Abstract:
Objective To understand non-typhoid Salmonella in diarrhea patients from Guangdong province in order to timely discover the outbreaks caused by them as well as to grasp the serotypes, antibiotic resistance and pulse-field gel electrophoresis (PFGE) types of those strains isolated from this surveillance program. Methods Salmonella strains from diarrhea patients were detected and all the positive strains were tested by serum agglutination, antibiotic susceptibility and PFGE. Results 71 nontyphoid Salmonella strains were isolated from 1128 stoop samples, with a positive rate of 6.29 %. All the strains were divided into 29 serotypes, with Salmonella serotype enteritidis and typhimurium showing the most common serotypes. Most of the strains were sensitive to cephalosporins and quinolones. The antibiotic resistance rates of S. typhimurium were higher than S. enteritidis and S. stanley. Other than S. enteritidis, all the serotype strains did not have the same type of PFGE. 17 S. enteritidis strains digested by Xba Ⅰ were divided to 8 PFGE types while the PFGE 4 type appeared the most common one. 12 S. enteritidis strains were typed again by Sfi Ⅰ and Not Ⅰ , and there were still 3 groups of strains showing the same PFGE pattern. Conclusion Most of the infection caused by non-typhoidal Salmonella was sporadic in Guangdong province in 2007. Cephalosporins and quinolones seemed the best in curing the infection of non-typhoidal Salmonella at the clinics.
