Abstract
SUMMARY: A study was made to see if the exterior structures of the egg (cuticle, shell, and shell membranes) can support the growth of bacteria. Two species of common egg‐spoiling bacteria and a pathogenic bacterium were examined. The exterior structures supported extensive growth of all three organisms comparable to that found when the same bacteria were cultured in albumen. When these bacteria were seeded into sterile saline containing intact egg shells, they could he isolated, after some time, from the inside of the shell.
