摘要
目的研究儿童化脓性中耳炎主要致病菌的种类及耐药情况,为临床诊断和治疗提供依据。方法对化脓性中耳炎患儿的中耳分泌物进行细菌分离培养鉴定及药物敏感试验。结果227例标本中201例标本检出病原菌,检出率为88.5豫,其中有8例标本检出2株病原菌,共分离出209株病原菌。病原菌主要是革兰氏阳性球菌164株(78.5%),其中金黄色葡萄球菌116株(55.5%)。金黄色葡萄球菌对青霉素G、氨苄西林、红霉素和克林霉素耐药率很高,对利福平、阿莫西林/克拉维酸、环丙沙星、左氧氟沙星、头孢唑啉耐药率低,未发现对万古霉素、奎奴普丁/达福普汀、利奈唑胺耐药的菌株。结论儿童化脓性中耳炎的主要致病菌是金黄色葡萄球菌。临床医生应根据药敏结果合理使用抗生素。
Objective To find the major types of pathogens in suppurative otitis media in children and analyze the drug resistance to provide a reference for rational clinical use of biotics.Methods The middle ear secretions from children with suppurative otitis media were cultured and the main pathogenic bacteria were isolated,and the susceptibility to antibiotics were carried out.Results 209 pathogens were isolated from 201 specimens in a total of 227 samples.The positive detection rate was 88.5%.There were 8 cases in which two pathogens were isolated.164 cases of Gram-positive cocci were isolated(78.5%),of which 116 Staphylococcus aureus were detected(55.5%).Staphylococcus aureus strains showed high resistance rate to penicillin G,ampicil in,erythromycin and clindamycin and low resistance rate to rifampin,amoxicil in/clavulanic acid,ciprofloxacin,levofloxacin,cefazolin and no resistance to vancomycin,quinupristin/dalfopristin,linezolid.Conclusion The major bacterium stains in suppurative otitis media of chilidren was staphylococcus aureus.The rational use of antibiotics should be ensured according to the antibiotics susceptibility results.
