Abstract:
Objective To understand the status quo of Salmonella infection in the patients with infectious diarrhea in Zhongshan city .Methods The fecal samples collected from 6 417 outpatients or inpatients with infection diarrhea in our hospital from January 2010 to December 2013 were performed the Salmonella culture ,isolation and identification and at the same time the serological clas-sification and the pulsed-field gel electrophoresis (PFGE) were performed .Results Among 6 417 samples ,460 strains of Salmonel-la were detected with the isolation rate of 7 .17% .Salmonella infection was dominated by children infection .The Salmonella infec-tion rate in children aged less than 1 years was 52 .4% (241 cases) ,followed by children aged 1- < 3 years ,which was 36 .7% (169 cases) .In the serological classification ,the most of detected Salmonella was salmonella typhimurium 46 .1% ,accounting for 46 .1% , Stanley salmonella accounting for 13 .5% and Salmonella enteritidis accounting for 8 .7% .The PFGE homology analysis showed that in the XbaI enzyme digestion spectral band ,26 PFGE band types had 100% homology .Conclusion Salmonella is one of the main pathogenic bacteria causing diarrhea and serious impact on health ,which is worthy of clinicians to pay attention to .
