Abstract
The spread of antimicrobial-resistant bacteria in natural environments is a global concern. In the present study, we investigated the distribution of cefotaxime-resistant Aeromonas hydrophila in the gills and intestines of freshwater fish. Bacteria carrying the ampH, bla, and cphA1 genes were more frequently isolated from the gills, and most were assigned to ST1068. A genetically related strain was identified not only in fish but also in the river water. These results suggest that fish may be a valuable tool for monitoring environmental contamination caused by antimicrobial-resistant bacteria.
