Figure 7. Plaque assay with S. flexnerioxyR and soxRS mutants.
Confluent Henle cell monolayers were infected with 104 bacteria per 35-mm diameter plate and the diameter of the plaques were measured after 3 days. The data presented are the means of at least three experiments, and the standard deviations of the means are indicated. The difference between SM100 and UR025 was significant (p<0.05).
