Histopathological profiles of ear lesions caused by L. amazonensis and L. braziliensis in wild-type and IL-32γTg mice. Fragments of ears from C57BL/6 WT and IL-32γTg mice uninfected (above) or infected with L. amazonensis (left) or L. braziliensis (right) for 3, 6 and 9 weeks were fixed and stained by hematoxylin & eosin, for analysis under a light microscope (100× magnification). A mononuclear cell inflammatory infiltrate was observed in the dermis that was progressive in L. amazonensis-infected and regressive in L. braziliensis-infected mice. Scale-bars: 100 μm
