Rapid detection of extended-spectrum-β-lactamase-producing Enterobacteriaceae.
Enterobacterial strains producing clavulanic-acid-inhibited extended-spectrum β-lactamases (ESBLs) are increasingly reported worldwide. Conventional detection of ESBL production remains time-consuming (24 to 48 h). Therefore, the ESBL NDP (Nordmann/Dortet/Poirel) test was developed for a rapid identification of ESBLs in Enterobacteriaceae. This biochemical test was based on the in vitro detecti...

land. Furthermore, Ct. felis often feeds on humans. Clinicians encountering patients with fever or rash (or both) and a history of cat contact or flea bites should consider a diagnosis of R. felis. Laboratory confirmation of infection is not easy, but in vitro culture of R. felis, and hence material for a serologic assay for the diagnosis of human R. felis infections, has recently been describe...
متن کاملThe effect of silver nanoparticles on Gram-negative bacilli Resistant to Extended-Spectrum Β-Lactamase Enzymes
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...
متن کاملSalmonella enterica: Serotyping, Drug Resistance & Extended Spectrum of β-Lactamase (ESBLs)
Background & Objective: Genus Salmonella has more than 2400 serotypes. The two major groups are S.enterica and S.bongori. Important serotypes are situated in S.enterica group. Antibiotic therapy in salmonellosis is restricted to typhoid fever and acute infections. After the first reporting of resistance in S.Typhimurium DT 104, nowadays, developing of resistance in Salmonella, specially, ESBL p...
متن کاملCompetitive Exclusion Reduces Transmission and Excretion of Extended-Spectrum-β-Lactamase-Producing Escherichia coli in Broilers.
Extended-spectrum β-lactamases (ESBLs) and plasmid-mediated AmpC β-lactamases (pAmpC) are enzymes able to hydrolyze a large variety of β-lactam antibiotics, including third-generation cephalosporins and monobactams. Broilers and broiler meat products can be highly contaminated with ESBL- and pAmpC-producing Escherichia coli strains, also known as extended-spectrum cephalosporin (ESC)-resistant ...
