云南鼠疫流行历史悠久,80年代家鼠鼠疫复燃,90年代鼠疫在我省形成了沿中缅边境,由滇西向滇西南,由边向内扩大的局面。自鼠疫复燃以来,先后在缅甸境内缅方送检材料中多次检出鼠疫菌。为了解检出菌株的生物学特性,我们将分离的鼠疫菌进行了较全面的实验室检查,现将结果报道如下。 The spread of the plague in Yunnan Province has a long history. The plague of House-pests of the 1980s revived. The plague of the 1990s formed a situation of expanding inwards along the Sino-Burmese border from Yunnan to Western Yunnan in the 1990s. Since the plague rekindle, it has repeatedly detected Yersinia pestis in Myanmar materials in Myanmar. In order to find out the biological characteristics of the strains, we conducted a more comprehensive laboratory test on the isolated Yersinia pestis. The results are reported as follows.
