a
Spleens from five mice were extracted at each time point (limit of detection, 5 CFU/spleen).
b
Calculated from recovery on BIN agar and verified by immunofluorescence staining analysis.
c
Combined from CFU counts on MacConkey agar BHIA, and blood agar.
d
Y. pestis could be recovered from only one mouse at this time point.
