  • a The bacteria were inoculated in transport medium and were stored at room temperature for the indicated period of time. Each value represents the mean number of bacteria in duplicate samples.

  • b The inoculum was ∼5.5 × 106. The strain was isolated from a wound sample of a patient during the 1998 outbreak along the Ljusnan River in Sweden.

  • c The inoculum was ∼1.5 × 106. The strain was the live vaccine strain F. tularensis LVS.
