TABLE 2.
Proportion of organs infected following gavage administration of strain F6214-1 (ca. 3 × 107 cfu/mouse) compared to the proportion of mice dying when inoculated at a similar dose
| Proportion (%) of mice dyinga | Proportion (%) of organs infected at 72 and 120 h postinoculation in:

|---|---|---|---|
| Liver | Spleen | Conceptus | |
| 4/11 (36%) | 26/38 (68%) | 24/37 (65%) | 13/38 (34%) |
a
The proportion of mice dying was obtained from LD50 measurements. Fisher's exact analysis revealed that none of the infection rates for liver, spleen, and conceptus were necessarily independent of death rate.
