Abstract

A total of 159 Y. pestis strains isolated in different geographical regions of China have been studied. Y. pestis isolated in the majority of natural foci of plague in China carry plasmids with molecular weights of 6, 13, 15 and 63 MD. One isolated strain has been found to carry plasmid with a molecular weight of 36 MD. Only a few strains have no plasmids with molecular weights of 6 and 45 MD. In certain geographical zones strains carrying large plasmids of 52 and 92 MD have been detected.

摘要

对从中国不同地理区域分离出的总共159株鼠疫耶尔森氏菌菌株进行了研究。在中国大多数鼠疫自然疫源地分离出的鼠疫耶尔森氏菌携带分子量为6、13、15和63 MD的质粒。已发现一株分离菌株携带分子量为36 MD的质粒。只有少数菌株没有分子量为6和45 MD的质粒。在某些地理区域检测到携带52和92 MD大质粒的菌株。
