Abstract
A novel qnr determinant emerged in ciprofloxacin-resistant Vibrio cholerae O1 from the Amazon region of Brazil. This qnrVC1 was in a typical class 1 integron. Its attC showed 89% identity with V. parahaemolyticus superintegron repeats. Analysis showed V. cholerae O1 carrying qnrVC2 associated with a V. cholerae superintegron repeat.
摘要
一种新型qnr决定簇出现在来自巴西亚马逊地区的耐环丙沙星霍乱弧菌O1中。这种qnrVC1存在于一个典型的1类整合子中。其attC与副溶血性弧菌超级整合子重复序列具有89%的同一性。分析表明，携带qnrVC2的霍乱弧菌O1与霍乱弧菌超级整合子重复序列相关。
