Figure 3. Isolation of Salmonella from the organs.

BALB/c mice were infected by different Salmonella serovars through oral infection. At 1, 3, 5, and 6 day(s) post-infection, mice were sacrificed. Spleen (A) and liver (B) were grounded and plated on the SS agar plates. Mice were co-infected with SL1344 and SC-B67 (C). At 5 days post infection, both serovars were recovered from the spleen and liver, and analyzed by CI as described in the text. **p < 0.01.
