Cell Transport and the Bursa of Fabricius [PDF]

Nature, 1966
THE use of grafts and parabionts with marked chromosomes in investigations on the mammalian thymus has shown that there is substantial cellular traffic in this organ1,2. Using chick parabionts, it should be possible to make an assessment of the role of cellular immigration in the development of the lymphoid organs of this species.

Chai Hu oral liquid enhances the immune functions of both spleen and bursa of Fabricius in heat-stressed broilers through strengthening TLR4-TBK1 signaling pathway

Poultry Science, 2021
: Heat stress can affect the poultry production and immune status of broilers. Heat stress disrupts intestinal integrity and increases intestinal inflammation, which is related with body immune dysfunction.

Atrophy of primary lymphoid organs induced by Marek’s disease virus during early infection is associated with increased apoptosis, inhibition of cell proliferation and a severe B-lymphopenia

Veterinary Research, 2018
Marek’s disease is a multi-faceted highly contagious disease affecting chickens caused by the Marek’s disease alphaherpesvirus (MDV). MDV early infection induces a transient immunosuppression, which is associated with thymus and bursa of Fabricius ...

Examination of macroscopic and microscopic lesions in IBDV-infected organs and molecular characterization of IBDV VP1 gene fragments obtained from commercial broiler farms in Indonesia [PDF]

Veterinary World, 2023
Background and Aim: Infectious bursal disease (IBD) is an infectious immunosuppressive disease that affects young chickens. Instead of strict biosecurity practices, vaccination is used to control IBD. However, the disease has not been effectively managed.

The Presence of Immunoglobulin in the Bursa of Fabricius ,

Poultry Science, 1967
Abstract Three-week-old birds were immunized with 40 mg. bovine serum albumin (BSA) per Kg. body weight. The bursa of Fabricius was removed 30 minutes after BSA injection and from another group of birds at 24-hour intervals for 5 consecutive days. The bursa was frozen −25°C. and sectioned in a cryostat (−25°C.) at 4 mμ.
