摘　　要：目的:分析婴幼儿泪囊炎的致病菌分布和耐药性,指导临床合理用药。方法:选取2013年1月-2014年5月笔者所在医院眼科门诊诊断为婴幼儿泪囊炎的患儿共136例,挤压泪囊部反流的脓汁作为标本送检,进行细菌培养及药物敏感性分析。结果:136份标本,113份培养阳性,共检出113株病原菌,检出率83.1%,以革兰阴性杆菌为主,但检出率最高的病原菌为金黄色葡萄球菌(17株,15.0%),MRSA菌株3株,其次为表皮葡萄球菌(13株,11.5%),MRCo NS菌株3株;未检出真菌。药敏方面,所有菌种对青霉素类耐药率较高,而对氨基糖苷类和喹诺酮类耐药率较低。结论:婴幼儿泪囊炎病原菌以金黄色葡萄球菌、表皮葡萄球菌、流感嗜血杆菌、奈瑟氏菌属为主;大多数菌株对氨基糖苷类和喹诺酮类耐药率较低,对青霉素类耐药率较高。Objective：To analyze the distribution and drug resistance of infant dacryocystitis pathogens so that to provide reference for clinical the use of antimicrobial agent.Method：Selected from January 2013 to May 2014 in our hospital eye clinic patients diagnosed with a total of 136 cases of infant dacryocystitis,squeeze the pus sac Ministry reflux as specimens sent for bacterial culture and drug susceptibility analysis.Result：A total of 113 specimens were culturepositive which detected in 113 strains of pathogens,detection rate was 83.1%,Gram-negative bacilli was dominant,but the highest detection rate pathogen was Staphylococcus aureus（17 cases,15.0%）,three for MRSA strains,followed by Staphylococcus epidermidis（13 cases,11.5%）,three for MRCo NS strains.Not detected fungi.Susceptibility,all strains were highly resistant to penicillin,but resistance to aminoglycosides and fluoroquinolones lower rates.Conclusion：Infant dacryocystitis pathogen distributed mainly with Staphylococcus aureus,Staphylococcus epidermidis,Haemophilus influenzae,Neisseria based.Most strains have a lower resistant rate to aminoglycosides and fluoroquinolones and high rate to penicillin-resistant.
