1、江门地区老年性白内障患者结膜囊带菌状况的调查 【摘要】目的:了解江门地区50岁以上老年性白内障患者结膜囊带菌状况,分析细菌构成和对药物的敏感性。方法:选择2016年6-10月在本院住院的50�q以上的老年性白内障患者707例1414眼,在结膜囊无菌化准备前,采集结膜囊标本做细菌培养及药敏试验。结果:送检1414份标本中,有菌生长106眼,其中91眼有细菌生长,15眼有真菌生长。不同性别、眼别、年龄,结膜囊细菌检出率比较,差异均无统计学意义。不同月份、不同居住地的结膜囊细菌检出率比较,差异均有统计学意义。阳性标本中各菌种的构
2、成比为,G+球菌75.5%,G+杆菌7.5%,G-杆菌1.9%,G-球菌0.9%,真菌14.2%。药物敏感试验结果显示,大多数G+球菌对克林霉素、妥布霉素、万古霉素敏感,对林可霉素和诺氟沙星耐药。整体而言,万古霉素、左氧氟沙星的耐药率较低。结论:江门地区50岁以上老年性白内障患者结膜囊可能带有病原菌,并以G+球菌为主。大多数细菌对万古霉素和耐药的左氧氟沙星敏感。 【关键词】结膜囊;细菌培养;药物敏感试验 InvestigationBacterialSpeciesofConjunctivaSacsofPatientswit
