摘要
目的了解彝族与汉族中老年人结膜囊细菌分布情况。方法整群抽取四川省甘孜州九龙县两个彝族乡聚居点的中老年彝族人群136人(272眼),康定县和九龙县汉族聚居地173人(346眼)取结膜囊分泌物进行细菌培养、分离鉴定。比较彝族与汉族人群结膜囊细菌的情况。结果彝族人结膜囊细菌培养阳性率(69.9%)较汉族(60.4%)高,差异有统计学意义(x2=5.942P=0.015)。彝族和汉族受检人结膜囊细菌培养阳性的眼中多数为单一菌种,少数为多种菌种,但两个民族多种菌同时存在的构成比差异有统计学意义(x2=10.694P=0.001),汉族结膜囊多种细菌共存者(11.0%)较彝族多;彝族和汉族结膜囊的优势菌群均为表皮葡萄球菌和棒状杆菌。彝族结膜囊表皮葡萄球菌的阳性率为37.4%,汉族为33.2%,差异无统计学意义(x2=0.924P=0.336);彝族结膜囊中棒状杆菌的阳性率为32.1%,汉族人群为17.3%;差异有统计学意义(x2=15.296P=0.000)。结论四川甘孜州藏区彝族中老年人结膜囊细菌培养阳性率较汉族中老年人高,彝族和汉族中老年人结膜囊的细菌多数为单一菌种,少数为多种菌种共存,汉族多种细菌共存较彝族多,两民族结膜囊的优势菌群均为表皮葡萄球菌和棒状杆菌,但彝族结膜囊的棒状杆菌阳性率较汉族高。
Objective Present survey was to obtain the data about bacterial species in conjunctival sac in Yi nationality population and ttan nationality population aged 40 years or older. Methods This sur- vey study was performed as the standardized training and protocol. A total of 272 eyes of 136 individuals from Yi nationality and 346 eyes of 173 subjects from Han nationality in Ganzi Autonomous Prefecture re- ceived questionnaire survey and ophthalmological examination. The secretion of the inferior palpebral con- junctival sac was embrocated and inoculated on blood plate for 48 -72 hours. The bacteria was separated and identified. Results The positive rate of the bacteria cultivation of Yi nationality(69.9% ) was statisti- cally higher than that of Han people (60.4. % ) ( X2 --5. 942 P = 0. 015 ). There was statistical difference in the multiple bacterial species between the two groups (X2 = 10. 694 P = 0. 001 ), and in the positive rate of corynbaccterium between the two groups(x2 = 15. 296 P = 0.000). There was no difference in the positive rate of staphylococcus epidemics in the two nationality (X2 = 0. 924 P = O. 336). Conclusion The positive rate of the bacteria cultivation of Yi nationality was statistically higher than that of Han people. The simple bacterial species was found in majority people in the two groups. The positive rate of multiple bacterial strains coexistence was more in Han nationality. The predominant bacterias were staphylococcus epidemics and corynbaccterium in Yi nationality and Han nationality, but the positive rate of corynbaccterium in Yi hationality was higher than that in Han nationality.
