confirmed by pulsed field gel electrophoresis (PF...

مقدمه: امروزه ظهور ارگانیسم­های مولد آنزیم بتالاکتاماز وسیع­الطیف(ESBL)  یکی از معضلات درمانی به شمار می­روند. بتالاکتامازهای وسیع­الطیف از جمله آنزیم­هایی هستند که عامل ایجاد مقاومت نسبت به آنتی­بیوتیک­های بتالاکتام محسوب می­شوند. هدف از این مطالعه تعیین الگوی مقاومت آنتی‏بیوتیکی و فراوانی ژن­های SHV و SHV-1  در سویه­های اشریشیاکلی مولد آنزیم بتالاکتاماز وسیع­الطیف جدا شده از افراد مبتلا به عف...

Background & Objectives:Extended-spectrum-B-lactamase (ESBL)-producing strains of Klebsiella Pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. This study was performed to determine the prevalence of ESBL-producing K. Pneumonia and to evaluate the frequency of TE...

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...

Journal: :Radical housing journal 2023

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 ...
