Summary of mean time to death and survival of rabbits in two sequential combination treatment studies.

1Survival rates for each group at day 30 post exposure.2Time-to-death and overall survival rates between groups by pairwise Log-rank test. NA- Log-rank test was not possible due to no deaths occurred in either group.3A total of 9 animals were exposed to anthrax spores but two were excluded from survival analysis due to death related to gavage error. - Not determined due to lack of sufficient number of deaths.4Survival rates for each group at day 32 post exposure.5Comparing overall-survival between the groups. *Two animals from 72 hours and one animal from 84 hours group were non bacteremic at the time of treatment.Summary of mean time to death and survival of rabbits in two sequential combination treatment studies.
