- The aim of this study was to describe the gross, histopathological and immunohistochemical features of non-specific reactive hepatitis (NSRH) in stray dogs. To perform this study the livers of 23 dogs of different breed and sex were used. The tissue sections were stained with hematoxylin–eosin, and immunohistochemically. The results of this work showed that NSRH was characterized by the infiltration of lymphocytes and plasma cells scattered throughout the liver parenchyma and in the portal stroma, and associated with inflammatory and non-inflammatory diseases in other organ systems. The inflammatory infiltrate of NSRH was composed of CD3+ T lymphocytes and HLA-DR+ lymphocytes, as well as IgG+ plasma cells and alpha-1-antitrypsin+ macrophages in the portal spaces and hepatic sinusoids.
