【摘要】：目的了解金黄色葡萄球菌(SA)在高原枪弹伤组织中增殖情况。方法在拉萨(高原)和重庆(平原)分别将幼猪枪弹致伤,取伤后不同时间挫伤区组织进行细菌学检测;用消毒滤纸片蘸取两地感染分离的SA生理盐水稀释液,在高原相对湿度35%自然干燥一定时间后行体外增殖和存活时间测定。结果SA在高原枪弹伤机体组织中迟缓期时间较平原延长9 h,对数期SA增殖较平原慢;相对湿度35%下体外干燥120 h的SA增殖较未干燥菌慢5 h,在平原,相对湿度80%下SA自然存活(67±7)d;在高原,相对湿度35%下SA自然存活(21±4)d,相对湿度15%下SA自然存活仅(9±2)d。结论SA在高原机体组织中增殖慢,环境干燥是SA在高原枪弹伤组织中增殖迟缓期延长的主要因素之一。
[Abstract]:Objective to understand the proliferation of Staphylococcus aureus (SA) in the high altitude gunshot wound tissue. Methods the young pigs were wounded in Lhasa (plateau) and Chongqing (plain), and the tissue of the contusion area was detected at different time after the injury. The disinfectant filter paper was dipped into the SA saline diluents separated by two ground infections, and the relative humidity of the plateau was 35% from the plateau. However, after a certain period of drying, the proliferation and survival time were measured in vitro. Results the delayed period of SA was 9 h longer than that in the plain, and the proliferation of SA was slower in logarithmic phase than that in the plain. The SA proliferation of 120 h in the relative humidity 35% was 5 h slower than that of the non dry bacteria, and in the plain, the phase to the humidity 80% SA survived (67 + 7) d; at the plateau, the phase was on the plateau. The natural survival (21 + 4) d of SA under 35% humidity and natural survival (9 + 2) d. under relative humidity (15%) conclusion SA is slow to proliferate in the body tissues of the plateau, and the dry environment is one of the main factors that prolong the delay period of the proliferation of SA in the high altitude gunshot wound.
