ABSTRACT
Recognized as a mobile genetic element, integron is correlated to the excision and integration of exogenous genes, especially bacterial resistance genes. However, most of the investigations focused on Gram-positive bacteria with few exceptions. In this study, Enterococcus faecalis was selected to investigate the excision and integration of class 1 integron. A total of eight plasmids were subjected to establish the transformants for excision and integration test. As results showed, positive excision assay was observed, which had been confirmed by the further integration assays and PCR amplification. The observation of class 1 integron mediated excision and integration of various exogenous antibiotics resistance genes should raise the attention of integrons as novel antibiotic resistance determinant in Gram-positive bacteria, especially in Enterococcus.
