Abstract：In order to understand the clinical manifestations and etiological characteristics of the rare bacterial type of Salmonella Jangwani infection, and to pinpoint the source of the infection. Phenotypic characteristics of pathogenic bacteria were studied by systematic biochemistry, serology and drug sensitivity test. The diagnosis and treatment of the child were retrospectively reviewed and the patient’s return visit and epidemiological investigation were conducted. Continuous pathogen retrieval was performed on high-risk factors, and PFGE typing was used to trace the source of Salmonella Jangwani from different sources. The pathogens isolated from the blood of the children were identified as Salmonella (id=99.9%) by API 20 E, and the antigen structure was 17∶a∶1.5, which was the Salmonella Jangwani. The results of the investigation showed that this case of hemorrhagic diarrhea, secondary bacteremia infection, pet Brazilian tortoise is a possible source of pollution. In three consecutive pathogen searches, Salmonella Jangwani was detected in four Brazilian tortoise samples. The PFGE and biochemical profiles of strains from different sources were 100% consistent, and the drug resistance spectrum was highly consistent, suggesting that the isolates of the Brazilian tortoise and the isolates of the children were derived from the same clone. Five isolates were sensitive to 25 common antibiotics, resistant to sulfisoxazole, and moderately resistant to tetracycline and cefazolin. The child with bacteremia in this case is the first detected Salmonella Jangwani infection in Jiangsu Province, and the infection is related to the contact of pet Brazilian tortoise.
