摘要
目的 探讨驻寒区部队秋冬季野外训练期间应激状态下人体上呼吸道正常菌群变化的流行病学特征及发病规律。方法 对某部队士兵野外训练前、中、后分别采集口咽、鼻腔分泌物进行细菌学检查。结果 士兵训练前、中、后 ,咽、鼻腔条件致病菌为训练前 <训练中 <训练后 ,P <0 .0 0 5 ,各组菌群之间差异有显著性 ,G+ 球菌逐渐下降 ,G-杆菌逐渐上升 ,鼻腔中真菌的变化最明显 ,由训练前的 0上升到训练后的 11.14 % ,以毛霉菌和烟曲霉菌为主。
OBJECTIVE To explore the epidemic features and the pathogenesis of bacteriological changes in upper respiratory tract of soldiers who were drilled in stress status during a field exercise in autumn and winter of cold areas. METHODS Secretion was collected for bacterial test from nasal and pharyngeal cavity of soliders who participated military training. RESULTS The amount of opportunistic pathogen from nasal and pharyngeal cavities before training was significantly different from that during and after training (P<0.005). The Gram positive cocci decreased and Gram negative bacilli increased during the examination. The most dramatic change was detected in fungi (especially Aspergillus fumigatus and Mucor corymbifer) of nasal cavity that elevated from nearly zero before training up to 11.14% after training. CONCLUSIONS Flora inbalance is one of the major reasons for the infection of upper respiratory tract under the stress status.
