LEISHMANIA (LEISHMANIA) AMAZONENSIS: EXPERIMENTAL CUTANEOUS LEISHMANIASIS ASSOCIATED WITH SYSTEMIC AMYLOIDOSIS IN MICE
Author
Affilliation
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.
