FIG. 6.

A more severe acute infection and lethality are observed in mice infected with PUS1 mutants. (A) Luminescence emitted from the body of the mouse, covering the head to the base of the tail, at the indicated days postinfection. The same three mice from each of two experiments, for a total of six mice per strain of parasite, were measured in this manner. Data are averages and standard deviations. (B) The survival of each infected mice was tracked daily during the infection and is shown as a Kaplan-Meier plot.
