www.expert-reviews.com ISSN 1478-7210 © 2008 Expert Reviews Ltd 10.1586/14787210.6.5.671 The potential options available for treating serious infections caused by enterobacteria include penicillins (with or without β-lactamase inhibitors), cephalosporins, aztreonam, carbapenems, fluoroquinolones and, in certain situations only, aminoglycosides and colistin. Recently, tigecycline has been added ...
A total of 23 clinical isolates (15 Escherichia coli and 8 Klebsiella pneumoniae), resistant to cefotaxime and ceftazidime recovered during 2002 and 2003, were investigated for production of CTX-M extended spectrum beta-lactamase (ESBL) by phenotypic and molecular methods. The presence of ESBL was tested by NCCLS phenotypic confirmatory test using cephalosporin/clavulanate combination discs and...
The emergence of extended-spectrum beta-lactamase- (ESBL-) producing pathogenic bacteria at Kabale Regional Referral Hospital (KRRH), located in southwestern Uganda, is of great concern: a phenomenon that worries clinicians and other healthcare workers due to the serious threat they pose to patients. This current study aimed at determining the phenotypic detection of ESBL-producing strains of E...
BACKGROUND The increasing incidence of community acquired infection due to Extended-Spectrum Beta-Lactamase (ESBL) -Producing Enterobacteriaceae represent a great concern because there are few therapeutic alternatives. The fecal flora of children in the community can represent a reservoir for ESBLs genes which are located on highly transmissible plasmids and the spread of these genes among bact...

Abstract: Background and objectives: Antibiotic resistant to Antimicrobial agents is one of the most important concern in hospitals, which can lead to increased costs, treatment fails and mortality rates. The aim of this study was identification of Gram-negative bacilli resistant to extended-spectrum β-lactamase Enzymes (ESBLs) and determination of the effect of silver nanoparticles on the...

Beta-lactamase enzymes (BLs) have become the most worrisome mediators of antimicrobial resistance expressed by gram-negative bacteria (GNB). The multiple families of BLs have in common the ability to hydrolyze the -lactam rings of one or more members of the penicillins, cephalosporins, cephamycins, carbapenems, and monobactams. Extended-spectrum -lactamases (ESBLs) are a subset of BLs that conf...

BACKGROUND AND OBJECTIVES Pseudomonas aeruginosa is one of the most important Gram negative opportunistic bacteria which causes infection among burn patients. Resistance to the antibiotics in this group of bacteria is increased due to the activity of extended spectrum β-lactamase (ESBLs) genes. In the current study, we investigated the prevalence of two genes (blaPER-1 & blaOxa10 ) related β-la...
