Serum samples from seven randomly selected Minnesota turkey flocks were tested for antibodies to infectious bursal disease virus serotype I (Lukert strain, isolated from chickens, and North Carolina strain, isolated from turkeys) using a virus-neutralization (VN) test. All flocks were found to have low antibody titers to both Lukert and North Carolina strains. Five out of the seven flocks had high VN titers to the Missouri strain, a serotype II virus isolated from turkeys.
