Intradermal infections of mice.

<p>C57BL/6 female mice (n = 5) were infected intradermally with different strains of <i>F. tularensis</i> in 2 representative experiments. The doses given are the approximate numbers of <i>F. tularensis</i> injected (for real doses see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0034639#s4" target="_blank">Materials and Methods</a>). The number of surviving mice as well as the mean time to death (MTD) and standard deviations are shown. When indicated, spleens were isolated on day 12 p.i and the numbers of CFU/ml determined. NT = not tested.
