Abstract

Two naturally infected dogs (male and female) from Teófilo Otoni (MG-Brazil) were maintained for 18 months in our laboratory. Two other dogs, two months old males were infected with 1 x 10(6) promastigotes of MHO/BR/70/BH46 Leishmania (Leishmania) chagasi strain, endovenous route, and autopsied after 10 months and two years. The main findings concerning the kidney were: (1) focal or diffuse mesangial glomerulonephritis with proliferative and enlargement of mesangial cells; (2) increase in thickness of basement membrane with electron-dense deposits; (3) chronic interstitial nephritis with intense exudation of plasmocytes; (4) cloud swelling of renal tubules. The authors discuss the probable pathogenetic mechanisms.
