Serum chemistry and antibody status to some avian pathogens of free-living and captive condors (Vultur gryphus) of central Chile

Abstract

This study provides information on serology and serum chemistry of the Andean condor (Vultur gryphus). Twenty condors living under natural conditions were captured, blood sampled, measured, and released. In addition, 12 captive condors maintained at the Metropolitan Zoo of Santiago, Chile, were included as a comparison with free-living birds. All sera were negative to antibodies against reference strains of avian paramyxoviruses of serotypes 1 to 9, avian influenza and avian pox virus. Free-living condors had total protein, albumin, globulin and Mg values significantly (P ≤ 0.05) lower than those of captive birds. The haematological values obtained in bee-living condors are of particular interest since they may correspond to the optimum values of the species.
