Sera of 53 asymptomatic budgerigar breeders were studied for detecting precipitins and antibodies by radioimmunoassay against budgerigar serum antigen. The results were as follows:
1. Sixty percent of asymptomatic breeders and 30 percent of non-breeders showed positive precipitation reaction.
2. There was a discrepancy between the results of precipitation reaction and the presence of IgG anti-bodies measured by radioimmunoassay. Some subjects without precipitins had IgG antibodies and some subjects with precipitins had no IgG antibodies in serum.
3. IgG, IgA and, IgM antibodies were detected in 38%, 19% and 8% of asymptomatic breeders. IgE antibodies were not detected in any breeders. IgG antibodies were not detected in non-breeders.
4. The titer of IgG antibodies correlated with the numbers of budgerigars kept.
5. Much higher titers of IgG, A and, M antibodies were detected in a symptomatic breeder than asymptom atic breeders.
