title: Ubiquity of infectious bursal disease in East Texas backyard flocks.
abstract: Sera from 25 "backyard" flocks were screened by agar-gel precipitin (AGP) and virus-neutralization (VN) tests for antibodies to infectious bursal disease virus. Although titers varied from flock to flock, 100% of the birds screened had virus-neutralizing antibodies. In general, birds with high VN titers had positive AGP reaction.
