BACKGROUND AND PURPOSE Data on the epidemiology of OXA-type extended-spectrum beta (beta)-lactamases (ESBLs) are limited due to difficulty of identification by routine microbiology laboratories. We determined the prevalence rate of OXA-type beta-lactamases among extended-spectrum cephalosporin (ESC)-non-susceptible Pseudomonas aeruginosa isolates at a university hospital in southern Taiwan. M...

Observations indicate that turbulence in the interstellar medium (ISM) is supersonic ($M_{\rm turb}\gg1$) and strongly magnetized ($\beta\sim0.01-1$), while intracluster (ICM) it subsonic turb}\lesssim1$) weakly ($\beta\sim100$). Here, $M_{\rm turb}$ turbulent Mach number $\beta$ plasma beta. We study properties of shocks induced these disparate environments, including distribution shock number...

The objective of this study was to determine whether antibiotic exposure is associated with extended-spectrum-beta-lactamase- or AmpC-producing Escherichia coli or Klebsiella pneumoniae infections in children. We collected extended-spectrum-beta-lactamase- or AmpC-producing E. coli or K. pneumoniae isolates and same-species susceptible controls from normally sterile sites of patients aged ≤21 y...

We investigate non-inertial effects induced by a rotating frame on non-relativistic quantum harmonic oscillator as well of the topology associated to screw dislocation, which corresponds distortion vertical line into spiral. To do this, we obtain analytical solutions time-independent Schr\"odinger equation for this potential in background. The expressions energy spectrum are obtained and four s...

The secondary structures of human C-reactive protein (CRP) and serum amyloid P component (SAP) in D2O-based solutions in the presence or absence of calcium, magnesium, and phosphorylcholine have been investigated using Fourier transform infrared spectroscopy. Quantitative analysis provided estimations of about 50% beta-sheet, 12% alpha-helix, 24% beta-turn, and 14% unordered structure for CRP a...

Objective. To study the sensitivity level of extended spectrum beta-lactamase-producing Enterobacteriaceae to Carbapenems (Imipenem, Ertapenem) marketed in Morocco and discusses the place of Ertapenem in the treatment of extended spectrum-beta-lactamase-producing. Materials and Methods. A retrospective study of 110 extended spectrum beta-lactamase-producing Enterobacteriaceae. Isolates obtained...

INTRODUCTION Antimicrobial resistance is a growing concern with implications for animal health. This study investigated the prevalence of antimicrobial resistance among commensal and environmental Escherichia coli isolated from animals sampled in referral hospitals in the UK. MATERIALS AND METHODS Resistant Escherichia coli isolated from animal faeces and practice environments were tested for...

New extended-spectrum beta-lactamase GES-11 was detected in Acinetobacter baumannii BM4674. The enzyme conferred resistance to beta-lactams, including aztreonam, and reduced susceptibility to carbapenems. The structural gene was part of a class 1 integron borne by self-transferable plasmid pIP847. GES-type beta-lactamases have not been reported previously in A. baumannii.

background extended-spectrum beta-lactamases (esbls) are a group of enzymes that hydrolyze antibiotics, including those containing new cephalosporins, and they are found in a significant percentage of escherichia coli and klebsiella pneumoniae strains. with the widespread use of antibiotics, difficulties with infection therapy caused by drug resistant organisms, especially those that have acqui...
