FIGURE 6.
Alterations in the thymus relative weight after infection with P. yoelii (Py), L. braziliensis (Lb), L. amazonensis (La), or co-infection with Leishmania sp. and P. yoelii. Thymus relative weight in uninfected controls (open bars) were compared to those obtained in Py single-infected mice (black bars) and in animals co-infected (checkered bars) or single infected (gray bars) with L. braziliensis (A) or L. amazonensis promastigotes (B). Results are expressed by the mean ± SEM of 4–6 mice per group. The Mann–Whitney test was used to compare thymus relative weight between groups. (∗) statistically different from control, (#) statistically different from Leishmania single infection and (§) statistically different from Leishmania/P. yoelii co-infected group.
