The chicks of group </span><span>Β</span><span lang="EN-US"> received the D-78 vaccine strain with the drinking water at the age of 14 days, those of C at the age of 8 and 11 days, and those of D at the age of 8 and 16 days, while the chicks of the other groups (A and E) remained unvaccinated. In the following, the chicks of the A, B, C and D groups were infected with a field strain of Gumboro disease virus, while those of E remained unvaccinated and uninfected as a control group. After 10 days, all chicks were killed and their bursae examined histological. It was established that the histopathologic lesions to the bursae of group C chicks were of a slighter degree than those of all the other challenged groups and therefore the protection to bursa of Fabricius against the disease is better with this vaccination regimen.</span></p>}, number={2}, journal={Journal of the Hellenic Veterinary Medical Society}, author={BOUYIOUKLIS (Π.
