ABSTRACT
Hamedi S., Age related changes in histology of the
Bursa of Fabricius in Japanese quails (Coturnix japonica), Onl J Vet
Res., 18(6): 468-471, 2014. Tissue
changes in the bursa of Fabricius in quails during
pre-puberty and puberty are described. Groups of 10 quails each were
slaughtered at 10, 20, 30 (pre-puberty) and 40 (puberty) days. Histological
sections from bursae were prepared and stained
with H&E. Plicae
were higher at puberty and the width of follicles and follicular medulla and
cortex increased with age. However, the number of follicles per plicae remained
constant in 10 and 20 day birds and only showed an increase in 30 and 40 day
specimens. The findings suggest that immune structures in the bursa develop at
puberty.
