广州地区正常人结膜囊真菌和细菌调查

SURVEY OF FUNGI AND BACTERINUM OF THE CONJUNCTIVAL SAC IN GUANGZHOU AREA

本文报道我国南方正常结膜囊真菌培养178眼,细菌培养137眼.真菌培养阳性者:农民组25%,环卫工人组11.1%,城市普通人群8.8%;细菌培养阳性者:农民组71.9%,环卫工人组80.6%,城市普通人群为23.2%.此外眼部长期用激素者真菌检出率为9.7%,细菌检出率为30%.被检出的真菌株以曲霉菌属和青霉菌属占最多;细菌以葡萄球菌和肺炎球菌占最多.这与临床眼部常见感染的病原菌相类似.虽然结膜囊分离出的菌株,多数为非致病菌或条件致病菌,但在机会感染增加的今天,应强调结膜囊的消毒处理,或条件致病菌,加强眼部感染的预防.

This paper presents the results of fungal cul-ture from healthy conjunctival sac in 178 eyes.The rate ofpositive culture of the fungi was 25% in farmers,11.1% in cleaners,and 8.8% in city residents respectively,culture foraerobic was carried out in the samples from conjunctival sacsof 137 eyes.The rate of positive culture was 71.9% infarmers,80.6% in cleaners,and 23.2% in city residentsrespectively.On the other hand,the rate of funsal positiveculture was 9.7% and that of aerobic was 30% in the pa-tients managed with steriod eyedrops for more than one mon-th.The aspergillus and penicillum were the most commonlyseen species among the isolated funsal strain,whereas thestaphylococci and streptococcus pneumonia were the mostcommon among the isolated aerobic.The results run parallelto the fact that the main pathogens of ocular infection seenclinically are fungi and aerobics.The authors emphasize thatthe conjunctival sac should be disinfected to prevent infectionscaused by opportunitic pathogens.
