为了解西藏土壤卫生学及未来战争中造成经土壤感染的有关需氧或兼性厌氧的细菌类型，作者对拉萨、亚东、错那三地区采土样３０份作卫生细菌学调查。细菌总数为０．０２～８．２０×１０６／ｇ，平均１．３５×１０６／ｇ，大肠菌群数大于２３８０００的占８３．８３％（２５／３０），从院内菜地向山坡延伸采土１５份，细菌总数呈逐步降低趋势，８．３２×１０６减至１．１０×１０５／ｇ。１３２株细胞鉴定结果为肠杆菌科６８株（其中志贺氏一株，沙门氏４株），假单胞菌属３４株（含绿脓杆菌１３株），肠球菌属１７株，其它１３株。结论为与创伤感染有关的革兰氏阴性杆菌、大肠埃希氏菌和聚团肠杆菌为主要菌种，绿脓杆菌和嗜麦芽假单胞菌比例也较高，为研究造成创伤感染的主要菌种提供科学依据。
To understand the soil-borne diseases in Tibet and the types of bacteria associated with aerobic or facultative anaerobic infections caused by soil-borne diseases in the future, the authors conducted a sanitary bacteriological survey of 30 soil-taking samples from Lhasa, Yadong and Wakazu. The total number of bacteria ranged from 0.02 to 8.20 × 106 / g with an average of 1.35 × 106 / g and 83.83% (25/30) with more than 238000 of coliform bacteria. Soil 15, the total number of bacteria showed a gradual downward trend, 8.32 × 106 reduced to 1.10 × 105 / g. The results of 132 cell strains were identified as Enterobacteriaceae (68 strains), including 1 strain of Shigella and 4 strains of Salmonella, 34 strains of Pseudomonas (13 strains of Pseudomonas), 17 strains of Enterococcus and 13 strains of other strains . CONCLUSIONS: Gram-negative bacilli, Escherichia coli and Enterobacter agglomerans related to traumatic infections are the main strains, and the ratio of Pseudomonas aeruginosa and Pseudomonas aeruginosa is also high. In order to study the main causes of traumatic infections Species provide a scientific basis.
