A total of 21 Salmonella strains were isolated from clinical cases in Yangzhou, China, and the surrounding areas from Feb 2011 to Dec 2011. All isolates were screened by PCR amplification for InvA gene, which is specific to the Salmonella genus. Thus, twenty-oneSalmonella were identified from the specimens. The isolates belonged to 6 serovars ofSalmonella. Both Salmonella typhimurium and Salmonella pullorum were the dominant serovars isolated. Results of susceptibility test show that a large percentage ofSalmonella were resistant to doxycycline (90.5%), polymyxin B (85.7%), streptomycin(85.7%), lomefloxacin (85.7%), and nalidixic acid (81.0%). The high resistance among these strains from infection animals suggested that essential measure such as infection control and drug rational use need to be taken.


Key words: Salmonella, isolation, identification, serovar, resistance.
