Function of the largest plasmid of Yersinia pestis was studied. Assay of four strains of highly virulent Y. pestis isolated from different natural sources demonstrated that the characters of endotoxin production, sugar and alcohol fermentation, nitrate reduction as well as requirement in nutrients are mediated by no Y. pestis plasmids. On the contrary, FI and FII antigens are determined by the largest plasmid in some strains and are chromosome-mediated in others. It may well be that the genes for these antigens are comprised within the transposon-like DNA fragment.
对鼠疫耶尔森氏菌最大质粒的功能进行了研究。对从不同自然来源分离出的四株高毒力鼠疫耶尔森氏菌进行的测定表明，内毒素产生、糖和酒精发酵、硝酸盐还原以及营养需求等特性并非由鼠疫耶尔森氏菌质粒介导。相反，FI和FII抗原在某些菌株中由最大质粒决定，而在其他菌株中则由染色体介导。很可能这些抗原的基因包含在转座子样DNA片段中。
