| [prevalence of extended-spectrum beta-lactamases in nosocomial escherichia coli and klebsiella spp. strains isolated from blood cultures]. | the aim of this study was to determine the prevalence of extended-spectrum beta-lactamases (esbls) in nosocomial bacteremia isolates of escherichia coli, klebsiella pneumoniae and klebsiella oxytoca at hacettepe university adult hospital in ankara, turkey. a total of 344 blood culture isolates of e. coli (n=244), k. pneumoniae (n=86) and k. oxytoca (n=34) were included in the study from january 2003 to november 2005. only one isolate from one patient was tested in the study. the isolates with ce ... | 2007 | 18173077 |
| [carbapenem resistance in esbl positive enterobacteriaceae isolates causing invasive infections]. | the aim of this study was to investigate the presence of carbapenem resistance in enterobacteriaeceae isolates recovered from invasive infections, in hacettepe university hospital, ankara, turkey, between 2005-2009, by phenotypic and genotypic methods. a total of 210 non-duplicated escherichia coli (n= 153), klebsiella pneumoniae (n= 47) and klebsiella oxytoca (n= 10) isolates which were all determined to be extended-spectrum beta-lactamase (esbl) positive with the bd phoenix automated identific ... | 2014 | 24506716 |
| virulence properties of extended spectrum β-lactamase-producing klebsiella species in meat samples. | the present study was carried out to identify virulence properties (siderophores, serum resistance, and hemolysin) and antibiotic resistance in extended spectrum β-lactamase (esbl)-producing klebsiella isolates from 60 calf and chicken meat samples purchased from various supermarkets in ankara, turkey. of the 45 klebsiella isolates, 24 (53%) were identified as k. oxytoca and 21 (47%) were identified as k. pneumoniae. a high proportion of klebsiella isolates had virulence factors such as hemolyti ... | 2011 | 21477469 |
