Statistical groups (within each day post inoculation) are denoted with letters, where the difference between groups which do not share a letter are statistically significant with a p of value < 0.05. Abbreviations: BHI = brain heart infusion broth, DPI = days post inoculation, PBS = phosphate buffered saline.
