目的鉴定塞拉利昂农村人群正常结膜植物群，并比较发展中国家与发达国家正常眼植物群。方法对塞拉利昂Masungbo市276名健康居民右眼结膜拭子进行微生物生长分析。结果健康眼结膜拭子中最常见的病原菌为凝固酶阴性葡萄球菌（28.6%）、真菌（26.0%）、金黄色葡萄球菌（19.9%）、革兰氏阴性菌（9.8%）、诺卡氏菌（6.5%）、铜绿假单胞菌（6.2%）。结论：塞拉利昂农村人群健康眼真菌和细菌定植的患病率较高。常驻正常植物群与眼部感染的病因可能存在关系。
Purpose To identify the normal conjunctival flora in a rural population in Sierra Leone and compare the normal ocular flora of a developing country with that of the developed world. Methods Conjunctival swabs obtained from healthy right eyes of 276 residents of Masungbo, Sierra Leone, were analyzed for growth of microorganisms. Results The most commonly isolated organisms from conjunctival swabs of healthy eyes were coagulase-negative Staphylococcus (28.6%), fungus (26.0%), Staphylococcus aureus (19.9%), Gram negatives other than Pseudomonas/Haemophilus (9.8%), Nocardia/Actinomyces (6.5%), and Pseudomonas aeruginosa (6.2%). Conclusions There is a high prevalence of fungal and bacterial colonization of healthy eyes in a rural population of Sierra Leone. A relationship may exist between resident normal flora and the etiology of ocular infections.
