摘　　要：目的:了解我院儿童下呼吸道标本分离病原菌分布对常见抗菌药物的耐药性。方法:收集我院2014年儿童呼吸道标本,通过培养和抗菌药物敏感性和耐药性试验,对结果进行统计分析。结果:2 051份标本分离病原菌283株,主要为流感嗜血杆菌(占58.30%)、肺炎链球菌(占20.14%)和卡他莫拉菌(占18.73%)。药敏试验显示流感嗜血杆菌和卡他莫拉菌产β-内酰胺酶阳性率分别为41.8%和100.0%,青霉素耐药的肺炎链球菌检出率为3.8%。结论:流感嗜血杆菌、肺炎链球菌和卡他莫拉菌是引起我院2014年儿童呼吸道感染的主要病原菌,提示定期分离病原菌并进行耐药性监测统计有助于及时了解其耐药性的变迁,起到监督、管理及指导对儿童抗菌药物合理应用的作用。Objective： To investigate the drug resistance and distribtion of the bacterial pathogen isolated from pediatric respiratory samples. Methods： Analysed the bacterial pathogen distribtion and antibiotic resistance of pediatric respiratory specimens strains in 2014. Results： In the pediatric respiratory specimens strains,the main isolated specimens strains were Haemophilus influenzae（ 58. 30%）,Streptococcus pneumoniae（ 20. 14%）,Branhamella catarrhali（ 18. 73%）. Drug susceptibility test results showed that：. Influenzae and Branhamella catarrhali producing beta lactamase positive rate were 41. 8% and 100. 0%respectively,and streptococcus pneumonia PRSP detection rate was 3. 8%. Conclusion： Haemophilus influenzae,Streptococcus pneumonia and moraxella catarrhalis were the main sources of respiratory infection among children. Regular surveillance of the isolated pathogens resistance from the pediatric respiratory tract could help us to understand its resistance changes,it would play an active role in strengthening the supervision and management of rational use of antibiotics in children.
