Scattergraph of viable bacteria recovered from organs of BALB/c mice at 8, 24, 72, 168, or 240 h postinfection. Organs from which bacteria were recovered include the blood (A), liver (B), kidney (C), spleen (D), and heart (E). Mice were infected intravenously with either E. faecalis MGH-2 (red circles) or JH2-2 (blue circles). Each circle represents the number of viable bacteria (CFU per organ or CFU per milliliter of blood) in an individual infected mouse. In some cases, where the numbers of viable bacteria in organs from different mice are almost identical, the values are not visible as individual circles. Circles below 100 on the y axis represent values below the level of detection. The numbers of mice infected with MGH-2 or JH2-2 and necropsied at each time point are given in parentheses (MGH-2/JH2-2) above the graph.
