pGC1, a self-transmissible lac plasmid that originated in Yersinia enterocolitica 842, is described. This plasmid is freely transmissible between strains of Y. enterocolitica and from such strains to strains of Escherichia coli. The plasmid can also be transferref among G. coli strains and back to Y. enterocolitica, although at a greatly reduced frequency. pGC1 has a molecular weight of about 33.0 x 10(6), has a base composition of about 44 mol% guanine plus cytosine, and is fi-.
