The influence of silver nanoparticles on chicken embryodevelopment and bursa of Fabricius morphology

The aim of the experiment was to determine the influence of colloidal silver nanoparticles on the development of chicken embryos, particularly on the bursa of Fabricius. Silver nanoparticles (10 ppm) were injected into fertilized chicken eggs on days 5, 11 and 17. Ag nanoparticles did not influence embryo development as evaluated by the Hamilton and Hamburger standard. They did, however, decrease lymph follicular number and size, and changed the profile of the cell nuclei in the bursa of Fabricius.
