OBJECTIVES
This study aimed to determine the disinfecting potential of some contact lens solutions used by some university students in Oman.
METHODS
This work was carried out from January to June 2010 in the Department of Microbiology & Immunology, College of Medicine and Health Sciences, Sultan Qaboos University, Oman. Fifty disinfecting solutions, in which contact lenses were disinfected according to the manufacturers' instructions, were collected from the students and plated on various microbiological culture media. Bacterial isolates were identified by API-20E, API-20NE and Phoenix automated systems while fungi were identified by their cultural characteristics and biochemistry.
RESULTS
From 98 isolates, Pseudomonas aeruginosa was 23.5%; Penicillium, 13%; Candida species, 9.2%; coagulase negative staphylococci, 9.2%; Serratia marcescens, 6.1%; Bacillus, 5.1%; Aspergillus flavus, 5.1%; Serratia liquefaciens, Pseudomonas fluorescens, Enterobacter cloacae and Aspergillus niger, 4.1% each; Chryseomonas luteola and Chryseomonas indologenes, 3.1% each; Stenotrophomonas maltophilia, Serratia odorifera, 2.0% each; Enterobacter aerogenes and Klebsiella pneumoniae, 1% each. Most isolates (65%) came from polyhexanide containing solutions.
CONCLUSION
Contact lens disinfecting solutions with the same formulations, but manufactured by different companies, possessed different disinfecting potentials.
目的
本研究旨在确定阿曼一些大学生使用的某些隐形眼镜护理液的消毒潜力。
方法
本研究于2010年1月至6月在阿曼苏丹卡布斯大学医学与健康科学学院微生物学与免疫学系开展。从学生处收集了50种按照制造商说明对隐形眼镜进行消毒的护理液，并接种于各种微生物培养基上。使用API-20E、API-20NE和Phoenix自动化系统鉴定细菌分离株，通过培养特征和生化特性鉴定真菌。
结果
在98株分离株中，铜绿假单胞菌占23.5%；青霉菌占13%；念珠菌属占9.2%；凝固酶阴性葡萄球菌占9.2%；黏质沙雷氏菌占6.1%；芽孢杆菌占5.1%；黄曲霉占5.1%；液化沙雷氏菌、荧光假单胞菌、阴沟肠杆菌和黑曲霉各占4.1%；金黄产碱杆菌和产吲哚金黄杆菌各占3.1%；嗜麦芽窄食单胞菌、气味沙雷氏菌各占2.0%；产气肠杆菌和肺炎克雷伯菌各占1%。大多数分离株（65%）来自含聚己缩胍的护理液。
结论
配方相同但由不同公司生产的隐形眼镜护理液具有不同消毒潜力。
