从我国内蒙古、河北和宁夏长爪沙土鼠鼠疫疫源地分离的鼠疫菌株,在含色氨酸各前体产物的限定培基上生长良好,而从新疆精河和乌苏长尾黄鼠鼠疫疫源地分离的菌株,在相同的限定培基上则不生长。根据Trp~-鼠疫菌株利用色氨酸各前体产物的差别,可将分离自我国不同疫源地的色氨酸依赖型鼠疫菌株区别开。 从我国新疆和田昆仑山山地喜马拉雅旱獭疫源地和洛浦的鼠疫患者、云南家鼠疫源地及内蒙古布氏田鼠疫源地分离的不同营养依赖型Glu~-菌株对谷氨酸前体产物的利用亦有差别。
The plague strains isolated from plague foci of Inner Mongolian, Hebei and Ningxia clams have good growth on the limited medium containing the tryptophan precursor products. However, from the plague Strains isolated from the source did not grow on the same defined medium. According to the difference of tryptophan precursor products of Trp ~ - plague strains, the tryptophan-dependent plague strains isolated from different foci of China can be distinguished. From the plague origin of Himalayan origin in Kunlun Mountain, Wotif Mountains, Xinjiang to the plague patients in Luopu, the Yunnan Providence Plaguefarms and the Bradyrhizobium voles in Inner Mongolia, the different nutrient-dependent Glu ~ - strains of glutamate precursor products Use is also different.
