This study aimed to describe the occurrence of hepatic capillariasis in two non-human primates of the species Callithrix penicillata that were kept in captivity. Case 1 was in a young female, whose liver presented pale coloring, softening due to autolysis and several noticeably whitish areas. Case 2 was in a male of unknown age, whose liver was slightly pale and brownish. Histological analysis on the samples revealed extensive interstitial fibrosis with hemosiderotic areas. Adult nematodes of Capillaria hepatica and numerous eggs, morphologically characterized by their non-embryonic ellipsoid shape, with bipolar plugs that did not protrude from the shell, thick and birefringent, with a porous layer, thus giving a striated appearance to the eggs. Some cystic formations presented nematode eggs surrounded by numerous foreign-body giant cells. The literature consulted made little reference to reports of Capillaria hepatica in non-human primates. However, similar infections have been extensively studied in domestic rodents.
