Bursa of Fabricius in Chickens: Possible Humoral Factor
Science, 1965Chicks bursectomized by testosterone injection on the 5th day of incubation showed a marked inability to produce antibodies to Salmonella typhimurium . When portions of the bursa of Fabricius were enclosed in cell-impermeable Millipore diffusion chambers and implanted subcutaneously or intraperitoneally, the ...

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 ...

Epithelium of the Bursa of Fabricius Mucosa
Anatomia, Histologia, Embryologia, 2005The 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.

Ontogenic restriction of colonization of the bursa of Fabricius
European Journal of Immunology, 1983AbstractThe 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.

Histone fractions in chicken bursa of fabricius and thymus
Comparative Biochemistry and Physiology Part A: Physiology, 1973Abstract 1. 1. Whole histone and the five main histone fractions were isolated from chicken bursa of Fabricius and thymus. 2. 2. The proteins were all characterized by polyacrylamide gel electrophoresis and amino acid analyses and compared with the corresponding fractions from calf thymus. 3. 3.

In vitro organ culture of embryonic bursa of fabricius
Developmental & Comparative Immunology, 1990An in vitro method for organ culture of embryonic bursa of Fabricius is presented. It is shown that bursa cells proliferate in in vitro culture as evidenced by [3H]-thymidine incorporation. We assessed the expression of B-cell alloantigen (Bu-la and Bu-lb), class I (B-F) and class II (B-L) antigens of chicken major histocompatibility complex (MHC), and

Uptake of environmental antigens by the bursa of Fabricius
Nature, 1975THE bursa of Fabricius of birds has an essential role as a central lymphoid organ for the differentiation of B lymphocytes1,2. In addition, the bursa harbours immunocompetent B cells3 which are capable of local antibody production. Haemolytic plaque-forming cells have been observed in the bursa after introducing sheep red blood cells (SRBC) into the ...

The Bursa of Fabricius and Immunoglobulin synthesis
1977Publisher Summary This chapter discusses the Bursa of Fabricius and immunoglobulin synthesis. It emphasizes on bursa morphology, bursa kinetics, and bursa regulation of immunoglobulin production synthesis. Scanning electron microscope and transmission electron microscopy have revealed two distinct types of epithelial cells covering the plicae of the ...

Early Changes in Bursa of Fabricius from Marek's Disease
Avian Diseases, 1969SUMMARY Seventy Line 7 X specific-pathogen-free (SPF) hybrids were inoculated with four isolates of the Marek's disease (MD) agent. The strains used were the JM and Conn-A agents, chosen as standard isolates, and materials from two field outbreaks. Whole blood from infected donors was the source of inoculum; both undiluted and phosphate-buffered saline
