Student and successor of Andreas Vesalius (Fig. 3.1) and Gabriel Fallopius (Fig. 3.2), Girolamo Fabrici or Fabrizio (Fig. 3.3), was professor of Surgery at the University of Padova, Italy, from 1565 to 1613, and practiced and taught Anatomy (Smith et al. 2004). In 1594, he built the first permanent theatre ever designed for public anatomical dissection

Bursa of Fabricius and Immunological Tolerance [PDF]
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 ...

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.

The bursa of Fabricius is known to play a central role in the development of the antibody-producing B-lymphocyte lineage in birds. The bursa provides an appropriate microenvironment for gene conversion events leading to antibody diversification.

Histomoniasis in the Bursa of Fabricius of Chickens
Avian Diseases, 2004Histomoniasis 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.

Epithelium of the Bursa of Fabricius Mucosa [PDF]
Anatomia, Histologia, Embryologia, 2005 The structure and topography of the Bursa of Fabricius (BF) differs from other central immune organs. Structural components, providing BF function are located in mucosa, which is constantly influenced by antigen stimulation. Therefore the reports, which have appeared recently, indicate that BF may function as a peripheral immune organ.

Cryptosporidiosis of the Bursa of Fabricius of Chickens
Avian Diseases, 1975Light-microscope and electron-microscope studies of a coccidial organism found in the bursa of Fabricius from 3 chickens clearly established the parasite as belonging to the family Cryptosporiidae. Hyperplasia and heterophil infiltration were associated with the presence of organisms attached to the microvillus border of epithelial cells lining the ...

Vasculogenesis of the bursa cloacalis (bursa of Fabricius) of the chick embryo
Journal of Morphology, 1981AbstractVasculogenesis 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.

Ontogenic restriction of colonization of the bursa of Fabricius [PDF]
European Journal of Immunology, 1983 AbstractThe capacity of hemopoietic precursor cells (HPC) to home to embryonic bursal and thymic grafts was investigated in embryonic and newly hatched chickens. Whereas thymic grafts developed normal histogenesis in both types of recipients, the bursal rudiment was colonized and developed in embryonic, but not in newly hatched hosts.

Secretory cell in the medulla of the bursa of Fabricius
Experientia, 1978Light microscopy has revealed a possible secretory cell in the medulla of the bursa of Fabricius. Cyclophosphamide increased the presence of the secretory cell.
