Animal model experiments involving bacterial diseases typically employ assays such as enumerating pathogenic cells by counting colony-forming units (CFU) or identifying and quantifying their proteins or nucleic acids. These assays are labor intensive and require the removal of tissues. Consequently, there is a loss of the contextual influences that were present in the living animal. Rapid
