R483, an I pilus-determining plasmid previously reported as belonging to a distinct incompatibility group Ibeta, proved to be an atypical Ialpha plasmid; in a growing culture, the degree of inhibition of replication of one Ialpha plasmid by the presence of another was not uniform within the Ialpha group.
R483是一种先前报道属于不同不相容群Iβ的I菌毛决定质粒,结果证明它是一种非典型的Iα质粒;在生长培养物中,Iα质粒组内一种Iα质粒的存在对另一种Iα质粒复制的抑制程度并不一致。
