Bursa de Fabricius
Bursa de Fabricius (órgão linfóide, onde são formados os linfócitos B, responsáveis pela produção de anticorpos) é um divertículo oval em forma de saco na zona dorsal da parede do proctodeu, uma parte da cloaca das aves.
Este órgão está dividido em lóbulos poliédricos (folículos) por septos de tecido conjuntivo. Cada folículo apresenta córtex e medula. Uma camada de células epiteliais indiferenciadas ocupa a periferia da medula, que é separada do córtex por uma camada capilar. O lúmen é revestido por epitélio colunar pseudo-estratificado, excepto no ápice de cada folículo, que é revestido por um tufo epitelial de células colunares simples. O epitélio e o tecido linfóide subjacente formam pregas que se estendem para o lumen da bursa. Como no timo, a malha que suporta os linfócitos na bursa é formada por células epiteliais. Este órgão está presente em aves saudáveis até elas alcançarem a maturidade sexual. O intestino (porção retal) pode ser cortado após o exame da BF e deixado de lado para exame posterior.

Proteome Science | Full text | Optimized sample preparation for two-dimensional gel electrophoresis of soluble proteins from chicken bursa of Fabricius
Two-dimensional gel electrophoresis (2-DE) is a powerful method to study protein expression and function in living organisms and diseases. This technique, however, has not been applied to avian bursa of Fabricius (BF), a central immune organ. Here, optimized 2-DE sample preparation methodologies were constructed for the chicken BF tissue. Using the optimized protocol, we performed further 2-DE analysis on a soluble protein extract from the BF of chickens infected with virulent avibirnavirus. To demonstrate the quality of the extracted proteins, several differentially expressed protein spots selected were cut from 2-DE gels and identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS).

Animal Industry News Update: Bursa of Fabricius is a visual indicator
Part 1: //19 Dec 2011 The bursa of Fabricius is a lymphoid organ which plays an important role in developing immunity against mainly Gumboro in chickens. But does its size say anything? And can we easily correlate its changes to biological conditions? In this first of a series of two articles, the question is answered if differentiation in vaccination can be based on its appearance.
