关于水环境中沙门氏菌抗药性的信息有限。在本研究中，我们调查了日本宫崎市城区上游、中游和下游地区雅江沙门氏菌的分布情况。采用脉冲场凝胶电泳法分析耐药沙门氏菌的遗传关系。上游、中游和下游分离株对至少一种抗菌药的耐药率分别为23%(耐药株/总分离株 = 11/44)、3%(1/34)和32%(12/38)。从下游收集的11株多药耐药沙门氏菌菌株具有共同的遗传模式，属于同一聚类，相似性水平为100%。多重耐药沙门氏菌来自相同的来源，存在于人类居住附近的一条城市河流中。
There is limited information regarding antimicrobial resistantSalmonellain the aquatic environment. In this study, we investigated the distribution of antimicrobial resistantSalmonellain the Yae River at sites upstream, midstream and downstream of the urban area of Miyazaki City, Japan. Pulsed field gel electrophoresis was performed to evaluate the genetic relationship among antimicrobial resistantSalmonella. The percentage of isolates that were resistant to at least one antimicrobial agent in upstream, midstream, and downstream sites was 23% (resistant isolates/total isolates = 11/44), 3% (1/34) and 32% (12/38), respectively. The 11 isolates of multidrug‐resistantSalmonellacollected from downstream were classified to have a common genetic pattern belonging to the same cluster with a 100% similarity level. The multidrug‐resistantSalmonellawere obtained from an identical source and were present in an urban river near human habitation.
