Production of beta-lactamases, the enzymes that degrade beta-lactam antibiotics, is the most widespread and threatening mechanism of antibiotic resistance. In the past, extensive research has focused on the structure, function, and ecology of beta-lactamases while limited efforts were placed on the regulatory mechanisms of beta-lactamases. Recently, increasing evidence demonstrate a direct link...

During the past decade, there has been an emergence of carbapenems-resistant Enterobacteriaceae that produce carbapenamases, enzymes that efficiently hydrolyze carbapenems, as well as most βlactam drugs (Queenan et al., 2007). New Delhi Metallo-beta-lactamases-1 (NDM-1) are one such carbapenamase that makes bacteria resistant to a broad range of betalactam antibiotics. These include the antibio...
Aims: This study aimed to screen for Beta Lactamases (BLs) and other resistant bacteria among patients admitted the emergency unit of Yaoundé University Teaching Hospital (YUTH).
 Study Design: was a cross-sectional hospital-based study.
 Place Duration Study: conducted at Bacteriology YUTH, Yaoundé- Cameroon between February June 2020.
 Methodology: Seventy-Five urine samples we...
Sir: Ampicillin, carbenicillin and cephalosporins are beta-lactam antibiotics effective against some gram-negative bacteria. However, they may be neutralized by enzymes, usually beta-lactamases. Different betalactamases have been found among enterobacteria1^ Although ampicillin and carbenicillin are closely related, cross resistance does not always exist. The occurrence of a segregation in the ...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...
Abstract Background Infections are common complications in patients with cancer. Data on antimicrobial resistance is important to guide empirical therapy. However, rates varies among different regions and countries and, general, higher Latin America. There limited data from these this region. The aim of work determine the frequency antibiotic susceptibility profiles, as well identify most frequ...
