Abstract:
Objective:To investigate the pathogens and drug resistance of bacterial enteritis in children, analyze the clinical characteristics of bacterial enteritis in children, and provide basis for clinical diagnosis and treatment.Methods:The fecal culture strain and drug sensitivity of patients with bacterial enteritis admitted to our hospital from January 2016 to December 2020 were analyzed and summarized, and the clinical characteristics of patients who were infected by Salmonella and Escherichia coli were compared.Results:There were a total of 173 patients, aged from 21 days to 15 years, with a median age of 2.00(1.10, 3.54)years.Bacterial enteritis was most likely to occur in summer and autumn, and the incidence rate was 40.5% and 29.5%, respectively.One hundreds and seventy-three strains of bacteria were cultured in feces, including 148 strains of Salmonella(85.5%), 18 strains of Escherichia coli(10.4%), five strains of Staphylococcus aureus and two strains of Shigella.One hundreds and one of 141 patients who were infected with Salmonella were detected for leukocytes of in feces(71.6%), and four of 16 patients with Escherichia coli were detected for leukocytes(25.0%). The difference was significant( χ2=14.1, P<0.001). Eighty-eight of 113 patients(77.9%) who were infected by Salmonella with increased CRP(CRP>8 mg/L)and the proportion in Escherichia coli infection cases was 6/13(46.2%). There was significant difference( χ2=4.63, P=0.03). The drug sensitivity of Salmonella and Escherichia coli was summarized.There was no carbapenem resistant strain cultured; The sensitivity to piperacillin/tazobactam and cefoperazone/sulbactam was higher than 85%; The sensitivity to cefepime, ceftazidimeand ceftriaxone was higher than 75%; The sensitivity to ampicillin was lower than 30%, and the sensitivity to quinolones was between 20%-40%. Conclusion:Children aged 1-3 years are prone to bacterial enteritis in summer and autumn.The most common pathogens causing bacterial enteritis are Salmonella and Escherichia coli.White blood cells are more easily detected in feces of patients with Salmonella infection, and the increase rate of C-reactive protein in peripheral blood is higher.Patients with bacterial enteritis are recommended to use the third-generation cephalosporins and aforementioned antibiotics and piperacillin/tazobactam for empirical treatment.The sensitivity to quinolones is reduced, and may not be suitable for clinical application.
