Figure 6
Multiplication of yej gene deletion mutants and B. melitensis NI in J774.A1 macrophages.
At the indicated hour p.i., the number of intracellular bacteria was measured and expressed as log10 CFU/mL. The presented values represent the means of three experiments performed in duplicate and the error bars indicate the SD. Significant differences between every mutant and parental strain are indicated by an asterisk (P < 0.05).
