Repression of the virulence of Yersinia pestis by an F' plasmid

R M Zsigray et al. Infect Immun. 1983 Feb.

Abstract

An F-lac plasmid from Escherichia coli was transferred to virulent Yersinia pestis, resulting in the repression of virulence. The Y. pestis F-lac clones retained all of the known virulence traits but were avirulent and calcium independent. Every lac segregant derived from the F-lac clones was fully virulent and calcium dependent.
