title: [Distribution and molecular type ofSalmonellafrom external environment in Henan province].
abstract: Objective:To understand the distribution ofSalmonellain external environment in Henan province, and explore the distribution of different serotypes of theSalmonellaand their homology.Methods:A total of 4 488 samples were collected form animal dung, meat products and kitchen utensils, and identified by biochemical tests and serotyped by serum agglutination reaction. The predominant serotypes were further typed by PFGE.Results:A total of 324Salmonellastrains were detected in these samples, the detection rate was 7.21%. The 324Salmonellaisolates belonged to 39 serotypes,S. enteritidis(24.07%,78/324) andS. derby(20.37%,66/324) were predominant. Forty six strains ofS. enteritidisand 30 strains ofS. derbywere divided into 12 and 17 molecular patterns by digestion withXba Ⅰ, while chicken and swine were the predominant animal hosts.Conclusions:Serotyping of external environmentSalmonellawere phenotypically diverse and the serotype ofSalmonellafrom different sources were different. The same clone was prevalent in same area. It is necessary to strengthen supervision and surveillance to ensure food safety.
