MC58ΔluxS is defective for bacteremic infection compared with the parental strain, MC58. This defect is restored by supplying a single, intact copy of luxS in trans to MC58ΔluxS (MC58ΔluxSEct); the difference in the virulences of MC58ΔluxS and MC58ΔluxSEct is highly significant (P < 0.001). The CI is the proportion of the strains in the bloodstream 21 to 24 h following infection with a 1:1 ratio of the strains.
