The Bursa of Fabricius

2015
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, a Source of Bluecomb Infectious Agent

Avian Diseases, 1972
SUMMARY Cell-free filtrates were prepared from bursae of Fabricius collected from bluecomb-infected turkey poults. Such filtrates were found uniformly infective when administered orally to bluecomb- susceptible poults under 7 days old. Evidence is presented that the bursa is a more satisfactory source of bluecomb agent for laboratory study than is the ...

The Bursa of Fabricius: A Central Issue

BioScience, 1970
Prior to 1955-56, the function of the avian and mammalian thymus and avian bursa of Fabricius was still an enigma. At this time, we revealed that removal of the bursa would reduce or eliminate future antibody production (Glick et al., 1956). Other investigators confirmed and extended this work to include that the mammalian and avian thymus control ...

Follicular exclusion of retroviruses in the bursa of fabricius

Virology, 1989
To gain insight into the regulation of retroviral infection at the cellular level, we analyzed the distribution of retroviral antigen and nucleic acid in the bursa of Fabricius of the parents and progeny of two highly inbred lines of chickens, one resistant and the other susceptible to infection. Line 15I5 chickens and line 7(2), which are C/C and C/A,

Antiserum Specific for Reticulin of the Bursa of Fabricius

International Archives of Allergy and Immunology, 1976
Antiserum produced by immunizing rabbits with embryonic chicken spleen cells showed, after appropriate absorption with cell suspensions, specificity for fetal spleen cells in membrane immunofluoresoence tests. However, when the original antiserum was absorbed with tissue homogenates and tested on cryostat tissue sections, it reacted specifically with ...

Shared Antigenicity between Chicken Brain and Bursa of Fabricius

International Archives of Allergy and Immunology, 1975
Antisera to chicken brain, thymus and bursa of Fabricius were prepared in rabbits and rendered organ-specific by appropriate absorptions. Brain was shown by immunofluorescence and immune adherence to have common antigenicity with the bursa of Fabricius but not with the thymus.

Apoptotic Cell Death in the Chicken Bursa of Fabricius

1996
The bursa of Fabricius is the site of primary B cell development in birds, and has been reviewed extensively elsewhere1–3. It is productively colonized during embryonic life by a small number (

Emigration of B cells from chicken bursa of Fabricius

European Journal of Immunology, 1989
AbstractThe extent of emigration of cells from the bursa of Fabricius to the periphery was estimated. Per anum application of fluorescein isothiocyanate to label bursal cells in situ was used. Migrant cells can be visualized on frozen sections or cell suspensions of peripheral organs by their fluorescence. The data show that at 2–3 weeks after hatching
