DNA Analysis of the Bacterial Pathogen in the Yellow Sand

敦煌和乃满地区新开发农田的沙尘和黄沙受人类活动的影响。通过实时PCR分析的DNA判断方法，发现冲绳、福冈和筑波三地黄沙上口蹄疫病毒的粘附概率较高。黄砂的矿物主要由盐类和二次产物组成。在精细的表面上发现了硫酸盐水合矿物和人为氮源。黄沙的迁移环境表明，黄沙上的石膏是在接近中性的pH值和极高的湿度条件下生成的。2010年春季在宫崎县发现的第一次牛口蹄疫疫情可能是由中国甘肃运来的黄沙引起的，第二次疫情是根据当地的地面风传播的。

Dust or yellow sand of new developed agricultural field is affected by human activity at Dunhuang and Naiman in China. By DNA judgment method of real time PCR analysis, it was found that the probability of foot-and-mouth disease virus adhered on yellow sand sampled at Okinawa, Fukuoka and Tsukuba. The mineral of yellow sand is mainly composed by the salts and the second product. Hydrous mineral of sulphate was found and human originated N on a fine surface. The transport environment of yellow sand was shown that gypsum on yellow sand was produced under the conditions of nearly neutral pH and very high humidity. The first attack of foot-and-mouth disease of cattle found at Miyazaki in spring, 2010 is presumably originated by yellow sand transported from Gansu Province, China and the second spread is based on the local surface wind.
