Abstract:
:Immune responsiveness of three neonatal and juvenile phenotypes, determined by the albinotic C locus, was evaluated. The phenotypes included normally pigmented (C+/-), recessive white (c/ca), and completely amelanotic albinos (ca/ca). No differences in: (1) primary agglutinin levels directed against sheep red blood cells (SRBC) or Brucella abortus (BA), or (2) cell-mediated immunity, as estimated by in vivo mitogen stimulation, were associated with the albino phenotype. The significant suppression of secondary SRBC or BA agglutinins observed in albino chicks was limited and of questionable biological significance. Acquisition of passively transferred maternal BA agglutinins was significantly impaired in albino progeny irrespective of dam genotype. No differences in agglutinin levels were associated with dam genotype. In addition, uptake of yolk sac contents was retarded significantly in albino chicks at hatch. These data suggest that an impaired ability to absorb maternal antibody and not the capacity to mount an active immune response contributes to neonatal mortality in albino chicks.
