DNA Analysis of the Bacterial Pathogen in the Yellow Sand

敦煌、奈曼等地新开发农田的沙尘或黄沙主要受人类活动的影响。通过真实的时间PCR分析的DNA判断方法，发现在冲绳、福冈和筑波采样的黄沙上附着口蹄疫病毒的可能性。黄沙矿物主要由盐类和次生产物组成。发现硫酸盐的含水矿物和人类起源的N在一个很好的表面。黄砂的运移环境表明，黄砂上石膏是在接近中性的pH值和很高的湿度条件下产生的。2010年春季在宫崎发现的牛口蹄疫第一次发病可能是由来自中国甘肃省的黄沙引起的，第二次传播是基于当地的地面风。

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.
