Bursa of Fabricius, a Source of Bluecomb Infectious Agent
Avian Diseases, 1972SUMMARY 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 ...

Follicular exclusion of retroviruses in the bursa of fabricius
Virology, 1989To 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, 1976Antiserum 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 ...

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 ...

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

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.

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

Shared Antigenicity between Chicken Brain and Bursa of Fabricius
International Archives of Allergy and Immunology, 1975Antisera 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.

Studies of testosterone-induced involution of the bursa of Fabricius
Developmental Biology, 1980Abstract The present investigation deals with the effect of testosterone on each of the tissue components of the bursa of Fabricius: the endodermal epithelium, the mesenchyme, and the hemopoietic stem cells. Tissue combination experiments between testosterone-treated endoderm and normal mesenchyme and vice versa have shown that the androgen damages ...

Demonstration of Eimeria tenella in Bursa of Fabricius of Chickens
Avian Diseases, 1976Coccidial life-cytle stages were detected in the bursa of Fabricius of broiler chickens inoculated with Eimeria tenella, whether or not the chickens had previously been infected with infectious bursal disease virus (IBDV). Chickens infected only with E. tenella had developing parasites in the lining epithelium, whereas chickens with both infections had
