本实验以模拟的方法，采集不同地区、不同类型的土壤，人为用炭疽杆菌污染，在不同条件下观察该菌形成芽孢数量的变化。结果证实土壤的类型与芽孢的形成数量无明显关系，炭疽杆菌在土壤中保存时，随着时间延长，形成芽孢的比率并无明显增加，但数量有所增长，说明土壤环境在一定程度上支持炭疽杆菌繁殖。特别是在土壤中加入新鲜动物血液时，芽孢数量明显增多，土壤的温度和湿度平衡对芽孢形成影响最大，符合炭疽的流行病学规律，提示在炭疽的监测与控制中，我们应当考虑到炭疽杆菌的这种特征，以便采取更有力的措施。
In this experiment, a simulated method was used to collect soil in different regions and different types. Anthrax was used to pollute human beings. The changes of the number of spores were observed under different conditions. The results confirmed that there was no significant relationship between the soil types and the number of spores. When Bacillus anthracis was preserved in soil, the rate of sporulation did not increase significantly with the increase of the number of spores, indicating that the soil environment supported to a certain extent Bacillus anthracis reproduction. In particular, the addition of fresh animal blood to the soil significantly increased the number of spores, and the balance of temperature and humidity in the soil had the greatest effect on sporulation, which was in line with the epidemiology of anthrax, suggesting that in anthrax monitoring and control we should consider anthrax This feature of bacilli in order to take more forceful measures.
