Abstract：We studied the serovars and PFGE types of Salmonella in patients with infectious diarrhea from 2013 to 2014, in order to provide scientific basis for the prevention and control of salmonellosis in Guiyang City. A total of 432 samples of stool specimens of diarrheal patients from 4 sentinel hospitals were collected to isolate Salmonella strains. The isolated Salmonella strains were further analyzed via serotypes and PFGE pattern. The positive rate of the surveillance Salmonella in Guiyang was 8.1%(35/432). The ratio of male and female was 1.5∶1. Salmonella infection was most in 0~5 years old. The positive rate was 8.91%.The difference of isolated rates of Salmonella was not statistically significant (P=0.052) in the four seasons. Nine serovars were identified in the 35 isolates. The most prevalent were Salmonella enteritidis and Salmonella typhimurium, account for 31.43% and 25.71% respectively. Eleven strains of Salmonella enteritidis were divided into 8 PFGE types, 9 strains of Samonella typhimurium were divided into 9 PFGE types, showed great genetic diversity. Results showed Salmonella enteritidis and Salmonella typhimurium were the dominant serotypes causing infectious diarrhea in Guiyang City. The PFGE types were great genetic diversity.
