Abstract 【Objective】To analyze the distribution and drug resistance of bacteria in children with community-acquired pneumonia in our hospital. 【Methods】A retrospective analysis was conducted on the relevant data of hospitalized children with community-acquired pneumonia admitted to the pediatric department of our hospital from January 2017 to December 2021, and the bacterial infection status of the children was analyzed. 【Results】 Out of 7839 sputum samples from children with community-acquired pneumonia, a total of 1753 cases were bacterial positive and qualified, with a total positive detection rate of 22.36%. The main bacteria were Streptococcus pneumoniae(10.14%), Haemophilus influenzae(7.54%), Moraxella catarrhalis(4.38%), and Staphylococcus aureus(2.70%). The positive rates of sputum culture in children with different years, seasons, and ages were compared, and the differences were statistically significant(P<0.01). The detection rates of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in different seasons were compared, and the differences were statistically significant(P<0.01). The detection rates of Streptococcus pneumoniae, Moraxella catarrhalis, and Staphylococcus aureus in children of different ages were compared, and the differences were statistically significant(P<0.01). Streptococcus pneumoniae has a high resistance rate to clindamycin, erythromycin, and tetracycline. Staphylococcus aureus had a high resistance rate to penicillin and erythromycin. The positive rates of β-lactamases produced by Haemophilus influenzae and Moraxella catarrhalis were 78.85% and 94.15%, respectively. 【Conclusion】The main bacteria detected in children with community-acquired pneumonia are Streptococcus pneumoniae, and the detection rates of each bacterium vary in different years, seasons, and ages.
