[Extended-spectrum beta-lactamases (ESBLs) producing bacteria].
TEM- or SHV-type extended-spectrum beta-lactamases(ESBLs) are of clinical concern in Europe and the United States, whereas bacterial strains producing such types of ESBLs had not been reported in Japan for many years. Toho-1, a different type class A ESBL, has been reported in 1995, in which any prototypical enzyme has not been identified so far. At present Toho-1 is the major ESBL in Japan, ho...
متن کاملBacteria Producing Extended Spectrum β-lactamases (ESBLs) in Hospitalized Patients: Prevalence, Antimicrobial Resistance Pattern and its Main Determinants
Background and Objective: There is a growing concern regarding the lack of new antibiotics, especially for multidrug-resistant bacteria that produce Extended Spectrum β-Lactamases (ESBLs). The present study aims to assess the prevalence of bacteria producing ESBLs, their antimicrobial resistance pattern, and its main determinants among hospitalized patients.Method...
متن کاملTwo different extended-spectrum beta-lactamases (ESBLs) in one of the first ESBL-producing salmonella isolates in Poland.
Two extended-spectrum beta-lactamase (ESBL)-producing salmonella isolates, Salmonella enterica serovar Enteritidis and Salmonella enterica serovar Typhimurium, were analyzed. Both isolates produced the CTX-M-3 ESBL; however, their bla(CTX-M-3) genes were located on different plasmids. The serovar Typhimurium isolate also expressed another ESBL, SHV-2a, and probably the two ESBL genes had been a...
متن کاملdetection of extended-spectrum β-lactamases (esbls) in escherichia coli
background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...
متن کاملPrevalence and molecular characterization of Extended Spectrum Beta-Lactamases (ESBLs) producing Escherichia Coli and Klebsiella Pneumoniae.
UNLABELLED The aim of this study was to determine the prevalence of ESBL-producing Escherichia coli and Klebsiella pneumoniae as well as genes encoding ESBLs. MATERIAL AND METHODS A total of 1207 non-repeat isolates of E. coli and K. pneumoniae were obtained from urine, tracheal aspirate, wound swab and blood from patients hospitalized at the University Clinics in Skopje. ESBL set and E-test ...
