title: [Histogenetic study and mixed lymphocyte reaction in 2 lines of chickens homozygotic for haplotypes B14 and B19].
abstract: The histocompatibility status of homozygous chicken for B14 and B19 haplotypes of Hy-line stock origin was compared by skin grafts and the mixed lymphocyte reaction. No differences in graft survival (33 days) could be recorded in H-B compatible grafts in either haplotype tested. Reciprocal allografts however (B14 in equilibrium B19) were rejected within 12 days in both haplotypes. A weak stimulation index (1.3-1.9) persisted in individuals serologically identical with respect to the H-B complex whereas a strong index of 10.4 was obtained in allogeneic lymphocyte cocultures.
