Abstract：We investigated the infection situation, serotype distribution, sources of etiological food and drug resistance of Salmonella in foodborne disease patients in Henan Province in 2015 and 2016. We evenly arranged 15 sentinel hospitals in Henan Province in 2015 and 2016, and a total of 5 720 patient-defined cases were monitored, whose information was collected. A total of 221 Salmonella strains were isolated from the fecal of diarrhea patients, who were studied on serotyping, drug resistance and traceability of related etiological food, and the results were analyzed statistically. Results showed that the S. enteritidis, S. typhimurium and S. thompson were dominant types for serotyping in the 221 Salmonella strains, and 221 strains were widely distributed in 46 serotypes, the serotype distribution was more extensive; dairy and dairy products and meat and meat products were main suspicious etiological foods types caused by Salmonella. For drug susceptibility test of 11 kinds of antibiotics, the susceptibility of Salmonella to Cefoxitin, Cefotaxime, Chloramphenicol and Trimethoprim/Sulfamethoxazole significantly decreased (P<0.05), and that to Ciprofloxacin, Ampicillin, Tetracycline and Ampicillin/Sulbactam decreased significantly (P<0.01); only that to Ciprofloxacin, Nalidixic acid and Gentamicin decreased insignificantly (P<0.05). Relevant departments should strengthen the meat and meat products market supervision,to make great efforts for control the use of antibiotics, strengthen the active surveillance of Salmonella disease and drug resistance, and to reduce the incidence of foodborne diseases.
