Salmonella typhimurium LT7 and LT2 strains carrying the imp operon on colIa

W H Koch et al. J Bacteriol. 1995 Apr.

Abstract

The imp operon is carried on a transmissible plasmid, ColIa, in original isolates of Salmonella typhimurium LT7. LT2 strain recipients of F' factors from LT7 strains harboring ColIa can acquire ColIa and imp under nonselective conditions. Thus, S. typhimurium LT2 strains that have received plasmids by conjugal transfer from LT7 strains might be inadvertently harboring ColI factors.
