SCANNING ELECTRON MICROSCOPIC STUDY OF THE BURSA OF FABRICIUS IN NORMAL AND IBD INFECTED CHICKEN

Abstract

Comparative assessment of the surface morphology of bursa of normal birds and from IBD infected birds of different age groups was made. The 1BD infected bursa showed various morphological alterations such as atrophy of the bursa) epithelium, sinking of follicle associated epithelium into the follicle and formation of craters of varying size whereas in normal chicken, the bursa showed normal physiomorphological changes consequent to the advancement of age
