Intracellular viability of the CZ171053 strain of C. pseudotuberculosis after one, three and six hours of interaction with J774 cells. The values at each time-point represent the number of viable bacteria recovered relative to the number recovered at the previous time-point, expressed as a percentage. The results are expressed as the mean ± standard deviation of two representative experiments performed in quadruplicate. *** represents a significant reduction in viability relative to the T1 wild-type (wt) strain at p < 0.0001 (ANOVA, Tukey’s test).
