Abstract

The aadA genes, encoding resistance to streptomycin and spectinomycin, have been found as gene cassettes in different gram-negative and gram-positive bacterial species. The present study has revealed the sequence of a new gene, aadA5, integrated as a gene cassette together with the trimethoprim resistance gene dfr7 in a class 1 integron. The integron was located on a plasmid and was identified in a pathogenic porcine Escherichia coli isolate.

摘要

编码对链霉素和壮观霉素耐药性的aadA基因已在不同的革兰氏阴性和革兰氏阳性细菌物种中作为基因盒被发现。本研究揭示了一个新基因aadA5的序列,它与甲氧苄啶耐药基因dfr7一起作为一个基因盒整合在1类整合子中。该整合子位于一个质粒上,在一株致病性猪源大肠杆菌分离株中被鉴定出来。
