The extended-spectrum-lactamases-producing Escherichia coli has rapidly spread worldwide. Escherichia coli has been becoming much more resistant to β-lactam antibiotics and other commonly available antimicrobials. We investigated the prevalence, resistance, and probable gene type of extended spectrum beta-lactamases (ESBLs) using minimum inhibitory concentrations (MICs) testing and polymerase c...
The purpose of this study was to determine the appropriate antibiotic for extended-spectrum beta-lactamases (ESBLs) screening and confirmatory tests in Escherichia coli and Klebsiella pneumoniae. The sensitivity of each antibiotic recommended by the National Committee for Clinical Laboratory Standards (NCCLS) to screen for ESBL production was compared. A total of 271 E. coli and 185 K. pneumoni...
In a UK survey of the occurrence of extended spectrum beta-lactamases, 96 hospitals submitted a total of 3951 non-selected, non-duplicate isolates of Enterobacteriaceae from 100 patients in each hospital, 206 of these cultures being mixed and, therefore, discarded. These isolates were initially screened for strains likely to produce extended-spectrum beta-lactamases (ESBLs) by MIC determination...
Background & Aims: Considering the importance of drug resistance among pathogenic bacteria and their treatment problems, this study aimed to determine the prevalence of extended-spectrum beta-lactamases (ESBLs), including TEM, SHV, and OXA genes among the isolated Escherichia coli and Klebsiella pneumoniae obtained from urine specimens of kidney transplant patients. Materials & Methods: The ba...
background : unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...
Urinary tract infections (UTIs) are among the most common diagnosed in clinical practice. Treatment is often initiated before microbiological confirmation and anti-microbial susceptibility testing. With rapidly rising antibiotic resistance treatment failures not uncommon. Beta-lactamase production by gram-negative bacteria causing UTI commonest mode of drug resistance. The aim current study was...
Background and purpose: Extended spectrum beta lactamases (ESBLs) are important causes of multidrug resistance (MDR) Escherichia coli. ESBL genes are usually located on conjugative plasmids or on integron structures. The aim of this study was to detect ESBLs on class I integron in Escherichia coli isolated from clinical samples. Materials and methods: A descriptive cross-sectional study was ...
The prospective project MOSAR was conducted in five rehabilitation units: the Berck Maritime Hôpital (Berck, France), Fondazione Santa Lucia (Rome, Italy), Guttmann Institute (GI; Barcelona, Spain), and Loewenstein Hospital and Tel-Aviv Souraski Medical Center (TA) (Tel-Aviv, Israel). Patients were screened for carriage of Enterobacteriaceae resistant to expanded-spectrum cephalosporins (ESCs) ...
