The immunopathological evaluation of the hepatic compartment associated with parasitism and biochemical findings are essential for understanding the genesis of hepatomegaly in canine visceral leishmaniasis (CVL). Three clinical groups of dogs naturally infected with Leishmania chagasi [i.e., asymptomatic (AD, n = 12), oligosymptomatic (OD, n = 12) and symptomatic (SD, n = 17)] were assessed and compared with a group of non-infected dogs (NID, n = 11). Intense reaction of the Kupffer cells, capsule and portal inflammation, and the presence of intralobular granulomas, were observed in the different clinical groups. Dogs in the SD group presented a higher frequency of parasitism compared with the AD group. Inflammatory alterations were more intense in the SD group and were associated with parasitism. Our results indicated an association between histological liver changes and the progression of biochemical alterations according to progression of clinical forms of CVL, and the direct relationship between clinical symptoms and frequency of hepatic parasitism.
