Immunoglobulin G class identification from wild ungulates by cross-reactivity with antisera to domestic animals

Seven species of Spanish ungulates were tested for the presence of homologo us immunoglobulin G (IgG) with a gel-diffusion test using bovine, ovine, ca prine and porcine IgG antisera. Homologous ovine and caprine IgG were detec ted in sera from chamois (Rupicapra pyrenaica), Spanish ibex (Capra pyrenai ca hispanica), mouflon (Ovis orientalis musimon), red deer (Cervus elaphus) , fallow deer (Dama dama) and roe deer (Capreolus capreolus). Homologous po rcine IgG was detected in wild boar (Sus scrofa) serum. Immunoelectrophoret ic assays were performed to compare the electrophoretic mobility of IgG fro m domestic and wild species.
