Hence, it is imperative to identify and explore its dissemination traits. If CTX-M-15–producing E. coli continues to spread among different environments, therapeutic options in veterinary and human medicine will be greatly narrowed. E. coli is one of the gram-negative bacteria most frequently isolated from bottlenose dolphins. However, few studies about antimicrobial drug–resistant bacteria in dolphins have been published. We explored dissemination linkages between CTX-M-15–producing E. coli isolated from a marine dolphin (Tursiops truncatus) and clinical isolates collected during the same period from humans all over Portugal.
