摘要

In order to monitor salmonella contamination in chicken hatcheries during 2001 to 2007, fluff samples collected from different hatcheries in Taiwan were running bacterial isolation for resistant gene analysis. The salmonella isolation rates for the collected samples ranged from 0% to 4% in different years. From which, 55 salmonella isolates in 2002 and in 2006 were selected for the analysis of the resistant gene coding for integron, tetA, tetB, and PSE-1 by using polymerase chain reactions. These isolates contained more tetA and PSE-1 genes but less tetB gene in 2002 than in 2006. However, the presence of integron in 2002 and 2006 was 70% and 64%, respectively. The high existence of integron in the local isolates of salmonellae reveals a high risk of antibiotic resistant genes transferring by this element among different salmonellae.
