Abstract:
Objective To understand the serotype, drug resistance and pulsed field gel electrophoresis (PFGE) typing of Salmonella isolated from meat products in Hengyang from 2020 to 2022, so as to provide scientific data for the prevention and control of food-borne Salmonella infection in our city. Methods All 101 Salmonella isolated from meat products were serotyped, drug sensitivity tests were performed with micro broth dilution method, molecular typing was performed using PFGE, clustering analysis was performed with BioNumerics software, and statistical analysis was performed using SPSS 18.0 software. Results The total detection rate of Salmonella from meat sources in Hengyang City from 2020 to 2022 was 38.55% (101/262). Totally 23 different serotypes were detected in the 101 strains of Salmonella among which S. London (21.78%, 22/101),was the dominant serotypes. Seventy nine Salmonella strains showed different levels of drug resistance, with a multi drug resistance rate of 42.57% (43/101). Eighty nine different PFGE bands were found in the 101 strains of Salmonella, with a similarity of approximately 55% to 100%. Conclusion Different Salmonella Serotype are widely distributed, and the antibiotic resistance rate is very high. The PFGE map are polymorphic, and the homology of PFGE bands in Salmonella from different sources is relatively low.
