Abstract:
Objective:To analyze the situation of intestinal bacterial infections and drug resistance in children,and provide reference for the rational use of drugs in the treatment of bacterial enteritis.Methods:We collected cases of diarrhea in children admitted to the outpatient and inpatient departments of Kunming Children's Hospital from January 2014 to December 2022,whose fecal samples was detected pathogenic bacteria.The drug resistance of pathogenic bacteria was analyzed.Results:A total of 10 233 children with diarrhea were tested for fecal samples,and 595 cases of pathogenic bacteria were detected through fecal culture,with a detection rate of 5.8%.Among them,456 cases of Salmonella were detected,accounting for 76.6%.There were 128(21.5%) cases of Shigella genus,of which Shigella flexneri was the main subset(58.6%).The distribution of departments was most common in the gastroenterology department,followed by the infectious disease wards.The seasonal distribution of bacterial enteritis showed that the incidence was high in summer and autumn.Infants and young children under three years old was found have the highest incidence.The drug sensitivity results showed that Salmonella and Shigella had high resistance to penicillin and aminoglycosides,and were highly sensitive to amoxicillin/clavulanic acid,quinolones,and carbapenems; Cephalosporins had good antibacterial activity against Salmonella,with a resistance rate of 12.9% to 32.7%.However,the overall resistance rate of Salmonella to ceftriaxone and ceftazidime was on the rise.Cefotaxime and cefepime had good antibacterial activity against Shigella,but Shigella had a high resistance rate of 95.0% to ceftriaxone.Conclusion:Salmonella is the main pathogen causing bacterial diarrhea in Kunming region,with the highest incidence in infants and young children under the age of three.The resistance rate of Salmonella to ceftriaxone is on the rise,and it is highly sensitive to amoxicillin/clavulanic acid,quinolones,and carbapenems.This can provide local medication references for primary clinical pediatricians when they cannot obtain the results of bacterial culture drug sensitivity.
