Baicalin attenuated Mycoplasma gallisepticum-induced immune impairment in the chicken Bursa of fabricius through modulation of autophagy and inhibited inflammation and apoptosis.

The Journal of the Science of Food and Agriculture, 2020
BACKGROUND Mycoplasma gallisepticum (MG) is the primary etiologic agent of chronic respiratory disease (CRD) in poultry. However, the mechanism underlying MG-induced immune dysregulation in chicken is still elusive.

Bursa of Fabricius and Immunological Tolerance

Nature, 1968
TRANSIENT and nonspecific suppression of antibody production can be induced in chickens by neonatal removal of the bursa of Fabricius1. The role of the bursa in the initiation and maintenance of specific immunological tolerance (paralysis, unresponsiveness)2, and the characteristic features of tolerant bursaless birds, however, have not been ...

Vasculogenesis of the bursa cloacalis (bursa of Fabricius) of the chick embryo

Journal of Morphology, 1981
AbstractVasculogenesis of the bursa cloacalis (bursa of Fabricius) was examined in 10‐ to 21‐day chick embryos and in chicks during the first 5 days post‐hatching. The entire circulatory system was injected with India ink, and the bursae were then removed and either cleared for examination in toto or sectioned serially.

Histomoniasis in the Bursa of Fabricius of Chickens

Avian Diseases, 2004
Histomoniasis was diagnosed in a flock of 6-wk-old commercial chickens. Clinical signs included depression, stilted gait, inappetence, and a slight increase in mortality. At necropsy, there were pale-yellow to dark-gray circular and depressed necrotic lesions in the liver. The ceca were enlarged and impacted with caseous cores.
