摘要

本研究的目的是评估波兰主要河流瓦尔塔河泉水中携带整合子大肠杆菌的情况。我们分离了18株含有1类和/或2类整合子的菌株(12株大肠杆菌、3株Pantea sp.、2株弗氏柠檬酸杆菌和1株氧化克雷伯菌)。1类整合子包含aadA1、dfrA7、dfrA17、dfrA1-aadA1和dfrA17-aadA5基因盒阵列,而2类整合子的遗传含量是稳定的,由sat2-ad1基因盒阵列组成。携带整合子的菌株对4-11种抗菌药物具有耐药性,最常见的是对磺胺甲恶唑、氨苄青霉素、哌拉西林、甲氧苄啶和甲氧苄胺/磺胺甲恶灵。

Spring of Warta River as a Source of Antibiotic-Resistant Coliform Bacteria
The aim of the study was to evaluate the occurrence of integron-carrying coliform bacteria in the spring water of Warta river, a major river in Poland. We isolated 18 strains (12 Escherichia coli, three Pantoea sp., 2 Citrobacter freundii, and 1 Klebsiella oxytoca) harbouring class 1 and/or class 2 integrons. Class 1 integrons contained aadA1, dfrA7, dfrA17, dfrA1-aadA1, and dfrA17-aadA5 gene cassette arrays, whereas the genetic content of class 2 integrons was stable and consisted of sat2-aad1 gene cassette array. The strains carrying integrons were resistant to 4–11 antimicrobials, most frequently to sulfamethoxazole, ampicillin, piperacillin, trimethoprim, and trimethoprim/sulfamethoxazole.
