Abstract：Objective To study the relationship among the Salmonella enterica serotype Senftenberg isolates recovered from different regions and sources and analyze their antimicrobial susceptibilities. Methods Antimicrobial susceptibilities of 70 Senftenberg isolates were performed by K-B disk diffusion method, and pulsed field gel electrophoresis (PFGE) molecular subtyping method was applied to analyze their genetic relationships. Results Seventy isolates displayed low resistant rates for most antibiotics, but for sulfafurazole, resistant and intermediate resistant isolates reached more than 60%. Additionally, 3 isolates displayed resistance to ceftiofur. The results of PFGE analysis showed that 70 isolates could be divided into 42 different PFGE patterns. Some isolates from Shanghai, Beijing and Nanjing, which were isolated from human, food and environment respectively, showed the exactly same PFGE pattern. The results suggested that they had a close relationship. Conclusion Salmonella enterica serotype Senftenberg displays genetic polymorphism and may infect human by the contaminated environment and food. We should enhance surveillance and avoid further dissemination of this pathogen.
