Strains and colonization methodology
| Species | Strain Designation | Inoculum concentration (CFU/mL) | Inoculation duration (hours) | Number of replicates per experiment | Number of experiments completed | Colonization on un-patterned controls (Average log 10 (CFU) across experiments) | Colonization on Micro-patterned samples (Average log 10 (CFU) across experiments) | Repeatability of control colonization (repeatability standard deviation) |
