No antibodies against Salmonella pullorum, Mycoplasma gallisepticum, Mycoplasma synoviae, Haemophilus gallinarum, fowl pox virus, Marek's disease virus, herpes virus of turkey, infectious laryngotracheitis virus, avian adenovirus, avian reovirus, infectious bursal disease virus, reticuloendotheliosis virus, avian leukosis virus, avian encephalomyelitis virus and Newcastle disease virus were detectable in the sera obtained from these chickens in 3 generations at various ages. Antibodies against infectious bronchitis virus were detected in the sera of the 3rd generations at 66, 74 and 108 weeks of age. The performances of these chickens was nearly the same as that of conventional healthy chickens in the poultry industry, with no tendency to decline.

The usefulness of the measurement of antibody titer to fowl pox virus (FPV) by enzyme-linked immunosorbent assay (ELISA) was evaluated in SPF chickens with or without inoculation with FPV. The optimum concentration of purified antigen was 10 micrograms/ml of protein. The absorbance at 492 nm was less than 0.10 in the chickens negative to FPV from 1 to 63 days old. By contrast, a higher titer was detected in SPF chickens with various FPVs inoculated into the wing web than in non-inoculated chickens. Moreover, there was no cross response to chicken sera immunized with Haemophilus paragallinarum, Marek's disease virus, Newcastle disease virus or infectious bronchitis virus. The titers increased after vaccination were not increased after subsequent challenge with virulent FPV. These findings suggested the usefulness of the measurement of the antibody response to FPV vaccine by ELISA.
