| Bacteremia due to extended-spectrum-ß-lactamase-producing Aeromonas spp. at a medical center in Southern Taiwan. | Although extended-spectrum-ß-lactamase (ESBL)-producing aeromonads have been increasingly reported in recent years, most of them were isolates from case reports or environmental isolates. To investigate the prevalence of ESBL producers among Aeromonas blood isolates and the genes encoding ESBLs, consecutive nonduplicate Aeromonas blood isolates collected at a medical center in southern Taiwan from March 2004 to December 2008 were studied. The ESBL phenotypes were examined by clavulanate combinat ... | 2011 | 21968366 |
