Abstract: Objective To explore the characteristics of TCM syndromes in convalescent carriers of Salmonella typhimurium enteritis in infants, in order to provide clinical ideas for TCM differential treatment. Methods Relevant investigation and analysis were carried out in the convalescent carriers of Salmonella typhimurium enteritis in infants who were diagnosed and treated from June 2016 to December 2018, and the symptoms and signs of TCM were collected by filling in questionnaires of TCM syndromes, which were summarized and analyzed to make differential typing. Results Totally 40 cases of convalescent carriers of Salmonella typhimurium enteritis in infants were included in the study, whose main TCM symptoms and signs were poor appetite, mucus in stool, abdominal distention, loose stool, pale tongue quality, lean body shape, mental fatigue，and greasy tongue coating, and the TCM syndromes included syndrome of spleen denciency and damp trap（35%）,spleen insufficiency syndrome（20%）,syndrome of deficiency of spleen and stomachqi（20%）,syndrome of deficiencycoldness of spleen and stomach（10%）,syndrome of deficiency of spleen and stomachyin（7.5%） and syndrome of dampness stagnation of Middle Jiao（7.5%）. Conclusion The main pathogenesis of convalescent carriers of Salmonella typhimurium enteritis in infants is consumption due to diarrhea and drug effects, which causes damage to the function of spleen and stomach. The basic principle of treatment is to invigorate spleen, promote digestion and remove dampness by giving full play to the treatment advantages of TCM at multiple levels and links, in order to achieve the goal of eliminating Salmonella typhimurium in intestinal tract.
