TABLE 2.
Relative colonization abilitiesa of V. fischeri strains carrying antibiotic resistance
Colonization ability was measured during competition with the parent wild-type strain ES114.
RCI, percentage of a given strain in the light organ divided by percentage of that strain in the inoculum at 24 or 48 h postinoculation.
ND, not determined.
The ability to colonize the light organ was significantly less than that of wild-type V. fischeri (P < 0.05).
