Morphology of bursa of Fabricius in bursectomized and thymectomized ducks.

Impaired host defense against XC cell-induced tumors in thymectomized and in bursectomized chickens.

XC cells originally derived from the tumor of a rat previously inoculated with the Prague strain of Rous sarcoma virus were used to induce tumors in chickens surgically thymectomized or bursectomized in the newly hatched period. Thymectomized chickens had a significantly higher incidence of tumors, larger tumors, and a higher tumor mortality, compared with control chickens, when both groups wer...

Effect of inoculation of bursa cells on the splenic lymphoid tissue of bursectomized and x-irradiated chickens.

HOSHI, H. Effect of Inoculation of Bursa Cells on the Splenic Lymphoid Tissue of Bursectomized and X-irradiated Chickens. Tohoku J. exp. Med., 1972, 108 (2), 113-121 Bursectomized and X-irradiated chickens were given intraperitoneal inoculation of live bursa cells in an attempt to restore the periellipsoidal lymphoid cells in their spleens. An injection of viable cells prepared from autologous ...

The Functions of the Thymus System and the Bursa System in the Chicken

The bursa of Fabricius and the thymus are "central lymphoid organs" in the chicken, essential to the ontogenetic development of adaptive immunity in that species. Surgical removal of one or both of these organs in the newly hatched chicken, followed by sublethal X-irradiation the next day, has permitted recognition of two morphologically distinct cell systems in the "peripheral lymphoid tissues...

Histological and Histochemical Studies of Harderian Gland, Lacrimal Gland and Bursa of Fabricius in Mulard Ducks (anas Sterilis) with Chlamydial Infection

Specimens from the Harderian gland, the lacrimal gland and bursa of Fabricius in ducks with chlamydiosis were processed by the classical histological methods and permanent preparations were obtained. On single and serial histological cross-sections from material fixed in non-aqueous fixator, histochemical tests for PAS reactivity, staining with alcian blue at pH 1.0 and 2.5 as well as staining ...

Histological and quantitative studies on the postnatal growth of the thymus and the bursa of Fabricius of White Pekin ducks.
