Changing Trend

SUMMARYTo monitor the changing trend of extended-spectrum β-lactamase (ESBL)-producing bacteria, a 7-year continuous study was launched in 2001 at the largest tertiary hospital in Taiwan. A significant increase over the study period was evident for ESBL-producing isolates of Escherichia coli (4·8–10·0%) and Klebsiella pneumoniae (15·0–23·4%). Molecular investigation conducted in three separate periods revealed the prevalent ESBL types and their genetic relatedness. CTX-M-producing isolates (73·8%) were more prevalent than SHV-type ESBLs (37·0%), the most frequent being CTX-M-14 (34·3%), CTX-M-3 (25·9%), and SHV-12 (25·7%). However, a marked increase of CTX-M-15-producing isolates from 2·1% in 2002 to 29·6% in 2007 was also noted. The increase of ESBL-producing isolates in both species may be mainly due to the horizontal transmission of resistance plasmids, while clonal expansion of some epidemic strains further added to the dispersion of ESBL-producing K. pneumoniae.
