Comparison of pLuxMC1-3 colony forming units and bioluminescence from murine GIT samples nine days post-inoculation. Comparison of B. breve UCC2003 pLuxMC derivatives recovered from (a) the caecum; (b) the large intestine and (c) the small intestine, each set of data is representative of the average values from three mice per group. The BLU (bioluminescence counts in photons per second) represented in grey refers to the bioluminescence recorded from the intact tissue sections upon excision 9 days post-inoculation and immediately prior to homogenization. The black bar is the average CFU (colony forming units) per ml of homogenized tissue sample.
