Exp Parasitol. 2008 Sep;120(1):123-5. doi: 10.1016/j.exppara.2008.06.004. Epub 2008 Jun 14.

Abstract

We infected Swiss and C57BL/6 female mice in the left hind footpad with 10(4)Leishmania (L.) amazonensis promastigotes in stationary phase. The macroscopic examination showed a nodular non-ulcerated lesion at the site of inoculation and hepatic and spleenic enlargement. Histopathologically, the primary lesion showed an extensive liquefactive necrosis and inflammatory infiltrate, mainly consisting of macrophages filled with amastigotes, and rare lymphocytes. The inflammatory reaction in liver, spleen and kidney showed amyloid deposits. Additionally, C57BL/6 had accentuated amyloidosis in both ovarian cortical and medullar region and inflammatory infiltrates in the pancreas and adrenal gland.
