烧伤病房病原菌的构成和分布

目的：对烧伤病房病原菌分布特征、耐药性的变化趋势进行分析。方法：对近５年本院烧伤病房病原菌分布情况进行统计分析。结果：金葡球菌相对集中分布在春季，而铜绿假单胞菌在四服的分布较为平均，其它细菌的分布则相对集中于夏季。革兰阳性球菌和铜绿假单胞菌在老年患者中构成比较高，而肠杆菌和沙雷菌属在１０岁以下的儿童构成比较高。主要病原菌在不同性别的分布差异不大。结论：了解病原菌构成的变化和分布特征，对于加强感染防治工作的针对性具有重要意义。

Constitution and distribution of pathogens in a burn unit

Objective:To investigate the distribution and constitution of pathogens in a burn unit.Methods:The identification data of bacteria isolated from our burn unit in a 5 year period were analyzed in terms of years, seasons, ages and gender.Results:The constituent ratio of S. aureus was gradually increased and ranked the first in infectious pathogens of the burn unit. Staphylococcus was comparatively prevalent in spring, P. aeruginosa distributed evenly in four seasons, and other bacteria were pervalent in the summer. Gram positive cocci and P. aeruginosa were predominant in old patients, Enterobacter and Serratia were frequenters in children, and the constituent ratio of some bacteria in female were much higher than that in male in certain period.Conclusion:It is important to know the constitutional changes and distribution characters of pathogens for a better sanitation, infection prophylaxis and treatment in burn units.
