Numbers of guinea pigs where L. monocytogenes was recovered from liver and spleen after oral dosage with a 1:1 mixture of un-restricted and oxygen-restricted L. monocytogenes, carrying either of the two different fluorescent labels CFP and YFP. Samples were taken either four or seven days post first dosage. Mean log (CFU/g) designate the mean levels found in animals positive for Listeria in the given organs, followed by standard deviations. | ||||||||
