【摘要】：目的：本课题的研究目的是通过调查四川省甘孜藏族自治州藏族中老年人群结膜囊菌群分布,获得其常见眼表菌群资料,为常见眼表感染性疾病诊治提供微生物学,流行病学依据。方法：整体抽取四川省甘孜藏族自治州康定县姑咱镇和九龙县呷尔镇40岁以上的藏族中老年人群145名(290眼)做刮取下睑结膜囊分泌物,接种于血琼脂平板,培养48小时后进行细菌分离鉴定。结果：290眼中结膜囊细菌培养阳性147眼,培养阳性率50.7%。培养出菌株160株,其中以表皮葡萄球菌最多,共76株,占47.5%,棒状杆菌43株,占26.9%,二者共占74.4%。藏族中老年人群中男性结膜囊细菌阳性率52.9%(73/138),女性结膜囊细菌阳性率48.7%(74/152)，，男性与女性相比结膜囊细菌培养阳性率差异没有统计学意义(χ2=0.514,P=0.473)。所检查的藏族中老年人群阳性眼数147眼,其中康定县姑咱镇65眼,阳性率53.28%；九龙县呷尔镇82眼,阳性率48.81%,经统计学分析,二者的差异没有统计学意义(χ2=0.565 P=0.452),提示不同地区的藏族中老年人群其结膜囊细菌阳性率与地区无关。随年龄增加结膜囊细菌阳性率有增加趋势,80岁以上组阳性率明显增高(4/4,100%),经统计学检验差异有统计学意义(χ2=9.591, P=0.048)。结论：多数藏族中老年人结膜囊带菌,其中以表皮葡萄球菌、棒状杆菌为优势菌种。其细菌阳性率无性别及地区上的差异。藏族中老年人结膜囊细菌阳性率随着年龄的增加,其结膜囊细菌有增加的趋势。
[Abstract]:Objective: to investigate the distribution of bacterial flora of conjunctival sac in the middle and old Tibetan population in Ganzi Tibetan Autonomous Prefecture of Sichuan Province, and to obtain the data of common ocular surface flora, and to provide microbiology for the diagnosis and treatment of common ocular surface infectious diseases. Epidemiological evidence. Methods: 145 middle and old Tibetan people over 40 years old in Kangding County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, were collected and 290 eyes of middle and old Tibetan population were scraped and inoculated into blood Agar plate, and the secretion of lower eyelid conjunctival sac was taken out from 145 middle and old Tibetan people over 40 years old in Jiulong County, Sichuan Province. After 48 hours of culture, the bacteria were isolated and identified. Results the positive rate of bacterial culture in conjunctival sac was 50.70.160 strains were obtained, of which 76 strains were Staphylococcus epidermidis (47.5%) and 43 strains were Corynebacterium. The positive rate of conjunctival sac bacteria in males and females was 52.9 / 138and 48.7 / 152respectively. There was no significant difference between male and female in conjunctival sac bacteria culture (蠂 2 0.514 P 0. 473). The number of positive eyes in the middle and old age group was 147, Of these, 65 eyes (53.28%) were positive in Gus Town, Kangding County, and 82 eyes (48.81%) in Guer Town, Jiulong County, with a statistical analysis. There was no significant difference between the two groups (蠂 ~ 2 ~ 2 ~ (0.565) P ~ (0.452A)), suggesting that the bacterial positive rate of conjunctival sac in the middle and old Tibetan population in different areas was not related to the region. The positive rate of conjunctival sac bacteria increased with the increase of age. The difference was statistically significant (蠂 2 9.591, P < 0.048). Conclusion: the bacterial positive rate of conjunctival sac in most Tibetan elderly people is not different in sex and region, among which Staphylococcus epidermidis and Corynebacterium corydalis are dominant. The bacterial positive rate of conjunctival sac in middle and old Tibetan people increases with age. The bacteria of conjunctival sac increased.
