Figure 1From: Persistence of colicinogenic Escherichia coli in the mouse gastrointestinal tractColonization of the mouse intestine by colicin producing E. coli strains. Each point represents the mean CFU (g feces)-1 determined for two mice in each of two cages. Bars represent the standard error of the log10 for each point. The number of cells measured at day 112 for the colicin free strain falls below the limit of detection determined at 102 CFU (g feces)-1.Back to article page
