Abstrakt: | Background: The production of extended-spectrum β-lactamases (ESBLs) confer resistance to the commonly used beta-lactam antimicrobials and ESBL-producing bacteria render treatment difficulty in human and veterinary medicine. ESBL-producing bacteria have emerged in livestock in recent years, which may raise concerns regarding possible transfer of such bacteria through the food chain. The swine industry is important in Taiwan, but investigations regarding the status of ESBL in swine are limited. Results: We collected 275 fecal swab samples from piglets with diarrhea in 16 swine farms located in central and southern Taiwan from January to December 2015 and screened them for ESBL-producing Escherichia coli. ESBL producers were confirmed phenotypically by combination disc test and genotypically by polymerase chain reaction and DNA sequencing. The occurrence rate of ESBL-producing E. coli was 19.7% (54 of 275), and all were obtained in swine farms located in southern Taiwan. bla Conclusions: ESBL-producing E. coli from piglets with diarrhea were isolated from swine farms located in southern Taiwan. The most commonly detected bla were bla |
