Abstract

Summary

The virulence (expressed as LD50 values) for mice of two mutant strains of , both containing Tn insertions in the resident plasmid, was reduced by 10–10 when infection was by the oral or intravenous or intraperitoneal route. When the plasmid was lost from one of the mutants no further decrease in virulence was observed. Results also suggested that plasmid genes are not involved in the ability of to cross the gut wall.
