Objective To explore the pathogenic microbial detection results and drug susceptibility results of children with bacterial diarrhea after the collection of stool samples. Methods From April 2020 to June 2023,170 children with bacterial diarrhea participated in the study. The family members were informed about the study, and assisted the children to complete the collection of stool specimens. All the specimens were sent to the laboratory for pathogen culture, counted the distribution of pathogens, and analyzed the drug resistance of pathogens. Results 170 stool samples isolated 122 pathogenic strains, The detection rate of gram-negative bacteria was 76.23%, mainly Salmonella (27.87%), diarrheagenic Escherichia coli (21.31%), Shigella (21.31%); The detection rate of gram-positive bacteria was 23.77%, mainly Staphylococcus aureus (22.95%); Most resistance to tetracycline (41.18%), ciprofloxacin (38.24%), ampicillin (35.29%), The greatest resistance to ciprofloxacin (46.15%), tetracycline (38.46%), of ciprofloxacin (53.85%), tetracycline (46.15%), Staphylococcus aureus had to clindamycin (53.57%) and penicillin (53.57%). Conclusion Salmonella, Escherichia coli, Shigella and Staphylococcus aureus are the main causes of bacterial diarrhea in children. The drug resistance and the choice of sensitive drugs are conducive to the early recovery of children.
