Abstract: To study biological and molecular characteristics of Salmonella Jangwani isolated for the first time from an infant in Beijing. Systematic biochemical identification, serotype identification, broth micro-dilution and pulsed-field gel electrophoresis were conducted to identify the strain. The new isolation reflected the serotype diversity of Salmonella. The isolated strain had the phenotypic characteristics of S. Jangwani,and it was sensitive to 15 antibiotics. The infection was associated with pet turtle from foreign country.
