Iintracellular growth of F. novicida and its isogenic mutant iglC in A. castellanii (A) and in H. vermiformis (B). The cells were infected for 15 min, followed by gentamicin treatment, and determination of the number of intracellular bacteria at the indicated time points. The error bars represent standard deviations of triplicate samples and results shown are representative of three independent experiments.
