In order to evaluate a potential protective role of spurious infection on the development of capillaria, mice were infected with non-embrionated eggs (spurious infection) followed by inoculation with embrionated eggs (true infection). The humoral immune response was evaluated through enzyme- linked immunosorbent assay (ELISA) that revealed a raise in anti-Capillaria hepatica IgG antibody two weeks after the first infection. Delayed type hypersensivity test was consistently negative. Histopathologic examination and the C. hepatica egg burden from different groups didnt show any significant variation. The humoral immune response induced by spurious infection do not protect mice against a true infection.
