鼠疫菌毒力标准株选育的研究——鼠疫菌毒力标准株P—141的确定

THE RESEARCH FOR THE STRAIN WITH STANDARD VIRULENCE OF Y. PESTIS—THE DETERMINING Y.PESTIS P-141 WITH STANDARD VIRULENCE STRAIN

通过定向选择、培育,建立起了保证鼠疫菌P—141株的种、株性状不变并将其毒力定量地稳定于高水平上的技术系统,而确立其为鼠疫菌毒力标准株。

The technical system has been tablished that can keep the character's species and strain of Y.pestis P-141 stable and retain the quantitative virulence to a high level steadily through directional choice and cultivation. So the strain is regarded as Y.pestis standard virulence strain.
