    Abstract: Although extended-spectrum β-lactamase (ESBL)-producing aeromonads have been increasingly reported in recent years, most of them were isolates of case reports or environmental isolates. To investigate the prevalence of ESBL-producers among Aeromonas blood isolates and the genes encoding ESBLs, consecutive non-duplicated 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 combination disk test and the cefepime-clavulanate ESBL Etest. Presence of ESBL-encoding genes, including blaTEM, blaPER, blaCTX-M, and blaSHV genes, were evaluated by polymerase chain reaction and sequence analysis. The results showed that four (2.6%) of 156 Aeromonas blood isolates, one A. hydrophila isolate and three A. caviae isolates, expressed an ESBL-producing phenotype. The ESBL gene in two A. caviae isolates was blaPER-3 gene, which was located in both chromosomes and plasmids demonstrated by Southern hybridization. Of four patients with ESBL-producing Aeromonas bacteremia, two presented with catheter-related phlebitis and the other two primary bacteremia. Three patients had been treated with initial non-carbapenem β-lactams for 5-10 days, and all survived. In conclusion, the ESBL producers among Aeromonas blood isolates exists, clinical suspicion of ESBL production should be raised in treating infections due to cefotaxime-resistant Aeromonas isolates.
