There is limited information regarding antimicrobial resistant Salmonella in the aquatic environment. In this study, we investigated the distribution of antimicrobial resistant Salmonella in 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 resistant Salmonella . 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‐resistant Salmonella collected from downstream were classified to have a common genetic pattern belonging to the same cluster with a 100% similarity level. The multidrug‐resistant Salmonella were obtained from an identical source and were present in an urban river near human habitation.
