    Abstract:

    ObjectiveTo analyze the distribution and pulsedfield gel electrophoresis (PFGE) of pathogenic bacteria causing infectious diarrhea in a district of Beijing from 2011 to 2013,  and  provide basis for tracing infection sources.MethodsA total of 1 179 stool specimens of  infectious diarrhea from patients in a diarrhea outpatient department from January 2011 to December 2013 were collected, all isolated pathogens were identified by serotyping and PFGE analysis.Results330 enteric pathogens were isolated from 1 179 specimens, the top 4 bacteria were Shigella spp.(28.18%,n=93),Salmonella spp.(20.91%, n=69),Vibrio parahaemolyticus(13.33%, n=44),and diarrheagenic Escherichia coli(3.33%, n=11). 18 Shigella sonnei isolates were identified as 8 PFGE patterns, clustering similarity was close to 88%;  69 Salmonella spp. strains belonged to 18 serotypes and 41 PFGE patterns,  Salmonella senftenberg and Salmonella enteritidis had dominant patterns; no dominant PFGE patterns were obviously identified among 23 strains of Vibrio  parahaemolyticus.ConclusionThe serotypes and PFGE patterns of pathogenic bacteria in infectious diarrhea in past three years showed a wide distribution characteristics, the dominant PFGE patterns of Salmonella spp.and Shigella spp. need to be paid more attention, and outbreak of  infectious diarrhea caused by Salmonella spp.and Shigella spp. should be alerted.
