Background: Prevalence of co-existence of extended-spectrum β-lactamases (ESBLs), metallo-beta-lactamase (MBLs) and AmpC-β-lactamases producing isolates in these bacteria is a serious problem in treatment of infections. The aim of this study was to characterization co-existence of ESBLs, AmpC and MBLs in Escherichia coli and Klebsiella pneumoniae isolates from Khorramabad hospitals. Materials ...

Background and Objective: In developing countries, the steep increase in septicaemia cases is a major health problem that creates biggest challenge for clinicians selection of appropriate antimicrobial agents. This further complicated by development resistance organisms to agents, which mainstay treatment. The aim this study was determine patterns bacterial isolates associated with sepsis among...

A major reason for resistance of Enterobacteriaceae to beta-lactam antibiotics is production of ESBLs and AmpC beta-lactamases. As their more detailed description in poultry is unavailable in the Czech Republic, the presented study aimed at assessing their occurrence and molecular characteristics. A total of 154 composite samples from broilers and 150 cloacal swabs from turkeys were examined. P...

Extended-spectrum beta-lactamases (ESBLs) were present in high proportions of Escherichia coli (25% [9 of 36]) and Klebsiella pneumoniae isolates (17% [9 of 52]) causing pediatric septicemia at a tertiary hospital in Tanzania. Patients with septicemia due to ESBL-producing organisms had a significantly higher fatality rate than those with non-ESBL isolates (71% versus 39%, P = 0.039). This is t...

Extended spectrum β-lactamases (ESBLs) are enzymes produced by a variety of Gram negative bacteria which confer an increased resistance to commonly used antibiotics. They are a worrying global public health issue as infections caused by such enzyme-producing organisms are associated with a higher morbidity and mortality and greater fiscal burden. Coupled with increasing prevalence rates worldwi...

Ceftazidime-avibactam, aztreonam-avibactam, and comparators were tested by reference broth microdilution against 372 nonrepetitive Gram-negative bacilli (346 unselected plus 26 selected meropenem-nonsusceptible Enterobacteriaceae isolates) collected from 11 teaching hospitals in China in 2011 and 2012. Meropenem-nonsusceptible isolates produced extended-spectrum β-lactamases (ESBLs; e.g., CTX-M...

In November 1997, all Enterobacteriaceae isolated at 15 hospitals in Brooklyn were collected. Extended-spectrum beta-lactamases (ESBLs) were present in 44% of 409 Klebsiella pneumoniae isolates. Six isolates had reduced susceptibility to carbapenems, including two that were not susceptible to any of the antibiotics tested. Pulsed field gel electrophoresis revealed a commonality of resistant iso...

This study was conducted to detect the prevalence of Metallo-Beta-Lactamases (MBLs) and Extended Spectrum Beta-Lactamases (ESBLs) in bacterial isolates from clinical community settings two communities Delta State, Nigeria. Eighty four obtained blood, urine, wound stool patients subjects were analyzed identified by standard microbiological methods. Carbapenemase detection carried out using modif...

Enter obacteriaceae families are capable of producing the extended spectrum beta-lactamase (ESBL) enzyme, which results in highlevels resistance to all beta-lactam antibiotics. For effective antibiotic therapy, stop spread mechanisms, and forepidemiological reasons, their detection is crucial. 53 Gram negative isolates were detected using a standard methodology currentinvestigation, compared va...
