conclusions the results of this study phenotypically and genotypically confirmed the high frequency of esbl-producing strains, such as the ctx-m and ctx-m-1 genes, among enterobacteriaceae isolates in our region. therefore, use of antibiotic susceptibility testing for the detection of esbl isolates prior to the prescription of beta-lactam antibiotics is recommended. this could help prevent the ...
conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...
We investigated in vitro activities of piperacillin or cefoperazone alone and in combination with beta-lactamase inhibitors against Gram-negative bacilli. Piperacillin/tazobactam 8:1 lowered resistance for Escherichia coli, Serratia marcescens, Enterobactaer cloacae, Klebsiella pneumoniae and imipenem-susceptible Acinetobacter baumannii. When piperacillin was combined with sulbactam 2:1 or 4:1,...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases 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...
Activity of simulated cefditoren urinary concentrations was determined against seven Escherichia coli isolates. Bactericidal activity was obtained from 4 to 24 h against TEM-1 (penicillinase production/hyperproduction), TEM-34 (IRT-6), and TEM-116 (extended-spectrum beta-lactamase [ESBL]) and from 6 to 8 h against SHV/TEM-116 (ESBL) but never against SHV/TEM-1 (ESBL). Extension of bactericidal ...
Background and purpose: Extended Spectrum Beta Lactamases (ESBLs) are one of the most important health care issues all over the world. Uropathogenesis are responsible for life threatening infections in children. In this study we aimed at investigating the epidemiology of CTX, TEM and VEB genes in pediatric UTI. Materials and methods: Urine samples were collected during six months in Sari Bou...
The purpose of this study was to simultaneously screen for Extended-spectrum beta-lactamases (ESBL) and AmpC beta-lactamases in gram negative clinical isolates from four tertiary care hospitals and further to compare two detection methods three-dimensional extraction method and AmpC disk test for AmpC beta-lactamases. A total of 272 isolates were screened for ESBL and AmpC beta-lactamase by mod...
background extended-spectrum β-lactamase (esbl)-producing klebsiella pneumonia has become widespread in hospitals and is increasing in community settings. most of k. pneumonia that harbor these enzymes, display resistance to other unrelated antimicrobial agents and thus, often pose a therapeutic dilemma. objectives this study was conducted to determine the prevalence of esbl-producing k. pneumo...
In this study, it was aimed to investigate the presence of Klebsiella pneumoniae and phenotypically carbapenemase, extended-spectrum β-lactamase (ESBL), acquired-AmpC beta-lactamase, multiple antibiotic resistance isolates in faeces budgerigars parrots. A total 96 faecal samples belonging 54 42 parrots were used study. Cultivation performed on various media for identification pneuomiae from col...
